Case study

MegaManZeroRecomp: statically recompiling Mega Man Zero

MegaManZeroRecomp statically translates the Mega Man Zero USA revision 0 ROM, SHA-1 193b14120119162518a73c70876f0b8bffdbd96e, from ARM and Thumb into native C++. The runtime hash-gates the ROM. The ROM file is roms/megaman_zero_usa.gba. The repository is cloned beside gbarecomp, gba_recompile regenerates the translation units, and cmake --build build --target MegaManZeroRecomp builds the Windows program.
