Did you have a chance to do this? I can also test it out if someone can explain how to convert it to be darksoft ready.I'm traveling now but when I get back, I'll try and play a single player game all the way through to the end.The version I had of Random stages crashed in 1P mode after the third match IIRC. It black screens and has to be reset by going to the test menu and returning back to game.
I can try this one as well.
EDIT: Nevermind, it's for a decrypted game. Mine is still running on battery.
