PCSX-Redux SupportPSX library

This library contains a few functions that are used by the PCSX-Redux emulator. It is a collections of standalone functions that are not specific to the emulator itself, but are aimed at being used in the context of the PlayStation 1. The library is written in C++ and is meant to be used in a pick-and-choose fashion. The library is not meant to be used as a whole, but rather as a collection of functions that can be used in other projects. Some pieces are header-only, while others require compilation of some C++ files. Usually, if compilation is required, it will be with the same base name as the header file.

Very little external dependencies are required. They will be documented in a per-file basis below.

Contents

• adpcm.h & adpcm.cc - Provides a simple ADPCM encoder. It is a re-creation of the original encvag.dll from Sony's development kit for the PlayStation 1, and is meant to produce similar results with a similar API.
• binloader.h & binloader.cc - Loads a PlayStation 1 binary file from a File abstraction to another File abstraction. The binary file can be of the following formats:
  • PlayStation 1 executable file (needs the "PS-X EXE" signature)
  • ELF
  • CPE
  • PSF
  • MiniPSF
• iec-60908b.h & iec-60908b.cc - Provides iec-60908b helpers and encoders for MODE2 discs, such as the ones used by the PlayStation 1.
• ps1-packer.h & ps1-packer.cc - Provides a function to pack a PlayStation 1 executable file into a self-decompressing executable file. The resulting file can be loaded directly into the PlayStation 1 memory and executed. Supports multiple encoding methods.
