Hi, this isn't an explored topic (Or at least found almost nothing around the internet.)
The PlayStation game Tomba! 2 (Or Tombi! 2 in Europe) is totally undocumented except for music & video, and seems to have it's own formats, I think it would be awesome to try to understand it's files and find a way to extract it's contents, models, textures...
(Sorry for the long read, I try to give all the info I can)
The game's disk (The Spanish version in this case, since is the one I own physically) contains Three folders:
MOVIEAnd four files:
Checked more versions of the game, and everything it's the same, the only changes are:
-Japanese version has a longer intro.
-the second file (Not folder) in the game has it's own regional code depending of the version obviously.
The rest of it it's the same.BIN folder content:
28 .BIN files
Since movies and sounds of this game are already extracted, I would focus on the Bin folder and the root files.
With a hex editor been inspecting some files, and this is what I've found so far:
START.BIN it's like an index file, it's short and list's file names like this:
found file name %s..\CD\VOICE.XA;1..\CD\
it continues for 3F4h bytes with illegible symbols.
Not checked every single hex code line of all files YET, but for now, the only .BIN that the MAIN.EXE file mentions in it's is the START.BIN, so probably it uses it to know what to load (it's absolutelly possible for me to be wrong, I'm only making deductions)
For now I didn't found anything I can understand in the numbered and A,B,C-ed .BIN files, but:
Then, in the file TOMBA2.DAT (Located in the CD folder) code, after a lot of symbol scroll, found this:
-a lot of 00 00 00 00 00 00-
-more 00 00 00 00 00 00-
This is probably related to what music plays or something like that since is in the cd folder, but it gives me two hints:
1-Those pack\pack_sp\area02.dat and comon.dat files are not visible in the game cd, so they seem like the kind of files psx games have in it's own way (odd way to explain it I'm sorry)
2-Levels are probably organized as "Area"s, if this is correct maybe it's useful to know it.
Some of the code I've pasted it's re-writen looking at screencaps I took yesterday because at this moment I can't go where the files are and just wanted to show how everything is organized, but feel free to ask me for exact copy, to attach something, or if you want to see another file, just ask it!
Going to continue inspecting the files as fast as I have a free moment.
