heres another longshot....
came across some nice coop maps called "paco's coops". they were all island based maps and seemed to run good except a sysdump issue after playing a few in a row.
culprit: no environment files in any of the maps. these are old and probably made with that original bhd to jo med from A Bullet.
what i feel is a longshot is the possibility of contacting this paco person to see if they still have the .mis files.
so, if anyone may have known a player named paco in jo that made a few maps some 16+ years ago, please ask them to get in touch with me.
