Used Goomba Front to create a GBA game out of the GBC game.
Generated a new save file for the GBA game which was 32KB.
Named new empty saved file GBA.sav
Named GBC save file GBC.sav which is 8KB.
Used tool above to inject GBC save file into GBA save file, ended up being 64KB but after opening it with the VBA changed back to 32KB with my 8KB save file data.
