Re: Wrong SNES video
I already replaced both video RAM memories and nothing continues the problem. Thank you
Re: Wrong SNES video
What is more likely that the failure is in the PPU1 or the PPU2?
Re: Wrong SNES video
And the working RAM of 128K, I have not replaced this, could it be the cause?
Re: Wrong SNES video
Here I have the electrical diagram of the snes. It is seen that PPU1 is the one that addresses the video memories and not PPU2.

Re: Wrong SNES video
I have one SNES where PPU1 went bad one day all of a sudden and I have heard many other reports of bad PPUs in SNES, so it isn't unlikely that this is the problem especially since VRAM has been changed.
