I recently ordered a copy of Super Mario Bros. 3. When I put it in the NES, the screen flashes purple and black and the power light flashes as well. I have attempted to clean dust off of the cartridge, and the NES works fine with other games. I don't know what to do next, please help!
If I push the cartridge harder into the NES, I can make it so that the screen is a solid purple and the power switch isn't blinking. Game still doesn't work. Still need help.
