Hi!
I have on the screen a mixture of the Dot Cross Hatch bios and the weird game
https://www.youtube.com/watch?v=DGqm4yK58Rg
as soon as I raise the side of the PCB to the right where the big crystal oscillator is, the bug is gone.I redid a lot of welds and now it's worse, the problem remains constant now
The really weird thing is that I removed the 2 dip switch and it worked for a while.I don't know if it's a broken track or a dry solder.Thank you for helping me
