Okay, I got this same issue with the japanese single layer. I don't have a DL burner, so, unfortunately, I have to stick to the single layer version. But, I'm getting DREs, A LOT. Other games work fine.. no DREs at all. But, with SSBB, as for the U.S. version, I followed the guide to make a fully playable SSE, and the game was working great for like an hour. Then, I rebooted my Wii (gave me a DRE, would not go away in stage 5 of classic mode), and I can't even get past the loading screen now. It just goes BOOM DRE. I reinsert the disc, but the screen just comes back.. I'm about to try another burn, but it can't just be a coincidence that it happened w/ JP version of the game as well? I have a Wiikey 1.9g, FW 3.2U Wii. I burned at 4x on TDK DVD-R (1-8x). It's pretty decent media, so I don't know? Thanks in advance! EDIT : Forgot to mention, the DREs aren't at exactly the same spots on the two versions. Hehe.
