I'm fairly new with flash carts, but I've been using this one for about a month now and have had no problems, but today I wanted to go and play Mario 1 on it since I currently don't own a copy for the famicom. However running it simply takes me to a black screen. I've tried roms from a few different sites and have even tried using the FDS version and I still get the same effect (it says to set the disk then goes to a black screen). Anyone got any clue how this is happening?
