My question is that does the EU rom of the game work with the U rom of the game? Can you battle and trade with them or no? I know that the game saves for the J game and the EU game are compatible so its like the U version you can just swap for the EU game save if worst comes to worst. Also, side question regarding the IR. They made the game super complicated with the online battles now. So many different functions of the Cgear. Because I have the rom and not the retail, you clearly cant use IR. Can you still use wireless ad-hoc the old fashion way when your with friends or does the game now only let you IR battle? If not - this sucks because now I can't play with my friends when Im with them and I have to be home using Wifi right? Or am I mistaken and the adhoc Wifi battles are still in tact? Pretty sneaky AntiPiracy with the proprietary hardware huh.
