For this one, I used more channels (instruments) than usual on FamiTracker. It means more work for me, but in the end it sounds way better, so I'll keep on doing this for my next covers. The drums are in better quality, that's because I used samples that were used in some NES games. By the way, which Muse song do you want to see 8-bitified ?
