romdev-toolchain-m68k-gcc

m68k-elf-gcc toolchain (cc1/as/ld/objcopy/objdump) for Sega Genesis C — and the native m68k disassembler/reassembler behind disassembleProject — as WebAssembly. Plus SGDK's Z80 tools (sjasm/bintos), the Genesis C library tree (share/genesis/lib/: full SGDK + minimal runtime), and the full C build pipeline:

import { buildGenesisC, finalizeGenesisRom, parseBuildLog }
  from "romdev-toolchain-m68k-gcc";

const r = await buildGenesisC({ source: '#include <genesis.h>\nint main(){ ... }' });
const rom = finalizeGenesisRom(r.binary); // pad + $18E checksum (SGDK post-link)

One dep compiles everything for the target — an SDK or tool building Genesis ROMs needs only this package (romdev's own server builds through the same entry, so there is exactly one pipeline). buildGenesisC also accepts an injected env (runTool / share manifest / hash / sdkCache / loadGlue) so the identical pipeline runs in a browser Web Worker — see build/genesis-c/genesis-c.js for the contract.

A binary package for romdev: it ships the prebuilt WebAssembly + JS glue and is resolved by the main romdev package on demand. Install romdev for the full dev suite, or this package alone for the build pipeline.

Upstream & license

Bundles: m68k-elf-gcc, binutils.

License: GPL-3.0-or-later with GCC Runtime Library Exception (does not encumber compiled ROMs).

This package redistributes the upstream binary built to WebAssembly; the source is fetched from a pinned upstream commit at build time (see the romdev repo's scripts/versions.json and BUILDING.md). See the romdev repo NOTICE for the full third-party inventory.

Built by: romdevtools/scripts/build-m68k-wasm-tools.sh + build-sjasm.sh (no patch — built clean). See scripts/BUILD_MAP.md in the romdev repo for the full recipe→package map.
