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!

Comienza revisando el sitio web actual y los Makefiles existentes que, según indica el issue, los lectores deben inspeccionar. Investiga el flujo de trabajo de build y dynamic-loading de PRX en torno a psp-build-exports, psp-ar, psp-fixup-imports y las llamadas al sistema indicadas. El trabajo estará terminado cuando el sitio web tenga una guía coherente que cubra los temas solicitados sobre build, carga, bibliotecas stub y restricciones de módulos.
