Hiya,
Big fan of the SNES9x GX, it's my most used app. I have only one problem with it: The game titled -Godzilla: Kaiju Dai Kessen- doesn't work correctly. After you select your monster and your foe, the game stops during mid-transition between the map screen and the actual fight. You can still here the menu BGM and return to the main menu and whatnot, just you can't go any further than that.
