Next implementation steps:
1. Inspect visible startup/menu progress and exercise input in the bounded local game run. Record the first demonstrated failure.
1. Visible startup/menu progress is established: attract mode reaches the start menu and Birch dialogue, and sparse taps reach the in-game start menu by 12,000 frames ([probe](research/emerald-visible-progress.md)).
The first demonstrated second-game failure is a boot-init halfword store to ROM mirror `0x09fe2ffe` (recorded, not fixed).
Use original regressions for any hardware correction; do not invent connected serial devices.
2. Validate an external game's completed save/restart/load cycle using a disposable `--save-file` path.
Refine nominal Flash timing and polling only with independent evidence and original regressions.
