Overclocking, eh? I'll have to give this one a try. I'd love to see a smooth running Steel Talons.
Yeah, I have a Game Gear as well, and it's definitely less spec-tacular than the Lynx. As is the fashion, the better products generally go the wayside for whatever reasons. Like my NeoGeo Pocket -- the only bad part about this unit is the reflective TFT.
The best portable I own is the Nomad (out of the NeoGeo Pocket, Sega Game Gear, Atari Lynx, and original Gameboy.) Full Sega carts in a hand-held. It can also output SVHS, composite, and stereo sound. With an RF modulator and another controller, it can even be used as a quasi-full Sega Genesis. I can't find my SVHS cable, though :-(
One thing I think is really neat about the Lynx was the planned networking capability with the Jaguar. It was intended to work much like the Game Cube and the GBA (I think, maybe the DS?) work. But Atari kept slipping release dates and developers dropped like flies. Ah, well. I had a chance to pick up a Jaguar, CD-ROM, and a few titles from a surplus dealer for $25 total. Kinda wish I had.
