Definitely want to see the built-in LCD screen for the Sega CD. What model Sega CD are you using?
Did you end up doing any eeprom flashing/repro making at all? I was thinking about getting the supplies to at least do NES repros.
It's definitely not worth as much now as it's MSRP was back when it came out. I have a CDi-220, and I remember the commercials. Those things weren't cheap when they came out. A while ago I traded my dad a bunch of comics (he's a collector) for my current CDi and several games. Right now on Ebay you could get yourself a CDi-220 for about $99-199. Not too bad really for what I got it for. Zelda:WoG is about ~$70 in really good shape.
