[WIP+RELEASE] lpp.prx - Create PSP/PSVITA plugins in LUA

[Joel16]

I'm busy with exams at the moment but I managed to squeeze in some time for testing. I won't be able to starting from tomorrow. And I've tried both with and without the modifications of lua system.c with the isPSP bit removed in the script, it just displays as, "model: 5000" Lol.

System.getModel patched. With isPSP modification, your PSP must be recognized as a PSP. What the function does is to search in your PSP/GAME a folder which contains an FBOOT.PBP (on PSVITA, EBOOT.PBP are renamed as FBOOT.PBP due to Sony limitations), if it found a FBOOT.PBP so it return 0, if not, it return 1.

Patched getModel source:

Code: Select all

static int lua_getModel(lua_State *L)
{
    char stringa[256];
    int argc = lua_gettop(L);
    if (argc > 0)
    {
        return luaL_error(L, "System.getModel() takes no argument");
    }
    int model;
    model = ((kuKernelGetModel() + 1) * 1000);
    if (model == 4000 || model == 5000){
    sprintf(stringa, "N1000");
    }else if(model == 10000){
	sprintf(stringa, "E1000");
	}else{
    sprintf(stringa, "%i", model);
    }
    lua_pushstring(L, stringa);
    return 1;
}

I'll have a look later, whenever I get some free time.

Little update:
Added System.startPSX (start a PBP file with POPS) and Kernel.loadWord (porting of _lw C function).
Improved PSP GO support.

Great project but what happened to LPP?

[Rinnegatamante]

NaNNi was working on the latest LPP version (lpp-c++ trunk) but he currently stopped to update it. Probably, it will be updated in future with new functions like PMF support, 3D model support (OBJ) and other stuffs.

[Rinnegatamante]

Finally finished my school exams.

Added two new functions:

Code: Select all

System.restart() - Restart interpreter
System.getFileSize(string filename) - Get size in bytes of a file

Moved Kernel class to luaKernel.c

I decided also to publish a new official release so here you are:
