I can confirm that rev101 works perfectly, loading all of my covers and disc images.
The gfx options is neat, though I wish there was a way to make it compensate for a widescreen TV so discs and covers aren't stretched too wide. (At least, I don't think any of the options seemed to do that, it's impossible to read them over the top of the covers so I was really just messing around). Hopefully that'll come in later versions? And also, I'd suggest a "Reset" option for those. Oh, and also the buttons to switch the languages, the spot where you click doesn't line up with the buttons on screen. (In fact, all of the buttons for the config seem to be just slightly off on my screen, but I assume that'll be cleaned up in future versions).
And as great as it is, once this is finished will there be any possibility of a child-proof version that removes the settings and delete buttons? While it's in such active development as it is now, two versions would be a pain, I hope that eventually there will be one.
But honestly, it's perfectly usable as is. Visually all this really still needs is a (single, in my opinion) background image, and maybe just slightly slower rotation of the disc art. I've now gotten rid of the old loader that I'd been using and have switched to this full time.
And one other thing that might be nice for future versions that isn't quite necessary might be a cursor for when the pointer isn't aimed at the screen, but again, that'd just be an added bonus.
Again, great work to everyone involved. This is amazing how fast this has really moved forward.
Edit: Oh, and since I'm using a forwarder, the option to go back to the Wii menu as opposed to the homebrew channel would be nice.
