I'm having some stall issues with the English versino of Final Fantasy 4. After I have gotten the twins my battles lock up almost every other fight. All I get is a double white screen and that's it. I am using an r4 with 1.18 (English) firmware using a US version of the rom. while I did have some issues earlier with the mini-game not resuming with the ds closed, I had no other real game issues before this. I am not using any cheats, I don't have any cheats at all for this game. Anyone have any advice to get over the bump?
