A matching decompilation/build of Mario Golf 64 (N64, North America — NMFE, rev 0). The build reproduces the original ROM byte-for-byte: undecompiled code is re-assembled from baserom-extracted assembly, and decompiled libraries are compiled from C/asm in src/. Libraries land on master one commit at a time.

Requirements

• The original ROM at baserom.z64 in the project root (SHA-1 e2c4e7a905b29529b49a1619a401fe699224829b). It is gitignored and never committed.
• mips-linux-gnu binutils (supplies cpp, as, ld, objcopy, strip).
• python3 with venv.
• wget (to download the KMC GCC 2.7.2 + binutils 2.6 toolchain during setup).

Build

make setup     # create venv (splat) + download the KMC toolchain into tools/cc
make extract   # split the baserom into asm/ + scaffold with splat
make           # build build/mariogolf64.z64 and verify it matches the baserom

tools/verify-rom.sh runs make and asserts the OK line before trusting the ROM SHA-1 (the build's stale-ROM guard). CI (.github/workflows/build.yml) runs the same setup -> extract -> verify flow in the container defined under docker/.

Layout

• mariogolf64.yaml — splat configuration (ROM layout + per-file subsegments).
• src/ — decompiled C and vendored hand-asm. include/ — headers.
• mk/ — per-tree compile rules included by the top Makefile.
• symbol_addrs.txt, reloc_addrs.txt, hardware_regs.txt, extern_syms.txt — splat/link inputs.
