So, it looks like my SNES with a SHVC-CPU-01 motherboard is starting to have problems. Went to test it on my new TV and no picture with Super Mario All Stars, just a black screen. Then I insert the Super GameBoy and oh a picture, scrambled graphics, but audio and a picture. The pixelated mess would change colours from blue to brown to yellow to red depending on what was happening with Pokemon Yellow Version, and the audio was crystal clear on all signals RF, Composite, S-Video and RGB. I tried cleaning the cartridge connector but that didn't solve anything. Being I always had a problem with Super Mario Kart not being able to show the bottom half of the screen with the track, but the top is just fine, and I did test it on another SNES, it was perfect, could it be one of the PPU's or RAM chips going out?
Once I get the equipment and materials needed, I possibly may or just sell it as a scrap board, still weighing my options.
