It has been a few months since I used my Super Everdrive much, and once I finally got my SNES set up again I went to play some games and was greeted with this:
Waves of interference lines constantly moving across my TV.
For most of the day I thought I might have broken my Super Everdrive somehow, as I am the "if you can't open it you don't own it" type and had removed it from the nice shell provided by Stone Age Gamer several times. I even went so far as to try it on two separate television sets as well as my Super Famicom (which has a video chip that is going bad, it only made it look worse). No change.
Then, I realized that something had changed since I last used my Super Everdrive for more than a few minutes. About two months ago I bought a Killer Instinct cart and had transferred it to that shell with a low profile MMC card. No offense to Stone Age Gamer, I just don't really like the way the Universal shell fits in a North America SNES.
So I popped in the SD card that originally came with my Super Everdrive, and everything is working fine again.
I just thought I would let everyone know in case they ran into this same issue.
I am just left with one question: Does anyone know where I can get a good quality reduced profile / mobile MMC in the States? I spent $12 on this one and it turned out to be quite the dud.
