I'm running the gamma backup launcher and a USB loader. What CIOSs and IOSs should I have by now? I updated my system to 4.0 a while ago and everything seems to be working fine, but slower. I tried to downgrade but the SD card still shows in the menu, so I'm not sure that I did it right. Everything seems to take longer: For example: - when I press A on the initial safety screen - when I click on a channel - when I click 'start' on a channel - any part of loading a game until it actually starts These all seem to hang for a while, but I can't figure out why?
