iPhoneNES v0.24 is out. This release seems to be focused on bug fixes. It includes speed improvements, better orientation flipping, and improved game support (PunchOut! and Metriod now work).
In addition, iPhoneNES has a new homepage and a new name. According to the new homepage, iPhoneNES is now called NES.app:
NES.app is based on the same code as iPhoneNES, but because they couldn’t keep up with all our changes, we thought it best to maintain our own site and svn repository.
