+// dear imgui: Platform Binding for GLFW
+// This needs to be used along with a Renderer (e.g. OpenGL3, Vulkan..)
+// (Info: GLFW is a cross-platform general purpose library for handling windows, inputs, OpenGL/Vulkan graphics context creation, etc.)
+// (Requires: GLFW 3.1+)
+
+// Implemented features:
+//  [X] Platform: Clipboard support.
+//  [X] Platform: Gamepad support. Enable with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
+//  [X] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange' (note: the resizing cursors requires GLFW 3.4+).
+//  [X] Platform: Keyboard arrays indexed using GLFW_KEY_* codes, e.g. ImGui::IsKeyPressed(GLFW_KEY_SPACE).
+
+// You can copy and use unmodified imgui_impl_* files in your project. See main.cpp for an example of using this.
+// If you are new to dear imgui, read examples/README.txt and read the documentation at the top of imgui.cpp.
+// https://github.com/ocornut/imgui
+
+// CHANGELOG
+// (minor and older changes stripped away, please see git history for details)
+//  2020-01-17: Inputs: Disable error callback while assigning mouse cursors because some X11 setup don't have them and it generates errors.
+//  2019-12-05: Inputs: Added support for new mouse cursors added in GLFW 3.4+ (resizing cursors, not allowed cursor).
+//  2019-10-18: Misc: Previously installed user callbacks are now restored on shutdown.
+//  2019-07-21: Inputs: Added mapping for ImGuiKey_KeyPadEnter.
+//  2019-05-11: Inputs: Don't filter value from character callback before calling AddInputCharacter().
+//  2019-03-12: Misc: Preserve DisplayFramebufferScale when main window is minimized.
+//  2018-11-30: Misc: Setting up io.BackendPlatformName so it can be displayed in the About Window.
+//  2018-11-07: Inputs: When installing our GLFW callbacks, we save user's previously installed ones - if any - and chain call them.
+//  2018-08-01: Inputs: Workaround for Emscripten which doesn't seem to handle focus related calls.
+//  2018-06-29: Inputs: Added support for the ImGuiMouseCursor_Hand cursor.
+//  2018-06-08: Misc: Extracted imgui_impl_glfw.cpp/.h away from the old combined GLFW+OpenGL/Vulkan examples.
+//  2018-03-20: Misc: Setup io.BackendFlags ImGuiBackendFlags_HasMouseCursors flag + honor ImGuiConfigFlags_NoMouseCursorChange flag.
+//  2018-02-20: Inputs: Added support for mouse cursors (ImGui::GetMouseCursor() value, passed to glfwSetCursor()).
+//  2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
+//  2018-02-06: Inputs: Added mapping for ImGuiKey_Space.
+//  2018-01-25: Inputs: Added gamepad support if ImGuiConfigFlags_NavEnableGamepad is set.
+//  2018-01-25: Inputs: Honoring the io.WantSetMousePos by repositioning the mouse (when using navigation and ImGuiConfigFlags_NavMoveMouse is set).
+//  2018-01-20: Inputs: Added Horizontal Mouse Wheel support.
+//  2018-01-18: Inputs: Added mapping for ImGuiKey_Insert.
+//  2017-08-25: Inputs: MousePos set to -FLT_MAX,-FLT_MAX when mouse is unavailable/missing (instead of -1,-1).
+//  2016-10-15: Misc: Added a void* user_data parameter to Clipboard function handlers.

+//  2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.
+//  2018-08-03: OpenGL: Disabling/restoring GL_LIGHTING and GL_COLOR_MATERIAL to increase compatibility with legacy OpenGL applications.
+//  2018-06-08: Misc: Extracted imgui_impl_opengl2.cpp/.h away from the old combined GLFW/SDL+OpenGL2 examples.
+//  2018-06-08: OpenGL: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle.
+//  2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplOpenGL2_RenderDrawData() in the .h file so you can call it yourself.
+//  2017-09-01: OpenGL: Save and restore current polygon mode.
+//  2016-09-10: OpenGL: Uploading font texture as RGBA32 to increase compatibility with users shaders (not ideal).

+// CHANGELOG
+// (minor and older changes stripped away, please see git history for details)
+//  2020-05-08: OpenGL: Made default GLSL version 150 (instead of 130) on OSX.
+//  2020-04-21: OpenGL: Fixed handling of glClipControl(GL_UPPER_LEFT) by inverting projection matrix.
+//  2020-04-12: OpenGL: Fixed context version check mistakenly testing for 4.0+ instead of 3.2+ to enable ImGuiBackendFlags_RendererHasVtxOffset.
+//  2020-03-24: OpenGL: Added support for glbinding 2.x OpenGL loader.
+//  2020-01-07: OpenGL: Added support for glbinding 3.x OpenGL loader.
+//  2019-10-25: OpenGL: Using a combination of GL define and runtime GL version to decide whether to use glDrawElementsBaseVertex(). Fix building with pre-3.2 GL loaders.
+//  2019-09-22: OpenGL: Detect default GL loader using __has_include compiler facility.
+//  2019-09-16: OpenGL: Tweak initialization code to allow application calling ImGui_ImplOpenGL3_CreateFontsTexture() before the first NewFrame() call.
+//  2019-05-29: OpenGL: Desktop GL only: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag.
+//  2019-04-30: OpenGL: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
+//  2019-03-29: OpenGL: Not calling glBindBuffer more than necessary in the render loop.
+//  2019-03-15: OpenGL: Added a dummy GL call + comments in ImGui_ImplOpenGL3_Init() to detect uninitialized GL function loaders early.
+//  2019-03-03: OpenGL: Fix support for ES 2.0 (WebGL 1.0).
+//  2019-02-20: OpenGL: Fix for OSX not supporting OpenGL 4.5, we don't try to read GL_CLIP_ORIGIN even if defined by the headers/loader.
+//  2019-02-11: OpenGL: Projecting clipping rectangles correctly using draw_data->FramebufferScale to allow multi-viewports for retina display.
+//  2019-02-01: OpenGL: Using GLSL 410 shaders for any version over 410 (e.g. 430, 450).
+//  2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.
+//  2018-11-13: OpenGL: Support for GL 4.5's glClipControl(GL_UPPER_LEFT) / GL_CLIP_ORIGIN.
+//  2018-08-29: OpenGL: Added support for more OpenGL loaders: glew and glad, with comments indicative that any loader can be used.
+//  2018-08-09: OpenGL: Default to OpenGL ES 3 on iOS and Android. GLSL version default to "#version 300 ES".
+//  2018-07-30: OpenGL: Support for GLSL 300 ES and 410 core. Fixes for Emscripten compilation.
+//  2018-07-10: OpenGL: Support for more GLSL versions (based on the GLSL version string). Added error output when shaders fail to compile/link.
+//  2018-06-08: Misc: Extracted imgui_impl_opengl3.cpp/.h away from the old combined GLFW/SDL+OpenGL3 examples.
+//  2018-06-08: OpenGL: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle.
+//  2018-05-25: OpenGL: Removed unnecessary backup/restore of GL_ELEMENT_ARRAY_BUFFER_BINDING since this is part of the VAO state.
+//  2018-05-14: OpenGL: Making the call to glBindSampler() optional so 3.2 context won't fail if the function is a NULL pointer.
+//  2018-03-06: OpenGL: Added const char* glsl_version parameter to ImGui_ImplOpenGL3_Init() so user can override the GLSL version e.g. "#version 150".
+//  2018-02-23: OpenGL: Create the VAO in the render function so the setup can more easily be used with multiple shared GL context.
+//  2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplSdlGL3_RenderDrawData() in the .h file so you can call it yourself.
+//  2018-01-07: OpenGL: Changed GLSL shader version from 330 to 150.
+//  2017-09-01: OpenGL: Save and restore current bound sampler. Save and restore current polygon mode.
+//  2017-05-01: OpenGL: Fixed save and restore of current blend func state.
+//  2017-05-01: OpenGL: Fixed save and restore of current GL_ACTIVE_TEXTURE.

+// dear imgui: Renderer for modern OpenGL with shaders / programmatic pipeline
+// - Desktop GL: 2.x 3.x 4.x
+// - Embedded GL: ES 2.0 (WebGL 1.0), ES 3.0 (WebGL 2.0)
+// This needs to be used along with a Platform Binding (e.g. GLFW, SDL, Win32, custom..)
+
+// Implemented features:
+//  [X] Renderer: User texture binding. Use 'GLuint' OpenGL texture identifier as void*/ImTextureID. Read the FAQ about ImTextureID!
+//  [x] Renderer: Desktop GL only: Support for large meshes (64k+ vertices) with 16-bit indices.
+
+// You can copy and use unmodified imgui_impl_* files in your project. See main.cpp for an example of using this.
+// If you are new to dear imgui, read examples/README.txt and read the documentation at the top of imgui.cpp.
+// https://github.com/ocornut/imgui
+
+// About Desktop OpenGL function loaders:
+//  Modern Desktop OpenGL doesn't have a standard portable header file to load OpenGL function pointers.
+//  Helper libraries are often used for this purpose! Here we are supporting a few common ones (gl3w, glew, glad).
+//  You may use another loader/header of your choice (glext, glLoadGen, etc.), or chose to manually implement your own.
+
+// About GLSL version:
+//  The 'glsl_version' initialization parameter should be NULL (default) or a "#version XXX" string.
+//  On computer platform the GLSL version default to "#version 130". On OpenGL ES 3 platform it defaults to "#version 300 es"
+//  Only override if your GL version doesn't handle this GLSL version. See GLSL version table at the top of imgui_impl_opengl3.cpp.

+// stb_rect_pack.h - v1.00 - public domain - rectangle packing
+// Sean Barrett 2014
+//
+// Useful for e.g. packing rectangular textures into an atlas.
+// Does not do rotation.
+//
+// Not necessarily the awesomest packing method, but better than
+// the totally naive one in stb_truetype (which is primarily what
+// this is meant to replace).
+//
+// Has only had a few tests run, may have issues.
+//
+// More docs to come.
+//
+// No memory allocations; uses qsort() and assert() from stdlib.
+// Can override those by defining STBRP_SORT and STBRP_ASSERT.
+//
+// This library currently uses the Skyline Bottom-Left algorithm.
+//
+// Please note: better rectangle packers are welcome! Please
+// implement them to the same API, but with a different init
+// function.

+# `accurate` branch
+Being a pure, plain decompilation of the original `Doukutsu.exe` file (v1.0.0.6),
+there should not be much to say about this branch's philosophies:
+
+## Goal
+The end-goal is for the project to be able to produce an `.exe` file that is
+identical to the original. This means that there should be no custom code,
+decompiled code should ideally be made to produce the same assembly code as the
+original, bugs should be left intact, etc.
+
+Another goal of the project is to document Cave Story's inner-working, so code
+should be reasonably-annotated. Likewise, bugs should be documented, and fixes
+provided wrapped in `#ifdef FIX_BUGS` conditions.
+
+## Accuracy to the original source code
+Personally, I do aim to make the decompiled code _functionally_-accurate to the
+original, down to generating the same assembly code, but I do not aim for
+_visually_-accurate code.
+
+Despite this, I do try to preserve the original function/variable names,
+variable-declaration locations, and source file naming.
+
+Part of the reason why I do not aim for visually-accurate source code is that we
+know from the [Organya source code release](https://github.com/shbow/organya/)
+what Pixel's code-style looked like, and I find it **extremely** hard to read.
+
+## Language
+Cave Story's developer (Pixel) primarily speaks Japanese, but his code's
+variable/function names are mostly written in English (with a few rare instances
+of Romanised Japanese).
+
+The Organya source code release indicates that Pixel wrote his comments in
+Japanese, however, in this project, I prefer them to be written in English.
+
+The English employed in this project is a mix of American English, Canadian
+English, and British English.
+
+
+
+# `portable` branch
+This branch takes a different direction to the `accurate` branch, but they still
+share many core philosophies:
+
+## Goal
+While accurately-reproducing Cave Story's original code is still a priority, the
+main focus of this branch is to port the game to other platforms, while also
+preserving the game the way it was experienced back in 2004.
+
+Essentially, this branch exists to provide a purist Cave Story experience
+without requiring an old Windows XP computer.
+
+Notably, this means that bugs should still be left intact. However, bugs and
+other coding errors that affect portability should be fixed.
+
+For comparison, I believe this branch shares many parallels with the
+Chocolate Doom project. Follow the link below to see that project's list of
+philosophies, which may be applicable here:
+
+https://github.com/chocolate-doom/chocolate-doom/blob/master/PHILOSOPHY.md
+
+## Custom code
+Cave Story's original source code was written in C++, but stylised like C89
+(with a number of exceptions). Custom code added to the project should follow
+suit, but the C-style doesn't have to be C89 - personally, I prefer to write in
+the subset of C99 that C++98 allows.
+
+I prefer compiler-specific code to be avoided, since more-portable code benefits
+all compilers, and keeps the codebase free of clutter.

+
+## Table of Contents
+
+This repo has two main branches:
+
+Branch | Description
+--------|--------
+[accurate](https://www.github.com/Clownacy/CSE2/tree/accurate) | The main decompilation branch. The code is intended to be as close to the original as possible, down to all the bugs and platform-dependencies.
+[portable](https://www.github.com/Clownacy/CSE2/tree/portable) | This branch ports the engine away from WinAPI and DirectX, and addresses numerous portability issues, allowing it to run on other platforms.
+
+# CSE2 (Portable)
+
+CSE2 is a decompilation of Cave Story.
+
+This branch migrates the engine away from WinAPI and DirectX, and addresses
+numerous portability issues, allowing it to run on other platforms.
+
+Supported platforms include...
+* Windows
+* Linux
+* macOS
+* Wii U
+* 3DS
+* RISC OS
+
+![Screenshot](images/screenshot.png)
+
+## Background
+
+When Pixel made Cave Story, he compiled the original Windows EXE with no
+optimisations. This left the generated assembly code extremely verbose and easy
+to read. It also made the code very decompiler-friendly, since the assembly
+could be mapped directly back to the original C++ code.
+
+Technically, this alone made a decompilation feasible, as was the case for [the
+Super Mario 64 decompilation project](https://github.com/n64decomp/sm64) -
+however, there was more to be found...
+
+In 2007, a Linux port of Cave Story was made by Simon Parzer and Peter Mackay.
+Details about it can be found on [Peter's old blog](https://web.archive.org/web/20070911202919/http://aaiiee.wordpress.com:80/).
+This port received an update in 2011, including two shiny new executables. What
+they didn't realise was that they left huge amounts of debugging information in
+these executables, including the names of every C++ source file, as well as the
+variables, functions, and structs they contained.
+
+This was a goldmine of information about not just the game's inner-workings, but
+its _source code._ This is the same lucky-break [the Diablo decompilation project](https://github.com/diasurgical/devilution)
+had. With it, much of the game's code was pre-documented and explained, saving
+us the effort of doing it ourselves. In fact, the combination of
+easy-to-decompile code, and a near-full set of function/variable names, reduced
+much of the decompilation process to mere copy-paste.
+
+To top it all off, some of Cave Story's original source code would eventually
+see the light of day:
+
+In early 2018, the Organya music engine was [released on GitHub](https://github.com/shbow/organya)
+by an old friend of Pixel's. On top of providing an insight into Pixel's coding
+style, this helped with figuring out one of the most complex parts of Cave
+Story's codebase.
+
+And... that's it! It's not often that a game this decompilable comes along, so
+I'm glad that Cave Story was one of them. [Patching a dusty old executable from 2005 sucks](https://github.com/Clownacy/Cave-Story-Mod-Loader/blob/master/src/mods/graphics_enhancement/widescreen/patch_camera.c).
+
+## Dependencies
+
+* SDL2 (if `BACKEND_AUDIO` or `BACKEND_PLATFORM` are set to `SDL2`)
+* SDL (if `BACKEND_AUDIO` or `BACKEND_PLATFORM` are set to `SDL1`)
+* GLFW3 (if `BACKEND_PLATFORM` is set to `GLFW3`)
+* FreeType (if `FREETYPE_FONTS` is enabled)
+
+If these are not found, they will be built locally (with the exception of SDL).
+
+In addition, `pkg-config` is required for builds that require static-linkage.
+
+A list of dependencies for specific platforms can be found [on the wiki](https://github.com/Clownacy/CSE2/wiki/Dependency-lists).
+
+## Building
+
+This project uses CMake, allowing it to be built with a range of compilers.
+
+(A beginner-friendly guide can be found in [VISUAL_STUDIO_2019_GUIDE.md](VISUAL_STUDIO_2019_GUIDE.md))
+
+Switch to the terminal (Visual Studio users should open the [Developer Command Prompt](https://docs.microsoft.com/en-us/dotnet/framework/tools/developer-command-prompt-for-vs))
+and `cd` into this folder. After that, generate the files for your build system
+with:
+
+```
+cmake -B build -DCMAKE_BUILD_TYPE=Release
+```
+
+MSYS2 users should append `-G"MSYS Makefiles" -DPKG_CONFIG_STATIC_LIBS=ON` to
+this command, also.
+
+You can also add the following flags:
+
+Name | Function
+--------|--------
+`-DJAPANESE=ON` | Enable the Japanese-language build (instead of the unofficial Aeon Genesis English translation)
+`-DFIX_BUGS=ON` | Fix various bugs in the game
+`-DDEBUG_SAVE=ON` | Re-enable the ability to drag-and-drop save files onto the window
+`-DDOCONFIG=OFF` | Disable compiling the DoConfig tool (it is not useful for console ports)
+`-DDOCONFIG_LEGACY_OPENGL=ON` | Make DoConfig use OpenGL 2.1 instead of OpenGL 3.2 (useful for older/limited platforms)
+`-DLANCZOS_RESAMPLER=ON` | Use Lanczos filtering for audio resampling instead of linear-interpolation (Lanczos is more performance-intensive, but higher quality)
+`-DFREETYPE_FONTS=ON` | Use FreeType2 to render the DejaVu Mono (English) or Migu1M (Japanese) fonts, instead of using pre-rendered copies of Courier New (English) and MS Gothic (Japanese)
+`-DBACKEND_RENDERER=OpenGL3` | Render with OpenGL 3.2 (hardware-accelerated)
+`-DBACKEND_RENDERER=OpenGLES2` | Render with OpenGL ES 2.0 (hardware-accelerated)
+`-DBACKEND_RENDERER=SDLTexture` | (Default) Render with SDL2's Texture API (hardware-accelerated) (note: requires `-DBACKEND_PLATFORM=SDL2`)
+`-DBACKEND_RENDERER=SDLSurface` | Render with SDL2's Surface API (software-rendered) (note: requires `-DBACKEND_PLATFORM=SDL2`)
+`-DBACKEND_RENDERER=WiiU` | Render with the Wii U's GX2 API (hardware-accelerated)
+`-DBACKEND_RENDERER=3DS` | Render with the 3DS's Citro2D/Citro3D API (hardware-accelerated)
+`-DBACKEND_RENDERER=Software` | Render with a handwritten software-renderer
+`-DBACKEND_AUDIO=SDL2` | (Default) Deliver audio with SDL2 (software-mixer)
+`-DBACKEND_AUDIO=miniaudio` | Deliver audio with miniaudio (software-mixer)
+`-DBACKEND_AUDIO=WiiU-Hardware` | Deliver audio with Wii U's AXVoice API (hardware-accelerated) (WARNING - currently broken: voices randomly disappear for unknown reasons)
+`-DBACKEND_AUDIO=WiiU-Software` | Deliver audio with Wii U's AXVoice API (software-mixer)
+`-DBACKEND_AUDIO=3DS-Hardware` | Deliver audio with 3DS's NDSP API (hardware-accelerated)
+`-DBACKEND_AUDIO=3DS-Software` | Deliver audio with 3DS's NDSP API (software-mixer)
+`-DBACKEND_AUDIO=Null` | Don't deliver audio at all (WARNING - game will have no audio)
+`-DBACKEND_PLATFORM=SDL2` | (Default) Use SDL2 for miscellaneous platform-dependant operations
+`-DBACKEND_PLATFORM=GLFW3` | Use GLFW3 for miscellaneous platform-dependant operations
+`-DBACKEND_PLATFORM=WiiU` | Use the Wii U's native APIs for miscellaneous platform-dependant operations
+`-DBACKEND_PLATFORM=3DS` | Use the 3DS's native APIs for miscellaneous platform-dependant operations
+`-DBACKEND_PLATFORM=Null` | Don't do platform-dependant operations at all (WARNING - game will have no video or input)
+`-DLTO=ON` | Enable link-time optimisation
+`-DPKG_CONFIG_STATIC_LIBS=ON` | On platforms with pkg-config, static-link the dependencies (good for Windows builds, so you don't need to bundle DLL files)
+`-DMSVC_LINK_STATIC_RUNTIME=ON` | Link the static MSVC runtime library, to reduce the number of required DLL files (Visual Studio only)
+`-DFORCE_LOCAL_LIBS=ON` | Compile the built-in versions of SDL2, GLFW3, and FreeType instead of using the system-provided ones
+
+You can pass your own compiler flags with `-DCMAKE_C_FLAGS` and `-DCMAKE_CXX_FLAGS`.
+
+You can then compile CSE2 with this command:
+
+```
+cmake --build build --config Release
+```
+
+If you're a Visual Studio user, you can open the generated `CSE2.sln` file
+instead, which can be found in the `build` folder.
+
+Once built, the executables can be found in the `game_english`/`game_japanese`
+folder, depending on the selected language.
+
+### Building for the Wii U
+
+To target the Wii U, you'll need devkitPro, devkitPPC, and WUT.
+
+First, add the devkitPPC tools directory to your PATH (because WUT's CMake
+support is broken, as of writing):
+
+```
+PATH=$PATH:$DEVKITPPC/bin
+```
+
+Then, generate the build files with this command:
+
+```
+cmake -B buildwiiu -DCMAKE_BUILD_TYPE=Release -DFORCE_LOCAL_LIBS=ON -DBACKEND_PLATFORM=WiiU -DBACKEND_RENDERER=WiiU -DBACKEND_AUDIO=WiiU-Software -DDOCONFIG=OFF -DCMAKE_TOOLCHAIN_FILE=$DEVKITPRO/wut/share/wut.toolchain.cmake
+```
+
+Finally, build the game with this command:
+
+```
+cmake --build buildwiiu
+```
+
+This will build a binary, but you still need to convert it to an `.rpx` file
+that can be ran on your Wii U.
+
+First, we need to strip the binary:
+
+```
+powerpc-eabi-strip -g game_english/CSE2
+```
+
+Then, we convert it to an `.rpx`:
+```
+elf2rpl game_english/CSE2 game_english/CSE2.rpx
+```
+
+`game_english/CSE2.rpx` is now ready to be ran on your Wii U. This port expects
+the data folder to be in a folder called `CSE2-portable-en`/`CSE2-portable-jp`
+on the root of your SD card.
+
+### Building for the 3DS
+
+To target the 3DS, you'll need devkitPro, devkitARM, Citro2D, Citro3D, libctru,
+and bannertool, along with the `3dstools` and `devkitpro-pkgbuild-helpers`
+packages.
+
+Open a terminal, and `cd` into the CSE2 directory. Then execute this command:
+
+```
+cmake -B build3ds -DCMAKE_BUILD_TYPE=Release -DFORCE_LOCAL_LIBS=ON -DBACKEND_PLATFORM=3DS -DBACKEND_RENDERER=3DS -DBACKEND_AUDIO=3DS-Hardware -DDOCONFIG=OFF -DFREETYPE_FONTS=ON -DCMAKE_TOOLCHAIN_FILE=$DEVKITPRO/3ds.cmake
+```
+
+(Note that `FREETYPE_FONTS` is enabled. If you're creating a Japanese build,
+it's best to disable this, as the FreeType font is unreadable at 320x240).
+
+This will create the build files. To build CSE2, run:
+
+```
+cmake --build build3ds
+```
+
+This will create an elf file. Before we can create a `.3dsx` file from it, we
+need to make an `.smdh` file:
+
+```
+bannertool makesmdh -i $DEVKITPRO/libctru/default_icon.png -s "CSE2" -l "Port of Cave Story" -p "Clownacy" -o build3ds/smdh.smdh
+```
+
+We can finally generate a `.3dsx` file:
+
+```
+3dsxtool game_english/CSE2 game_english/CSE2.3dsx --romfs=game_english/data --smdh=build3ds/smdh.smdh
+```

+So you want to compile CSE2?
+
+Well, to start, you'll need Visual Studio. I know a lot of people
+recommend MSYS2 instead, and while it is a lot more lightweight, it's
+also way more complex, and outright broken in some places, which will
+make compiling an absolute nightmare (I'm looking at you, Brotli).
+
+So, we'll be using Visual Studio Community 2019. Don't worry - it's
+free. You can download it here:
+
+https://visualstudio.microsoft.com/
+
+Once it's downloaded, run `vs_Community.exe`. Follow the installer until
+you reach this menu:
+
+![Screenshot](images/vs2019guide1.png)
+
+Here, you'll want to select the 'Desktop development with C++' workload,
+and then click 'Install'. Once it's done installing, you'll be prompted
+to restart your computer.
+
+Next, download a copy of CSE2's source code if you haven't already and
+extract it somewhere. You can find a copy of CSE2 Portable's code here:
+
+https://github.com/Clownacy/CSE2/archive/portable.zip
+
+You are now ready to compile CSE2. To begin, open Visual Studio 2019. If
+it prompts you to open a project, select 'Continue without code' to skip
+past it and enter the main IDE. It should look something like this:
+
+![Screenshot](images/vs2019guide2.png)
+
+From here, select `File/Open/CMake`, and then navigate to where you
+extracted the CSE2 source code, and open the `CMakeLists.txt` file.
+
+After this, Visual Studio will spend a few minutes configuring itself.
+You can see all of this in the little text console at the bottom of the
+window. Eventually, it will conclude, and hopefully not report any
+errors. The window should now look something like this:
+
+![Screenshot](images/vs2019guide3.png)
+
+You are now able to produce 64-bit Debug builds of CSE2. To do so,
+simply select `Build/Build All`. Like before, Visual Studio will spend
+the next few minutes performing tasks, and reporting back in the text
+console. It should eventually generate `CSE2_debug.exe` and
+`DoConfig_debug.exe`, which you can find in CSE2's `game_english`
+folder.
+
+However, you probably want to be compiling Release builds, not Debug
+builds. To do so, select the 'Open the CMake Settings Editor' option. It
+will take you to this menu:
+
+![Screenshot](images/vs2019guide4.png)
+
+From here, change the 'Configuration type' option to 'Release'. You can
+now rebuild CSE2, and the files `CSE2.exe` and `DoConfig.exe` will be
+generated in the `game_english` folder.
+
+And... that's it. If you want, you can edit CSE2's code by expanding the
+`src` folder on the right, and selecting one of the various `.cpp`
+files.
