zig port of my prototype replay verifier was done in roughly 15 hours. it required porting a large portion of deterministic gameplay core. zig version could clear its first replay while the rust version is nowhere close from being done. zig version runs 5x faster than python.

@philogy interesting, after more updates it became roughly 56x faster than python, that's more in line with my expectations. i got about 0.0175 ms/tick.
