Howdy,
I haven't got them yet so I haven't been able to see how stuff scales in it. It will be primarily for a mame and console emulator cab so all scaling ought to be done by the rig. Most of the stuff I like is from mid to late 80s up to late 90s. Most of those resolutions are divisible by 480 (I think, correct me if I'm an idiot) pretty easily. Because it's so big though, displaying in native resolutions of 320 and such would still look fine. I hope to make this cab the sort of be all of SD and lower resolutions. I'd like to get emulators for everything up to the Wii (when it's no longer supported) backwards. All of this seems possible as well, except for the XBOX, whose emulator is still in it's earliest stages.
Note that I have all these systems, and have no interest in full romsets, just for the games I like and probably already own. I do not own any boards though, but would like to have a full romset of arcade games (at least for the controls I install). If people are interested, I can post back with my impressions on the monitor when I have it in a few weeks.
Cheers,
Alex
