Omega has released a new modified ATI Catalyst 3.7 based driver suite for all Windows OS.

Changes:
* Based on the official Catalyst 3.7 ATI drivers. (9x/ME/2k/XP)
* Hope to have fixed all the "card not recognized" problems. (9x/ME/2k/XP)
* The 9500->9700 and 9700->9800 hacks are now two separate files, this will fix
some incompatibility problems in 9500 cards not liking the 9800 optimizations. (2k/XP)
* The 9x/ME drivers still don't have the hacked driver incorporated, sorry. (9x/ME)
