- Buttons are unresponsive at initial game setup, you need to hold the yes/no button
until it responds. The keypad reading routine is at $1A5D, it gets skipped for several
seconds at a time. Once in-game, everything is fine though. BTANB or different cause?
- get rid of savestate workaround once outputs support savestates
