    After succesfully modding my first 1CHIP SNES with a lockout switch and 50/60hz switch (http://www.assemblergames.com/forum...C-and-mod-help&p=733725&viewfull=1#post733725), my second attempt has met with less result so far unfortunately :(

    I'm getting heavy graphic glitches as can be seen in the pic and video. Anyone got any idea where I should look? Only real trouble I had again was getting the PAL crystal off. Can this be a crystal issue? Or is it likely in the S-CPUN A? (or something else?)


    EDIT:
    Btw, this is for both composite and RGB output.

    Checked everything with a multimeter, seems no issues there. Soldered the crystal back in the original place, no effect either. Will try to get everything back in the original state as much as possible and say my prayers

    EDIT2:
    Hooked up 5v directly to pin 111 and tried both a PAL and NTSC crystal on the original spot; still the same issue.
    Trying to clean the cartridge slot.

    EDIT3:
    Cleaning the cartridge slot didn't have any effect.
    I soldered both 5v directly to pin 111 with the PAL crystal in the original spot and ground directly to pin 111 with the NTSC crystal, still the same issue. I even tried it without pin 111 connected, but then the image is even more garbled, and the system crashes after a little while.
    I'm really beginning to think this SNES has died on me :(

    EDIT4:
    Wonder if it's kinda the same problem as GlitchyGhost here
