This is an obnoxious answer, but Gordon Ramsay yells so much about everyone else getting Beef Wellington wrong, I’d like to have his Beef Wellington, but made by him under the exact same conditions where the contestants got it wrong, with no special privileges.
Just tried it, with a GBA Castlevania game (of course) and it handles beautifully. If this the future of AppStore allowed emulation, I’m a fan.
