Zelda 4 sword adventures: I see the nintendo logo and then black screen.
Wind waker: I'm able to load the game in swiss but then right after I start it, it says "an error has occured. Please shut the power off" blah blah blah.
Paper Mario the thousand year door: I'm able to play it but after like 5 minutes the music will stop looping and I get the same screen as wind waker.
Smash bros melee: exact same thing as wind waker except in smash bros font

So, does it sound like I need a pot tweak? I have a model "DOL-101" and my friend told me you don't need to pot tweak them. I thought my discs might possibly be bad burns but I used nintendont for the wii and hit boot disc from drive and ALL the games worked flawless. All help and ideas would be apprechiated!
