Hello,
After I fixed the sound and the oscillator crystal the board worked for some time and now all it displays is this:

Been searching around for information on this matter with no success, anyone has an idea of what could have happened?
The game was working, froze, and then this happened and won't go past this,
I'm using a supergun and it works with all the other boards I have.
Thank you!
