Hey,

So I built a mapper 4 game and tried it on a TLROM and a TSROM board. The game boots up and works but has garbled up graphics on both boards. I first tried the TLROM board and when I saw the garbled grpahics I just thought it might be cause it needed ram so I switched to the TSROM board but I'm still getting the same results. Any ideas?

Cheers!

Tell us what game it is.

Street Fighter 12 peoples. I was able to figure it out on my own, I had A16 of the CHR floating as I had the pin up instead of attached to the pcb.
