Add PRX/Stub Library Example/Guide

Dynamic Link is an essential part in PSP Programming. It's also the foundation of PSPSDK and CFW. However, current website doesn't include such guide on how to write export table, generate .S stub etc. One has to dive into Makefiles to figure out the complete process.

I'd like to add a guide to the current website that includes:

• How to build PRX for others to use

  • How to write C code for PRX program (module_start/module_stop)
  • How to write export table
  • How to use psp-build-exports -b to convert export table into C code
  • How to write correct Makefile (-nostartfiles flags etc)
  • How to generate .S file using psp-build-exports -k
  • How to generate .a Stub Library using psp-ar

• How to load PRX dynamically

  • System Calls such as sceKernelLoadModule, sceKernelFindModuleByUID, sceKernelStartModule (? Not quite familiar with this part)
  • What .S file does and how psp-fixup-imports works

• Other Topics

  • Kernel Module / User Module(?) Calling Constraints(?)

Looking forward to your suggestions!

Inizia esaminando il sito web attuale e i Makefiles esistenti che, come indicato dall’issue, i lettori devono ispezionare. Studia il workflow di build e dynamic-loading di PRX relativo a psp-build-exports, psp-ar, psp-fixup-imports e alle chiamate di sistema elencate. Il lavoro è completo quando il sito web contiene una guida coerente che copre gli argomenti richiesti relativi a build, caricamento, librerie stub e vincoli dei moduli.
