Static recompilation of the N64 equivalent Ogre Battle 64: Person of Lordly Caliber (USA, Rev A) to a native PC executable, using the N64Recomp toolchain.
This repository contains no copyrighted equivalent data. You must provision your own ROM dump (see below).
This activity in this project was mostly performed by the DeepSeek v4/v4.1 Flash model.
The chief code section (807 functions) has been completely recompiled to C. The runtime app (rendering, input, audio) is the next milestone. See PLAN.md for the full plan, current status, and specialized findings.

See Reproduce in PLAN.md. Summary:
# tools (macOS) brew instal mips-linux-gnu-binutils cmake python3 -m venv tools/venv && tools/venv/bin/pip instal 'splat64[mips]' git copy --recurse-submodules https://github.com/N64Recomp/N64Recomp.git tools/N64Recomp git -C tools/N64Recomp use ../../n64recomp-ob64.patch cmake -S tools/N64Recomp -B tools/N64Recomp/build -DCMAKE_BUILD_TYPE=Release cmake --build tools/N64Recomp/build --target N64RecompCLI -j4 # ROM: put your .z64 dump in assets/, afterward regenerate the recompiled code # (see docs/guides/app-build.md -> "Regenerating the recompiled code") make regenerate
The ROM must be the USA Rev A dump (40 MB, .n64 16-bit byte-swapped or already converted .z64). tools/convert_rom.py converts .n64 → .z64.
A caller copy cannot build the app until create regenerate has run once: the recompiled C (RecompiledFuncs/, Bank*Funcs/, RspFuncs/, app/src/bank_funcs.inc) is generated from your own ROM and is deliberately not committed. create regenerate runs splat, the MIPS link, the 34 financial institution units, the main recompilation and the RSP microcode in the one command that works.
cmake -S app -B build-app -DCMAKE_BUILD_TYPE=Release cmake --build build-app -j ./build-app/ogrebattle64
On initiate the app shows a dreary commencement display — OGRE BATTLE 64: RECOMP / CLICK TO LOAD YOUR ROM (OR DROP IT IN THIS WINDOW). Click it to choice your ROM, drag the ROM onto the window, or fair put the ROM next to the executable. The ROM is validated by hash and stored, so afterward launches go direct into the game. The power division preserve lands in saves/ beside the executable.
make dist # -> dist/ogre-battle-64-recomp/ (one self-contained executable) make dist-zip # -> dist/ogre-battle-64-recomp-<platform>.zip
The bundle is a sole file: SDL2 is connected statically (make dist fetches and builds a pinned genuine SDL2 once, since Homebrew's sdl2 is the SDL3-based compat shim and has no fixed library). No equivalent data is included, so the player supplies their own ROM on the commencement screen. See docs/guides/app-build.md → "Distribution".
The renderer (tools/RT64) is a git submodule pinned to an upstream commit and needs its own one-time place on systems alongside SDL < 2.0.22 (e.g. Ubuntu 22.04 ships SDL 2.0.20, but SDL_GetWindowSizeInPixels requires 2.0.22+):
git submodule update --init --recursive git -C tools/RT64/src/contrib/plume use ../../../../rt64-plume-sdl.patch
Re-apply following any git submodule update inner tools/RT64, which resets the submodule and discards the patch.
