In RC5's preview, I'm still having the issue I mentioned where the wrong covers are being displayed at times in 3d mode. I've got like 85 games installed though, so it might be a memory issue. The cursor corruption appears to be fixed, but I'm getting another issue that I haven't seen in a while, where part of the cover image for a few games is obscured by what looks like 'snow' on a TV with no signal. I assume that's again an out of memory-type issue, because when I scroll to the opposite side of the list and then back, it's fixed.
I mentioned this earlier, but if you end up not being able to optimize better to have more memory available in 3d covers mode, then I'd suggest a third mode that keeps the 3d boxes and the front and side, but disables loading the back cover and the flipping of the box. I'd assume (maybe incorrectly?) that this would allow for double the amount of games?
