Wrong save type used for Pokemon Fushigi no Dungeon - Aka no Kyuujotai (Japan)

[Lesserkuma]

The game Pokemon Fushigi no Dungeon - Aka no Kyuujotai (Japan) (AGB-B24J-JPN) requires the Flash 512kb save type. By default, mGBA uses the Flash 1Mb save type for it, resulting in not being able to save.

The game’s error message reads きろくできませんでした (= Save failed).

Tested using mGBA version 0.11-8008-a06430691.
