I found some 8bytes numbers starting with 0x80 that could be pointers. So Q4 : Is it doable to edit a PSX application without corrupting it? Where am I the most likely to find pointers in my LOADER.EXE? I searched for them but found nothing, I supposed the format was different. (Oh, yes, I didn't precised there were datas too in the LOADER.EXE, basicly some uncompressed graphics used when you launch the game, AND as it happens, my audio pointers) I then assumed they were MORE pointers in the executable itself to access certain zones of data.

I tested this with ePSXe and the ISO WORKED! But when I attached a debugger to the game and tried to search for my pointers list, the one I added wasn't here. When I did this, my files where truncated (normal since I did this with CDMage). I tried to add a music I composed in SEQ and VAB in the sound file and added a pointer to the list in LOADER.EXE Pretty logical since the music doesn't depend on the level in which you are. It contains all the pointers needed to access SEQ and VAB datas for the sound. Most of them are in the main data header file, but some of them are located in the loader application used by the PS1 (LOADER.EXE). Q3 : Do I need to know something else to make that work?Īnother thing, I found pretty all pointers that lead to datas in the game files.

Q2 : Is it easier/safer to edit the xml myself? Q1 : Would mkisoxml help me to arrange files in my ISO the exact same way they are in the original?

When I tried to rebuild an ISO of the game from scratch with mkpsxiso then opened it with CDMage, I noticed all LBA changed (which is normal, I didn't precised the order of the files in my ISO, but I'm not sure how to do it) I then tried to use mkpsxiso, but I'm pretty new to that and everything isn't clear to me. You can use it to replace files in an original ISO, but they can't exceed original size, otherwise your edited file will be truncated. To exact files from the ISO, I use CDMage which works like a charm. My soft can extract raw datas, edit and eventualy recompress them, but the final size is pretty random.Ĭonclusion : I need to find a way to enlarge the ISO size (which seems to be a pain).
