I don't know anything about the mapper, I can't get it to work because of some weird issue I have. It says something like was expecting US version of Fallout 2 (or whatever it said, I forgot now) and couldn't get it to load. This was confusing because I live in the US and I don't have an imported copy of Fallout 2, as far as I know. I suppose it might work, if anything else does that's added with the mapper, but not sure.
Yeah, that Charisma thing is a pain in the arse.
