I haven't played these in awhile and they were working fine off usbloader GX on the earlier versions of the cios I was running but now they get to the now loading screens and hang permanently. I'm on 4.0 and cios rev 17 currently. Usbloader is a seagate freeagent go. I have tried going back to 16 with the same problem. I don't know where I can get 15 anymore to test that out.
