Hi there, i'm trying to port vio2play to the psp. vio2play is a nintendo ds sound format (2sf) player for linux.
I've already compiled a library with the vio2sf code and a simple test player. But when i try to run the app in the psp i get an 0x80020148 error, wich means 'Unsupported prx'. This error was supposed to occur when you tryied to run a 1.5 kernel app in a 3xx kernel if i'm not wrong (?)
But i'm creating the app as a user mode prx, so i don't know why i'm getting that error code.
Here is the simple player and the makefile:
| Code: |
#include <pspkernel.h>
#include <psppower.h>
#include <SDL/SDL.h>
#include "ao.h"
#include "corlett.h"
#include "vio2sf/vio2sf.h"
PSP_MODULE_INFO("vio2play", 0x0, 0, 1);

The only thing i have found is that something in the vio2sf code is causing it, because if i comment all vio2sf calls (xsf_something) the app loads and run fine. Does anyone have a clue of what is happening? I could share the code if anyone is interested.
Thanks in advance |
