Aidyn Chronicles Decompilation

Decompilation of Aidyn Chronicles: the First Mage on the Nintendo 64.

Why this game?

Aidyn Chronicles is one of a handful of RPG's on the system and a relatively obscure title. As such it's inner workings fascinated me. It led to the discoveries of the workings of the system, such as cheat codes, turning enemies passive on the field, and randomized battle encounters. since then, my interest grew to fully understanding the game.

What this contains:

• Splat yaml's for Debug and another one for NTSC 1.0.
• symbol tables for both.
• src_pseudo/ : untested code of the source files based largely on the debug build interpreted by Ghidra and cleaned up by hand (apart from libultra files - they're largely unchanged, AFAIK)
• include/ : header files
