Well I figured it out finally I've got both versions up and running the sad part is it's a pain but not too difficult. First have Maximus arcade make the list of games for the first version of Mame then make a copy the Mame.lst file. after that go to preferences folder and delete the original Mame.lst file now pick an unused emulator. I used Raine for example and point it to Mame instead. Also don't forget to add the command line %file -skip_gameinfo -nowindow now rename the copy Mame.lst file to Raine.lst now import it as the Raine list in maximus once that is all done maximus thinks it's running Raine and you have your second version of Mame working. if you have any questions please ask as i'm not the best at explaining stuff.
