Ok, so what cheats could I use to, say, duplicate berries?
There aren't that many good AR codes out there for RSE/FRLG games.
And would this work for combining VBA and EZ3in1?
Play game in EZ3in1. After you're done playing, save the game and transfer save file to computer.
Open game in VBA, check Real Time Clock, and change system time one day forward.
Put save file back in EZ3in1, then change system time one day back to normal.
