OK, WIP 1230 has been posted.
The image stuff, hopefully, is all working now.
Kludgy as hell, since the Xbox libs create textures differently, apparently, between blanks and loading from a file, though there is no way for the programmer to find out, since those interfaces are not exposed.
I've also incorporated preliminary games db dsupport. Go ahead and update your gamesdb.xml file (via ActionScript, since MXM will save out it's stored gamesdb when launching an app). It also tracks launchcount and launchtime. I will probably add those into the menu system when I get a chance.
In the future, you'll be able to sort on these falues as sortfields (I need to dig into the way I've been handling sortfields to make sure this happens).
