hi, Merry Christmas!
I just tried GDEMU and OpenMenu, it's fantastic. But i have to solve several issues:

1) All Atomiswave port don't work. Cover and description are correctly detected, but when i launch the game, it appers this screen: https://i.postimg.cc/vHCTMq7b/IMG-3214- ... imizer.jpg
I tried these games:
1) Dolphin Blue
2) Force Five
3) KenJu
4) Knights of Valout the 7 spirits
5) Rumble Fish
6) Rumble Fish 2

Please, can you help me?

thanks!
