That should be easy to do, specially considering that there will aready be raster effects if one of the players is drawn with background tiles like Bregalad suggested.SecretServiceDude wrote:While scrolling horizontally, it would look really cool if each scanline of the arena floor were scrolled just a little bit faster than the scanline above it.
I fully agree with him, as this would allow for really large fighters, something that would seem impossible on the NES. The down side is that we'd still be restricted to 3 colors per fighter, although it would be possible to use different palettes in different areas if we picked a rule that worked for both sprites and background (since players can be drawn with either one).
Sprites would also be used for effects like energy attacks and blood I believe, which would cause one of the players to flicker a bit, but I guess this isn't a big deal.
Fighting games have a lot of room for effects, because they are not very intensive logic-wise... after all, there are only a handful of active objects at a time and there is hardly a level map to collide with.
