I heard with a jailbroken NT mini, you can play more than just NES games and compatibility is high. The newest betas for N8 (don't recommend, the latest, RC7, though. RC4 is the most stable and the ability to increase the expansion volume above 100% in RC6 isn't too useful for many games) now have full MMC5 support, along with much better FDS sound, but still have some bugs to be worked out. RC7 of Everdrive N8 has crash issues with MMC3 games on AVS.
