So i bought an R4 card for my girlfriend from http://www.r4i-sdhc.com. I loaded quite a few games onto it and it works pretty well, the firmware i used is the one right there on the homepage of the site that is said to be what they suggest for my card. i have a few issues however, one is i cannot access the cheat menu, such as quicksave options. the other, and this is the big one, animal crossing: wild world will fail after a while. my gf loves this game but after she gets through all of Tom Nook's stuff and saves, she loads it up and it will just white screen and never move on to the actual game...Did i mess things up? Can i put a better firmware on the card?
