40 minutes sounds right, but IIRC you can wire multiple batteries in parallel (or is it in series?) and double, triple, etc. your gameplay time. Hitch the unused batteries up to a solar panel and you've got "free" Atari! Touché about the screen but maybe an old portable CRT would do the trick.
And yeah, I have several Game Boys and play them a lot (especially lately), but there's something about the idea of Atari in the middle of nowhere...
Ha! I was thinking more like Québec and the Trans-Taiga Highway, but if I'm ever in your neck of the woods, you might just get a PM. I've always wanted to visit Yellowknife, which is only another 16+ hours away, right? BTW how's the screen latency on your portable?
Yellowknife is amazing...in July! Seriously, working there for a year was one of the highlights of my career. Peace River is about a ten hour drive away from YK.
The portable is AMAZING. I bought it for a song ($200? $300?) about four or five years ago, and just love it. I'm going to have to try Kaboom! on it one of these days, but basically keep Keystone Kapers parked in it.
I like Keystone Kapers but I already scored a million on it.
