ROM Hacking Discussion / [PSX] PS-X EXE aka SLUS
« on: July 17, 2018, 08:27:41 am »
Hello everyone, I need advice on how to inject code into the SLUS without breaking it or my injected code be overwritten by the game.
- First possible solution is to find a blank spot in the SLUS but the problem here is that my code may be overwritten.
- Second solution that I use, but is no elegant: most of the SLUS (even PS2 ones) have these strings CdlReadS, CdlSeekP, CdlSeekL, CdlGetTD, CdlGetTN... many more, these are all the time is the same spot on the RAM, I write my code in this space and works on a real console with burned CD-R.

Any person with more knowledge about an elegant solution of doing this, thanks.

Hello, I need some help with this game compression method.
I use QuickBMS to help me a little and I got little parts decompressed, it looks like is an LZS variant.
COMP_LUNAR_LZ10, // scan 260
COMP_HEATSHRINK, // scan 497
COMP_LHA_lzs,   // scan 526
DMP files, memory dump and compressed files here:

The decompression function on the debugger start at address 80010050 but I don't know much MIPS.

Thanks in advance.
