    Hi guys, I have an SNES launch model from 1991 with a UN10 serial number which works and turns on, but i have a problem with WWF Royal Rumble and Aladdin in MK1. They glitch on the Title Screen and in MK1, I get a small glitch such as black small lines on the character shadows. I'll show you the glitch. And no the games are not the problem. I tested them in a SNS-101 Mini Jr and they are glitch free. Here is a video:

    Are SHVC CPU 01's proven to be the most unrealible SFC/SNES out there?
    Is my PPU, CPU, RAM dead or my board has bad traces?

    What is cauing the cpu or ppu to die? I tried many different 62 pins and sound moudles and i get the same result. If anyone has a new SHVC-CPU-01 board for me, PM me.

    I would start by replacing the 7805 voltage regulator, and the caps. Also make sure you're using the correct power supply for the SNES.

    I tried different power adapters and get the same result. I'm using the correct power supply.
