[quote]In a strictly 2D-viewed fighting game, it is critical and essential that both players have the same horizontal screen width.
No it isn't, it's only essential that both players have a fixed horizontal width that neither player can escape. The viewport itself can be as wide as you want.
They could allow hor+ by simply restricting players to a 4:3 square in the middle of the wider image. This would also fix triplehead quite nicely, though all you would see on the side screens is more background scenery, since the characters can't leave the 4:3 box in the middle.
My post was clearly talking only about situations where both players had single-display setups. For example, a 16:9 vs. a 4:3. You suspiciously avoided my next post where I mentioned the separate issue of triple head being messed up.
I had assumed by default that all comments in this thread were discussing the "playable width" and I apologize for not being clear in my comments.
I suppose I phrased it unclearly. I meant the horizontal width of the "playable area" as it appears on a
single screen. I didn't mean literally in all situations, that the resolution itself only gets allowed so far and then bam it cuts off to black. Come on.
