TMC v0.2.1-experimental

Highlights since v0.2.0

• macOS asset pipeline rewrite (PR #60) — 60s extract+load worst case, ~1s warm; binary + ROM is all you need now (no separate extractor). macOS arm64 + x86_64 (Intel) builds.
• GBA build restored — make build GAME_VERSION=USA produces a byte-identical tmc.gba plus tmc.elf with debug symbols, useful for debugging via mGBA + arm-none-eabi-gdb.
• #93 Vaati takeover partial fix — cutscene now plays through dialogue and the save state correctly advances past the softlock. Camera-pan and post-cutscene render still need work; tracked as a follow-up.
• xmake auto-applies viruappu-widescreen.patch — fresh checkouts get mode1 (Hyrule Town BG) parallel rendering on first build.

Known issue

• macOS x86_64 (Intel) build is queued in CI but the macos-13 runner pool is slow to allocate. The artifact will be appended to this release once it completes.
