Microsoft Visual C++ Runtime Library

Surely 0x0100 is less than 4KB, why not try modify the amount to 0x1000 instead? And from "include", there is "PTHREAD_STACK_MIN" which is defined as 4096 (0x1000). Eh.. The implementation of sys_ppu_thread_create is not so accurate as it may be..

I read that section too and thought that to myself but I can't be sure without either testing it on a real PS3 or disassembling the lv2 lib.

And yeah, most of the lv2 function that are implemented are really inaccurate at the moment. Very few even return all of the possible errorcodes given in the SDK.

Well i only doubt why that is 0x100 but not 0x1000 selected, while 4KB is the smallest allocation unit. Just add a 0 may solve the problem, even you don't know why now - but you may get its reason later. I searched the web for some tips about how to programmatically get the stack size or overflow it to get its size, but without luck today.

Have fun developing it, devs.
PSX: PPC code is a little weird for one known ARM (Thumb). But i admit i don't know much about even x86.
PS2: PTHREAD_STACK_MIN is a macro defined in ppu toolchain's "pthread.h". So i even thought about trying to allocate 4096 bytes of ram in one thread and to see what happens with 4097+ bytes in another. That is a stupid way i admit..
PS3: I've reinstalled the os on my pc, and lost all those f**king MSVC.. Tired of waiting for the whole afternoon for MSVS installation..
