1. Make sure that the latest .romdata files are present.
2. Run the emulator, and load Sonic the Hedgehog Game Gear.
3. Verify that the emulator switches into "Japanese" mode.
4. Start a game. Note that the level preview screen closes automatically
and Sonic jumps in the air without prompting.
From this point on, you cannot jump - it looks to me like the controller
buttons are stuck down.
This only occurs when the game is detected as Japanese.
I suspect that the controller port bugs are to blame. Region detection is
handled by port 0 on the Game Gear - check that controller ports show
similar Japanese/Export quirks when in GG mode?
