I recently finished a playthrough one of my favorite GBA games, Sigma Star Saga, on my A320. Aside from player movement in the RPG segments seeming a little slow, the only major problem with the game on the Dingoo GBA emulator is that the emu state saves sometimes get glitchy, resulting in bugs like insivisble status an ddialog boxes. I find that, to avoid this, save immediately after shooter segments (I usually save righ tafter the "Stage Cleared" screen) ... and save often. In-game saves work, but state saves let you save your progress more often and with more control.
Has anyone successfully run "Big Mother Truckers" on their A320?
