Exactly, my bruthah - looking at the overlay before you play is quite helpful! I have a Vectrex in the closet and was looking at it the other day - at least it only has 4 buttons and a joystick to figure out, unlike the beloved Intellivision. By the way, if you haven't tried that ParaJVE emulator for the Vectrex, you should - shows a great image of the actual unit and overlays while you're playing. Not ported for emulation station, I guess...but it's a terrific emu.
Now if I can ask one last question, my Ultimate INTV will be perfect! I find myself carrying the unit from one TV to another, some of which are 720p, and others which are 1080p. I've changed the es_systems.cfg file to 1280x720, so it works fine on the 720p TV's but of course doesn't fill the screen on the 1080 TV's. Is there any way to have this thing sense what kind of TV it's hooked up to and change the resolution automatically to fill either screen size? Or am I dreamin? The Emulation Station splashscreen seems to do that...at least, I think it does.
