Hi everyone, this is my first post, and I honestly don’t know much about how this system works. My brother had set this up for me, so I’m just kinda freeballing this. My brother had downloaded Launchbox for me and put Gamecube/N64 games on it. The one game on Gamecube I’m trying to play is the Spiderman Movie Tie In game. It starts up fine and everything plays smoothly… kind of. Once I load into the game and I take control, my screen constantly flicks between resolutions or the black bars on the side flicker from different variations on the screen. For one frame, it’ll go widescreen, then the black bars will be normal on the side, and then the screen will completely crush the image in itself. I honestly don’t know what to do or how to fix it. Any advice would be great.
