Hello everyone. I've tried searching for the answer to this question, but have come up with nothing. I have a MAME machine with 5 USB joysticks in it -- 4 for players, 1 for function and player start buttons. All of these joysticks show up in Game Controllers in the Control Panel, and all are working 100%. With my previous frontend (MameWAH), everything was fine. After installing GameEx, 1 random joystick of the 5 will not respond in MAME or any other emulator, though it will work for menu selection in GameEx. At this point I chalked the problem up to being GameEx's fault, however, launching an emulator seperately results in the same problem, even if GameEx hasn't been run yet. The only thing that changed from a 100% working system was the installation of the v1.1 .NET Framework and GameEx. Will upgrading the .NET Framework to the newer 2.0 release fix the problem? Does GameEx change some system files upon installation? One more peculiar thing is when I setup controls for the 1st Player joystick in MAME. Normally, pressing the joystick in a direction results in a setting like "j3:sticky+", but now sometimes it results in "o k o k k o o k j3:sticky+". I know that you can press left-right to bypass the ROM legal screens in MAME (therefore typing "OK" if you don't have a keyboard plugged in). Again, I never had this error until I installed GameEx. Is this a bug with GameEx's configuration option of "Bypass Disclaimer/Warnings" (found in Advanced MAME Settings)? Sorry for the load of information. I will diagnose this further when I get home and go on an uninstalling and testing binge, but until then, any thoughts? Thanks!
