Chiming in there is an auto-map hack and there is a saving+pause-map hack.
No Idea if they can be combined, but I doubt it.
There is something I'd like to track down myself.
There is a wall-jump patch available that is, frankly, not very good.
In my searching, I came across an archive for the old acclm board and there was an improved version of the wall jump the works pretty much like the SNES version.
However, the link to the patch is on a dead site.
Anyone have the improved patch?
