Great explaination. I think this was the last "unknown" part in the import lists thus prxtool could be extended for fully supporting the whole module information.

1) first, i was thinking about a static translator but i ran against some issues which are too complicated to be solved automaticaly : self-modified code, indirect jump or call by a register set during run-time and not compile-time, etc. ... 2) dynamic translator : that may be partly possible using...

groepaz: talking about the ME, is there a way to access it from game mode ? I know about the vector address being unreachable from this mode but there must be another way to do it using an already loaded library via a syscall or something ? You might try to research how the sce(Video|Audio)codec* r...

The options you have are: Hook into the export functions directly "redirecting" the actual export function's first instructions to your own (as noted by mbf) Hijack the resolved import table entry of all modules that import this function and redirect it to your own code Regarding why it is...

Your idea is indeed the most efficient way to emulate the PSX on the PSP and would offer at minimum equal framerates on the PSP. From what I know Sony's "PoPs" uses some sort of static recompilation or "static translation" aswell. They "translate" existing software once...

One (out of many) simple GUI based: 1. Get PS2Dis . 2. Use prxtool and the instructions from here . 3. Within PS2Dis press CTRL+G and select the NID/function you want ;) The other options are using the IDA Pro disassembler or, as you already noted, psp-objdump disassembly, just that you pass the fun...

[PATCH] Add PS2Dis MAP file serializer to prxtool

This patch adds a MAP label/comment file serializer to prxtool which is primary based on the IDC one. Make sure you loadup the module in PS2Dis as plain binary otherwise it attempts to map it (as PS2 ELF?) if it encounters ".ELF" as the file magic. Example use (including stripping the ELF ...

Good Job.

From my memdumps I could note these stubs are used for retrieving the information:

sceSystemFileGetIndexInfo
sceSystemFileGetIndex
sceSystemFileLoadIndex
sceSystemFileLoadAll2

Anyone actually succeeded in doing this on the PSP itself?

Great stuff! I think the initial work/focus should be to actually write a sample app which is recording audio input. Afterwards anything is possible. API wise it seems to be: sceHprmIsMicrophoneExist sceAudioInputInit sceAudioWaitInputEnd sceAudioGetInputLength sceAudioInput sceAudioInputBlocking Th...
