God, how I hated the Nintendo hardware.
Load a cart, power on, see the vertical scrolling white screen, power down, take the cart out, blow across the ROM, re-load, re-power, see the vertical scrolling pea-soup screen, power down, blow harder until you spit, reload, see the actual game only to realize it\'s resetting itself over and over, power down, BLOW UNTIL YOUR CHEEKS TURNED RED, CURSING NINTENDO, then finally being able to play the game. Only problem is, now the game is severely pixelated and constantly dithering.
We had this solution. We took the pocket all the NES games in and jammed it in to hold the cart down. Worked when all else failed.
