If you're an avid retro gamer like myself, you probably snagged the $1.99 preview build of n64iOS on Cydia, hoping to enjoy classic titles. Unfortunately, in it's current state, the N64 emulator for iOS is more of a tech demo than a working emulator. Although games run at near-playable speeds on hardware as old as the iPhone 4, the many graphical glitches combined with the jumbled control scheme make most games unplayable.
Shortly after the emulator was last updated in May, ZodTTD posted on Twitter that there would be an update which would revamp the entire UI, including the ROM manager and the wonky controls. Since then, there has been no new release of n64iOS. That may be changing soon: According to a recent conversation with Will Strafach, ZodTTD is once again working on n64iOS.
