If I did understand correctly, the 3 in 1 expansion pack can simulate a GBA-game almost perfectly, even to a point where a original Pokemon Pearl would recognise it as Pokemon Ruby for example and unlock the special Pokemon in certain areas. If that's correct I'm deffinatly going to get one. The only question that remains is wich Slot-1 device I should get with it. I'm not exactly new to the DS-backup-modules, but I seem to have lost track with the Slot-1 ones (I still have a M3-CF). As far as I know all things that the EZ V can do with the 3 in 1 Expansion Pack can be done with other Slot-1 devices and homebrew. Since the combo of the Pack and an EZ V and the combo of the pack and an R4 are about the same in price over at bamboogaming it really only comes down to the Slot-1 cards. (Even so I'm a little displeased that the R4 doesn't come in black anymore. Nintendo employes will see from 30 fett away that I don't have an original card in it. [I will get the original game, but imo it's nothing wrong with getting a few additional Pokemon ]) So is one better than the other? And wich things make it this way? I hope you can help me. Thanks in advance.
