Reverse Engineering Checklist

[sajattack]

• sceGuDebugPrint - Puzzle Bobble
• sceGim - Image Loading - Puzzle Bobble
• sceWave - Audio Loading - Puzzle Bobble
• sceSas - Seems like a software implementation of a basic synth - Yu-Gi-Oh
• sceVfpu - Vfpu intrinsics - Yu-Gi-Oh
• sceCcc - Character conversion (utf8 et-al) - Yu-Gi-Oh
• sceFpu - Fpu math - Yu-Gi-Oh
• sceGup - Similar to Gu - Yu-Gi-Oh
  sceLibFont - Font loading and rendering, NID based - Yu-Gi-Oh (in PPSSPP)
• sceMd5 - Statically linked MD5 functions - Adventure Player
• sceGmo - Models - Rengoku
• sceSs - More synth type stuff - Jan Sangoku Musou
• sceGiq - Seems similar to sceGim - Star Driver
• sceGmq - Seems similar to sceGmo - Star Driver
• scePaf - C++ Utilities? https://wiki.henkaku.xyz/vita/ScePaf, used in vsh modules
  sceMp4 - obviously mp4 - Star Driver (in PPSSPP)

These are in no particular order. I think sceVfpu should be top priority.

[sajattack]

Not reverse engineering because it's in PPSSPP already but since we're tracking libs not in pspsdk here, scePsmfPlayer is NID based video player type thing it seems. https://github.com/unknownbrackets/ppsspp/blob/master/Core/HLE/scePsmf.cpp

[sajattack]

sceLibFont is also available in PPSSPP

[sajattack]

Jan Sangoku Musou has a bunch of empty functions with strange names like sceVif, sceGs, sceCd, scePad, sceDbc. Stubs or something but I don't see where they're coming from because there's nothing unusual in rodata.sceResident

[sajattack]

Working theory is the Jan Sangoku Musou stuff was compiled for both PS2 and PSP, those are PS2 function names.

[sajattack]

It looks like sceCcc later became nid based like scePsmf did.

[sajattack]

Star Driver only has debug strings, not full debug symbols.

Dropping this here in the hope it might be of value. I'm the Raphael guy from that thread.

Edit: Found a better mirror, that also contains the other pages: http://lukasz.dk/mirror/forums.ps2dev.org/viewtopic35a4.html?t=6929

Thanks!

There's a leaked official Sony SDK on Archive.org that has headers and documentation for all of these. My understanding is that writing Rust function/struct definitions based on these isn't a copyright violation, but I understand if you want to be more cautious.

It's a lot of functions, so if I ever get around to writing something for the PSP that needs these I'll add just the ones I need.
