# Cave Story Research Compendium
*A guide to Cave Story's file formats and important hacks*
**by fdeitylink**
**Last updated 2019-10-23**
## Rationale
* Learning more about Cave Story for my own edification
* File formats & important hacks weren't all published and collected
* Actually, they *are* included with Miza, but I hadn't realized this when beginning
## Notes
* Some information may be incorrect - S.P. Gardebiter's guides are a bit old. Feel free to tell me of any information that is incorrect or in need of an update.
* Cave Story was made for Windows and x86 architecture, which leads to some nuances to look out for
* Newlines are encoded as `\r\n` (affects TSC)
* Multibyte data is encoded in little endian format
## Credits
Big thanks to all of the following people for much of the following information!
* Carrotlord for the TSC file format
* q3hardcore for the (C)Pixel requirement removal hack
* S.P. Gardebiter for the PXA file format values, the executable mapdata format, and the `npc.tbl` format
* Noxid for Booster's Lab
* Used to determine how particular edits affected the files
* Provided newest information, especially tileset and sound values for `npc.tbl`
*WIthout further ado, let's begin!*
## Flags
### Setting Flags
Bitwise OR the current flags with the flag to set
`flags |= flag`
### Unsetting Flags
Bitwise XOR the flag to set with `0b1111_1111`
Bitwise AND the current flags with that result
`flags &= (flag ^ 0xFF)`
### Checking Flags
Bitwise AND the current flags with the flag to check
Returns flag if it is set, `0` otherwise
`is_set = (flags & flag)`
## TSC File Format
* The encoding character is the middle character in the file (i.e. the character at `floor(file_size / 2)`.
* For example, if the file size is 313 bytes, the encoding character is at the 156th byte.
* During encoding, all characters in the file, except for the encoding character itself, have the value of the encoding character added to them.
* To be clear, the encoding character itself, at the middle of the file, is *not* encoding, but other instances of it can be. If the encoding character was `a`, that one instance of `a` would not be encoded, but others would be.
* To encode a TSC file, add the value of the encoding character to all characters *except* for the encoding character.
* To be clear, do not encode the middle byte of the file
* It then follows that to decode a TSC file, subtract the value of the encoding character from each character
* Also note that newlines in TSC files are Windows-style (`"\r\n"`), so they take up two bytes that should each be treated as independent characters when encoding and decoding.
## Removing the `(C)Pixel` Requirement
| Offset | Old Value | New Value |
|-----------|-----------|-----------|
| `0x1136C` | `0x74` | `0xEB` |
| `0x8C4D8` | `0x28` | `0x00` |
In every `.pbm` file, find the `(C)Pixel` at the end and replace the `(` with the null character (`0x00`)
## Enabling bitmaps
| Offset | Old Value | New Value |
|---------------------------------|-----------|-----------|
| `0x8C286`, `0x8C30A`, `0x8C32E` | `0x70` | `0x62` |
| `0x8C287`, `0x8C30B`, `0x8C32F` | `0x62` | `0x6D` |
| `0x8C288`, `0x8C30C`, `0x8C330` | `0x6D` | `0x70` |
## `npc.tbl` Format
* Cave Story has 361 (`0x169`) entities numbered from 0 to 360
* `npc.tbl` contains 11 sets of data. The starting address of each set is a multiple of `0x169`.
* Each set of data contains the corresponding value for each entity, in order.
* For example: At offset `0x02D2` is the Health data for entity 0. At offset `0x02D4` is the Health data for entity 1.
| Offset | Description | Size per Entity (bytes) |
| ------------|------------------------|-------------------------|
| `0x0000` | Flags | 2 |
| `0x02D2` | Health | 2 |
| `0x05A4` | Tileset Number | 1 |
| `0x070D` | Death Sound | 1 |
| `0x0876` | Hurt Sound | 1 |
| `0x09DF` | Death Smoke | 1 |
| `0x0B48` | Experience | 4 |
| `0x10EC` | Damage | 4 |
| `0x1690` | Collision Bounding Box | 4 |
| `0x1C34` | Display Bounding Box | 4 |

-=~ Cave Story Research Compendium ~=-
-=~ A guide to Cave Story's file formats and important hacks for those who are interested ~=-
by F_Deity_Link, using research by others as well
Made it for myself to learn as well as because the file formats and important hacks weren't all 'published'
(actually they're in miza.chm, included with the Miza editor, but I hadn't realized this when I started),
and I figured a centralized document with all of it would be helpful
Last updated 2017-02-06
Note that some info might be incorrect - SP's guides are a bit old - feel free to tell me of anything that could be updated
-=~ Credits ~=-
Big thanks to all the people I got much of this research from!
- Carrotlord for TSC file format
- q3hardcore for (C)Pixel requirement removal
- S.P. Gardebiter for PXA values + EXE mapdata format + npc.tbl format
- dooey100 for flag setting, unsetting, and checking
- Noxid for Booster's Lab, which helped for seeing how edits affected the files, as well as getting newest info
- especially tilesets and sounds in npc.tbl
-=~ TSC File Format ~=-
Encoding char is the middle character in file: char at floor (file size / 2)
ex: size of 313 bytes, encode char is at 156th byte
Newlines are Windows-style newlines ("\r\n"): 0x0D + encode char val, then 0x0A + encode char val
- Because they're Windows-style newlines, open your files in binary mode, not text, otherwise the following transformations are done, which will end up corrupting the file
- "\r\n" --> '\n' for input
- '\n' --> "\r\n" for output
All characters in the file except for the encoding char itself (so other copies of the character are still encoded) have the value of the encoding char added to them when saved
ex: encoding char = [space]: only that instance of the [space] character will not be encoded, but the others will
When reading a TSC file, subtract the encoding character from each character (except the encoding char itself, as noted above) to properly decode the file
When writing a TSC file, add the encoding character to each character (except the encoding char itself, as noted above) to properly encode the file
-=~ Removing (C)Pixel Requirement ~=-
0x1136C: 0x74 --> 0xEB
0x8C4D8: 0x28 --> 0x00
Then in every .pbm, find the (C)Pixel at the end and change the '(' to the null character (0x00)
-=~ Allowing bitmaps ~=-
0x8C286 through 8 and 0x0008C30A through C: 0x70, 0x62, and 0x6D --> 0x62, 0x6D, and 0x70
0x8C32E and F: 0x70 and 0x62 --> 0x62 and 0x6D
0x8C330: 0x6D --> 0x70
-=~ npc.tbl Format ~=-
Cave Story has 361 entities (0x169) from 0 - 360
npc.tbl has 11 sets of data, the starting addresses of which are all multiples of 0x169:

0x05A4: Tileset Number - 1 Byte
0x070D: Death Sound - 1 Byte

WINDOWS IS LITTLE-ENDIAN AND ALL DATA (with the exception of PXM map tile and PXE entity count) TAKES UP TWO BYTES
ex: x coord of 256 (dec) is 0x0100, seen as 00 01 in hex editor
-=~ PXM File Data ~=-
maps must be minimum of 21x16
First three bytes are PXM, then 0x10
Then 0x_map_length - 2 bytes
Then 0x_map_height - 2 bytes
Then 0x_map_tile_from_tileset for the rest of the file (numbered from 0, and going left to right, top to bottom) - 1 byte
-=~ PXE File Data ~=-
First three bytes are PXE, then 0x00
Then 0x_entity_count - 4 bytes
Then each entity takes up 12 bytes, and they are in order based on their draw order (higher drawn on top) - lowest in file first:
0x_x_coord - 2 bytes
0x_y_coord - 2 bytes
0x_flag_num - 2 bytes
0x_event_num - 2 bytes
0x_entity_type - 2 bytes
0x_entity_flags - 2 bytes
-=~ Flags ~=-
Setting: Flag to set OR current flags
Unsetting: (Flag to unset XOR 1111 1111) AND current flags
Checking: Flag to check AND current flags - returns flag being checked if it is set, 0 if not set
-=~ PXA File Data ~=-
Format is tile type, corresponds to tileset directly - file has no header
Tilesets can be 16x16 tiles max, so PXA has 256 bytes, value of 0 for tiles not in tileset image
