That´s funny. Check my situation, maybe we can come to some sort of solution.
Wii US 3.4 modded with Wiikey
For more than a year, all games working fine.
Using ridata dvds for the most part.
3 months ago, started the first DREs. Assorted games.
Noticed that in some cases, the dvds itself started to rot. Burning again in a new dvd solved the problem.
In other cases, the DRE problem kept going.
Now, the present state of my DRE problem got me some conclusions.
1) Some games work.
Animal Crossing works. Flawlessly. After burning 3 copies and PROTECTING this last copy, the game is running for the last few weeks without ANY DRE.
Guitar heroes and rock bands works. No problems at all. Hours and hours playing non stop.
Samurai Warriors Katana is working fine. I know is stupid, but my brother likes the game (and it is an old burn! From the release date!)
Other games working too, No More Heroes, Manhunt 2, Mario Kart... old burns, working fine.
2) Some games DOSENT work. REALLY DONT!
Resident Evil, Umbrella Chronicles: For months ive played the game. My brother came for the holidays and loved it. The game was solid, but started to show DRE after some time.
Burned FIVE copies of RE: UC. 2 from the original disk, 3 from a new download. Sometimes the games dosent even get recognized. Sometimes it starts... then DRE.
Other games showing the same symptoms: Dragon Quest, Excite Truck, Smash Bros (an old burn, im not buying DVD 9 to try it out again..)
Game Cube games: no dice. All get recognized, starts, then DRE
3) Just for the sake of curiosity...
Wiikey config DVD dont work anymore. But i guess it has something to do with the 3.4 uptate....
4) What am i going to do about all this?
Well, i wasnt going to do nothing...
But i saw at Play Asia that wii cleaning kit...
Ive ordered last week. Still waiting...
Call me stupid (go ahead), but i think this might solve the problem...
