I recently bought the Kirby Tilt and Tumble game for cheap, and I noticed something odd. Kirby always wants to roll forward, and you have to tip the game boy pretty far back to get him to stop. Left and right act as expected. Also, tipping the Game Boy forward barely, if at all, speeds him up. Is this normal for this game? I didnt get an instruction manual. And yes, I did level the game at the beginning by setting it on a table, so I know its not that.

I use an old SNES cleaning kit to clean all of my cartridges, but that is wearing out. I know I can use Q-tips. My question is, do you use alcohol with the Q-tips, and if so, what type of alcohol. Im afraid of using the wrong type, because NES games specifically say to NOT clean with alcohol. I imagine It could react with the plastic or something, I just want to be sure.
