We do have tutorials for Fighter Maker (http://www.rpgrevolution.com/download/help-files_10.html
) but they're old Windows Help format and won't work on Vista I think.
Unfortunately, those files are extremely rare and I don't know how to find a different format. You might want to try 2D Fighter Maker 2nd Round, as this upgraded version still has an active community. You can find it at RPG Crisis
