Hello,
After I fixed the sound and the oscillator crystal the board worked for some time and now all it displays is this:
989c4446-39c5-4a82-9b91-da4e3e22f102.jpg
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! :)
 
After some testing and visual inspection I kind of lost hope, it revived itself after I changed some dipswitches from their position and back. Go figure these boards sometimes. :)

My initial problem of the sprite errors has to do with the voltage drop, as I use a supergun with an ATX power supply I can't change the voltage, how could I manage this issue?
My supergun only has a 24 pin connector for power, how could I connect a variable arcade PSU to this 24 pin connector?
Thank you.
 
Hey there people! I bought a Mean Well PSU and basically cut the cables and the 24 pin connector from the ATX and plugged the necessary cables to the new arcade PSU and all is solved, including the TOKI sprite errors! :)
Hopefully this can help other people in this matter, it was due to the low voltage to the sprite ram that was in the end of the second board, a bit more juice and there she goes!
Thanks everyone!
