Damn, that is lazy.....but I suppose getting from the start to world map is a bit of a mission.
I'm not sure, but the *only* way to get the transition to look perfect (damn slow), is like I said before, to set Framebuffer Effects to 2. If we can find a config to get it to work on 3, then it should be ok, 0 and 1, no chance, and on 2, only way to not have a slow-down is to sacrifice a lot of graphics.
I uploaded the savestate, on world map. About 1.5mb, NTSC version. Hope it's the right one
