WB updated the controller plugin to support the new machine Id and S12 controller configuration.
he don't have the time to test this version, but it appears that combos won't work with player 2 for S12 games, he'll try to fix it ... if he's got the time ;p
There's still a minor issue with dafreaks zincgui as well, something goes wrong with the creation of the dats for tekken(1&2), soul edge & dunk mania game. The parent information doesn't get parsed (just check the dats of those games the parent= info is blank while zinc --list-games / --list-sets, shows parent info, probably a parsing bug in the creation of the dats. So just open those dats & add the parent info. afterwars press rescan roms and u'll see it doesn't show bad or missing roms anymore. simple fix for the time being :)
