Mega Man Legends 2 0.1.0 — setup package
Platform: windows-x64

One zip for first install and updates. Does NOT include disc images, retail
BIOS dumps, pre-generated game C, or a bundled build-tool pack. Emitters
(psxrecomp-game / psxrecomp-bios) and the CLI are inside psxrecomp/.
Standalone:
1. Install Python 3.
2. Run Mega_Man_Legends_2.
3. Provide your legally owned Mega Man Legends 2 (Europe) disc and your own legally dumped SCPH5552 BIOS image (required; OpenBIOS is not supported by this title).
4. Follow the Generate & rebuild wizard. On first rebuild the host downloads
   cmake-clang-v1 from RetroPortingToolKit/RetroPorting-Toolchains (or you can
   pick a local cmake-clang-v1-*.zip for offline builds). System cmake/ninja
   also works if already on PATH.

Retro uses this same zip: it harvests emitters into a shared SDK cache,
downloads the toolchain pack (or uses RETCOMM_TOOLCHAIN_DIR), and preserves
saves/user config across updates.

Diagnostic mode (if the game crashes, freezes, or misbehaves):
- Setup builds two products: build-release/ (normal, the default) and
  build-diagnostic/ (debug server, freeze heartbeat, freeze dumps).
- To switch, create an empty file named diagnostic-mode.txt next to
  Mega_Man_Legends_2 and start the game as usual (or run Mega_Man_Legends_2 --diagnostic).
  Delete the file to go back to normal mode.
- Reproduce the problem, quit, then run Mega_Man_Legends_2 --collect-diagnostics.
  It writes diagnostics-<date>.zip next to Mega_Man_Legends_2: attach that file to
  a GitHub issue on this title's repository. It contains only the runtime's
  report files (never saves, BIOS, or disc images).
See psxrecomp/docs/DIAGNOSTIC_MODE.md for details.
