These things sound amazing. I used to own an orginal gameboy, way back when. never owned a colour and only seen someone laying on and advance.
But if u gameboy fans out there are interested the new gamboy sp is brill,, its been well re-designed and now has a proper back-lit. its basically a GBA in a new case design(i.e a flip down screen) with a backlit screen.
slightly more of topic, played Zelda on the GG last weekend, Im not a big fan of Zelda series, but the game looks really good and is interesting. Its all cell-shaded.
