Sorry I am using VBA-Next... I changed none of the settings. I just installed it and selected a game and the menu text goes a way, But the background stays. I have tried deleting it and reinstalling same issue. But if I install the old 1.03 one it works.
just tested that link with GBA game mario kart.. worked fine..
Do you get a black screen with a checksum error at the bottom?
If so hit R3 and then you have options force to PAL or NTSC .. try one of those i has an issue awhile back with one of the versions in the past.
