I don't know anything officially about this, but I would assume that sony would not allow anything like this. Any system that allows a user to run unsigned code is s huge security risk for them. The only outside posibility would probably to create some type of virtual machine but even that may pose ...

There are four steps to building the psp toolchain and if any one of those fail while using the toolchain.sh script, the entire process has to be restarted. You can partially work around this by building each part of the toolchain seperately, which will allow you to only rebuild that part that faile...

I think what you're looking for is sceKernelSleepThread(uint usec) which is accurate to the micro-second i believe

Speaking of audio, does anybody know if the psp supports any type of midi playback or if there is a decent library out there that would be able to do a midi to wav conversion at load time or real time. If so, I'd be willing to port it and add it to the sdk.

Well, I solved my own problem. By changing the line PSP_MODULE_INFO("MYGAME", 0, 1, 1); to PSP_MODULE_INFO("MYGAME", 0x1000, 1, 1); I was able to get the exception handler installed. Once I did this, I realized that the my exit callback wasn't getting hit when I chose to exit the...

Game freezes trying to install exception handler

I've tried to install an exception handler in my project following the code in the exception handler sample (in SVN), but whenever i run the line pspDebugInstallErrorHandler(MyExceptionHandler); the game freezes and the psp rebooots. I haven't changed anything, so I doubt that it's a bug that I've i...

it has to do with your RGB16 macro. Instead of taking the five most significant bits of each color, you're taking the five least. You should use

#define RGB(r,g,b) ((((b>>3) & 0x1F)<<10)|(((g>>3) & 0x1F)<<5)|(((r>>3) & 0x1F)<<0)|0x8000)

I solved my problem of catching the home key, when home is pressed the key value returned is '65536'. Hope that is what you were looking for maddogjt1.. That partially solves the problem. The problem is that when you bring up the "exit to home" screen, keyboard inupt is suspended to your ...

Pausing game when home button is pressed?

I have seen many titles that keep running in the background when the home button is pressed. The actual callback created by sceKernelRegisterExitCallback is only called when the exit is selected from the home button but I assume that there is another callback to the main thread that tells it to paus...

Register remap table

Since many people have asked about this and I haven't seen a complete list posted, this is how the registers from the ee-gcc toolchain map to the registers in the psp-gcc chain #define zero $0 #define v0 $2 #define v1 $3 #define a0 $4 #define a1 $5 #define a2 $6 #define a3 $7 #define t0 $8 #define t...
