What this is
We're rebuilding X Plus from C on two discs at once: the Japanese release (SLPS-20137) and the Korean release (SLPM-64525). A function only counts once its C compiles to the same bytes as the disc on both. Every 30 minutes the work is checkpointed, and it only reaches main after full builds of both discs come out byte-identical.
The Korean disc kept its debug symbols, so every function has its real name and types. That's why X Plus goes first: matching runs about twice as fast, and what we learn carries over to Accent Core.
Done so far
- Sol, Ky, May and Millia are fully matched.
- Hitboxes, Tension, throws and the CPU AI are largely in C.
- 62 of 126 source files match completely.
Up next
- The last 265 game functions: modes, rendering and battle code.
- Moving the data (move tables, hitbox tables, strings) into C too.
- The Sony SDK libraries, counted separately.
