So i built another Virtualtap and i’m getting the same result as the other. I’m still seeing lines across my screen. I tried reflowing all the chips on the Virtualboy but that didn’t change anything. My next step is probably tracing the board with a meter to see if i can find any broken tracers but it looks it looks in good shape. For additional information, i’ve only tried 1 game, but i think i see some lines on the intro and i’m using a Jaguar PSU.
