I'm mostly a lurker but I have been keeping up with the most of the forum for the past few months, and I have done some searching around on this issue and haven't been able to turn anything useful up. Anyways, I've got some PS2 Logitech/Konami microphones that I'm trying to get working in RB2 and Karaoke Revolution, but keep getting the "you must have a microphone connected" message, even when I've got an extra Wii remote connected as the "placeholder" for the mic. I'm on 3.2U, trying to use both the Backup Launcher or Mrkinator's Rock Band Launcher both result in the above error. I believe I've got RB Launcher Channel installed correctly but one thing I did notice when following Mrkinator's guide and using multi cios installer to install cIOS37 as IOS232 is that it said "Currently selected to install custom IOS37 with IOS37 as IOS 232" and not "Currently selected to install custom IOS37 with IOS37 rev7 dip as IOS 232" as it says in the guide. I couldn't find the listing for "rev7 dip" unless I just missed it, or maybe had bad IOS37 files. I downloaded them straight from the Ninty links. Not sure if this would make a difference, and whether IOS37 addresses the mics at all, or deals only with RB hardware. Any ideas? Hopefully I've got enough information to go by. Thanks!
