Up to a few weeks ago I was using a Swap Magic set to play backups and import games on my PS2. I got tired of that pretty quick, though, so after asking around a bit I came to the conclusion that the Magic 3.1 would be an ideal modchip for me (since I'd only use it to play games) and got one installed. Unfortunately, my backups don't seem to work. I tried a few DVD-R backups that used to work with the Swap Magic, but most of the time the PS2 won't even detect the game and when it does, I get the red screen with the "Insert PS or PS2 game disc" message. I took the PS2 back to the installer, and he tried it with a copy of NHL 2002 he had backed up on a Verbatim DVD-R. It booted perfectly. When we combined this fact with my ability to play PS1 imports and backups as well as PS2 CD-R backups, we came to the conclusion that the modchip was working. Now, as far as I can see, this leaves two solutions. 1. The laser unit is borked. It's making awful noises and even my original games are loading much slower than they used to be. To add credibility to this theory, I noticed my DVD movie backups weren't playing either. I'm currently using Bulkpaq DVD-Rs I bought for general use. 2. The Magic 3.1 is in fact a worthless piece of crap and won't run most backups (this is the installer's theory). I tried with Manhunt, Devil May Cry, Devil May Cry 2 and Onimusha 2, all of which SHOULD work with the Magic 3.1. I'm personally leaning very strongly towards the "dirty laser needs cleaning" theory. The awful noises the PS2 is making combined with the fact that my Swap Magic set usually required up to 10 reboots to get it working would lead me to believe the laser on my old V3 needs urgent adjusting and cleaning. Before I start poking around my laser unit again (I know how to do it, but it's a bit of a hassle), what's your theory? What I'm mainly looking for here is messages from Magic 3.1 owners saying "No, dude. Those games should work." to reassure me.
