1. Provide Flash Save ROM file for GBA

The GBA version was previously available only as a ROM file for the FRAM/SRAM save method, but we have added a ROM file that supports the Flash save method.
If you wish to play the game on a real machine, please write the ROM file that is compatible with your Flash ROM cartridge.

2. Bugfix of GBA sound procedure

Fixed a bug that caused incorrect sound effects to be generated at unintended times when running the GBA version on the Revo K101+ compatible device.

I have not seen this problem on the actual device and mGBA, but this is due to a bug in my sound driver, not a K101+ special correction.
