DDR 1st Mix: static recompilation and freeze analysis

DDR 1st Mix recompiles the PlayStation release SLPM-86222 by translating its MIPS code to C with PSXRecomp and building a native executable. Game-specific hooks address runtime behavior, and the author documents tracing an animation error into a cyclic display list that caused freezes.
