Compiling 3.71 PRXs and PRXs in General

[JaSo PsP]

Basically, I want to be able to know how to make XMB and GAME plugins for my 3.71 PSP. I do not know how to compile any PRX for 3.71 or any firmware for that matter. I've searched over the net for tutorials/examples but I still do not know what to do. I also want to be able to blit images and text to the screen in either mode. Where do I begin? I'm requesting help regarding:

- Any tools I need for PRX compilation.
- The way the Makefile should look.
- Maybe a template for a simple 3.71 PRX in GAME mode or XMB mode.
- A library that I can use to blit images and text to the screen in the XMB or in GAME that is compatible with 3.71.

Any help appreciated, thanks.

you would have to ask someone who knows how to make plugins with the new NIDS. Maybe CoolJ or Ketchup would know.

Yes.. I'd help you with that ate, but I'm still on 3.52m33-4

Though, I remember that someone posted here a tool for autoatically changing the NID's for ya. Basically you can just do all your stuff by the old fashion way, and it'll convert for you. That way you can also learn by the final result.

Look inside the pspsdk samples. There's several templates for making prxes. That's what the samples are for.

I don't even know the old-fashioned way, I've seen that you have to do 'mainThread' crap I, it is as simple as putting 'BUILD_PRX = 1' in the makefile?

Look for the sample here:

usr\local\pspdev\psp\sdk\ samples\prx\testprx

What 'mainThread' crap?

#include <pspkernel.h>
PSP_MODULE_INFO("PRX",0x1000,1,1);

int function(SceSize argc, void* argp)
{
    return 0;
}

int module_start(SceSize argc, void* argp)
{
    int id=sceKernelCreateThread("thread_name",function,0x20,0x1000,0,0);
    if(id >= 0) sceKernelStartThread(id,argc,argp);
}

Or you could just do everything in the module_start function without creating another thread, but probably wouldn't want to do that anyway.

How do I compile it for 3.71 though? I tried making a kernel mode PRX that created a text file wen it loaded in the XMB and it didnt work.

[Anti-QuickJay]

BUILD_PRX=1
PSP_FW_VERSION=303

CFLAGS = -DPSPFW3X

Something like that needs to be added to your Makefile

AFAIK, your main module cannot be kernel-mode. You have to make it user-mode, and all kernel-mode functions have to be called from a kernel-mode PRX that your user-mode PRX loads.

As far as I know,your main module can and should be in kernel mode.

your prx should be in kernel mode. if you have got the latest toolchain look in pspdev/psp/sdk/samples/template and you'll find tyranids template for making kernel prx's. its called kprx_template and its what i used for my slim eboot launcher

just to clarify tyranid added the kprx_template just a few weeks ago because of the problems people were having making kernel mode prx's. So if you haven't updated your dev enviroment in a while chances are you won't have it

When did this happen? As far back as I can remember, to make homebrew for a non-1.50 kernel, your initial module had to be user-mode.

All plugins should be kernel mode and they work that way, but you can't loadexec an kmode elf in 2.x+ kernels. LoadModule works fine though

Meh. If I make my main module kernel mode, it never loads...
