I have read through this once and am pretty much going to pick one up eventually. But how are the TATE games on a horizontal screen? Does it just have the black bars on the sides?
Yes, and note that it uses nearest neighbour scaling, which is kinda nasty, but overall, it's well worth its asking price and a hell of a lot better than other similar boards on the market. Even if you only end up liking a single game on the board, which is hard to think, it pretty much already paid for itself.
Ultimately though, real hardware wins, but as i mentioned before, the pandora is super convenient, runs well for the most part, and is cheap. Finally, let's face it, who wants to see Windows boot up when they turn on their cabinet?
