From what I know, if you have a DSi (or DS enhanced game) you can't play it on a DSi (or DSiXL) that is from a different region. You have to have the game and the system of the same region to play. With the upcoming Pokemon games, some people won't be able to play the japanese versions. Whether they import and use backups, since it's the JAP release, it will be useless in US handhelds. My question is: is there any patch, fix or workaround to play different region games here?
