5thPlanet

A disciplined workflow for tracing hard / stubborn bugs in the 5thPlanet Saturn emulator without tunnel-visioning — classify the failure, make it deterministic, write the hypothesis with explicit falsification, win by register-completeness + an EARLY oracle diff, instrument the transform's OUTPUT, ALWAYS fan out to multiple parallel agents with competing hypotheses, and run a self-check tripwire when probes stop narrowing. Use it for LLE fidelity gaps (render / audio / timing / boot), intermittent stalls, "random" crashes, and any bug where the first few probes haven't eliminated a cause.

Dump a physical SEGA Saturn game disc to a 5thPlanet-loadable CUE-BIN image, using redumper (preferred) or cdrdao (handling its MSB-first CD-DA byte-swap gotcha).

Manage the full software release process for the 5thPlanet workspace — version bumps, changelogs, Git tags, and (when applicable) GitHub releases.

Perform a project-wide code review of the 5thPlanet SEGA Saturn emulator, covering correctness, emulation accuracy, code quality, tests, documentation, and style.

Audit and update all project documentation to stay in sync with the current development status of the 5thPlanet SEGA Saturn emulator.

Profile and analyze the performance of the 5thPlanet SEGA Saturn emulator end-to-end — from the SH-2 interpreter core through the VDP2 compositor to the SDL2 jupiter frontend — then report concrete, accuracy-safe optimization opportunities.

Stage, commit, and (when a remote exists) push changes with a well-formed Conventional Commits message.

Perform a project-wide security and safety audit of the 5thPlanet workspace.
