Yesterday I got nostalgic and wanted to export the sprites from Star Ocean 2 on PSX.
I opened the iso of the game and found most of the data was in a .BIN file, after a quick look with a hex edit i noticed the occurance of SLZ a lot.
After googling a lot i eventually found this EXTREMELY helpful thread: https://www.romhacking.net/forum/index.php?topic=7790.20
After reading the breakdown from Cue and using the source code he provided I was able to modify his TriAce-ps2 code to work with Star Ocean 2.
Then use his code to uncompress the SLZ files.
I was hoping I would find all the texture files would be in an easy format like TIM or something however after extracting 6000 files and having a poke around there are only a handful of TIM files I could find, which looked more like loading screens.
Does anyone have any advice around what other formats are popular with triace games? What the header bytes would look like?
I did find some files with the header 28 00 00 00, which look like they might be sprite files.
I uploaded a sample of files here: https://easyupload.io/m/ctbdkc
the 2 files in the screenshots are 2192 and 2160.
Any advice or guidance would be much appreciated.
