Aren't those the romhacks based on another series called Keitai Denjuu Telefang? Because if so, that'd be fun, since Gachasute was made by Smilesoft and Rocket Compnay, which made the GBA Telefang games (official ones, not the romhacks :p).
Though I'm not sure it'd fit the "GBA" category...
And thanks! Next episode won't be that soon because I'll have to manage my money (because university), but I promise to do another one!
