So I'm trying to play Rock Band 3 from an USB hard drive, it's a 1TB Samsung NTSF drive and I have transferred the iso using Wii Backup Manager. I load it using ios249, it boots fine, I can access and play the entire game with it. The problem is that whenever I'm playing a song, every 5-7 seconds the hard drive will light up to load something, and at exactly that point the game will not accept any inputs (while the song is still going), causing me to drop all inputs and fail every note. This happens constantly, the game has to wait for the HD to load something and doesn't accept inputs for 1-2 seconds, every 5-7 seconds, making it very frustrating to play when your notes are dropping every few seconds. I made sure this was the issue by unplugging the HD mid-gameplay, and sure enough the song continued for a while but the game didn't accept any inputs at all, before it froze soon after. So in short, the game hangs and semi-freezes whenever the HD starts up to load the next section of the song. Can I fix this at all? Maybe a special ios? Fat32 partition? Running the game from a flash drive? I tried running a burned iso through Softchip but had no luck, green screen and freeze, and my flash drive is fried so I'll have to go out and get another one (but would rather not unless I know for sure it will fix the problem) Any ideas? Thanks.
