Need help with Ruby, Sapphire, and Emerald

Im using a dingoo A320 for my gba roms and when i try to start the games all i get is a white screen for all three. Does anyone know what i could do to fix this?

I've heard of something like that before..But do you have to patch the roms in order to play them?Check with your manual if you got one or look it up on the manufacture's website.

i dont have to patch anything. I just have to put the roms in the folder. The games show up but when i start them the screen goes white.

Follow this tutorial, and you will be able to play them on VBA.

I see you aren't using VBA, sorry. Well, these games require special fixes on good emulators. Your little handheld device may not work correctly with them.
