NES.app v1.4.0 now available for download - Image 1You've got to hand it to the boys at NES.app, they really work hard in giving everyone a fool-proof and up-to-date version of their NES emulator for the iPhone. With the advent of the new iPod series, we might be seeing this little application on it sooner or later.

Until then though, developers nervegas and jordan have cleaned up several flags in the application as well as compensated for some overclocking instances. They've also finally managed to add support for a second player controller. Here's the complete list of the changelog for the current build for NES.app v1.4.0:
