Nervegas and the NES.app team have once again rolled out a new version of their Nintendo Entertainment System emulator for the Apple iPhone. We've covered version 0.99.02, so here are the changelogs for both versions 0.99.03 and 0.99.04:

0.99.03 [nervegas]

* Changed Speaker/Headet/Mute button to use colored indicators
* Tapping status bar now reloads lists + scrolls to top
* Added fourth game genie code slot; sped up game genie a bit

0.99.04 [nervegas]

* Screen flip to affect on emulation view, not browser
* Removed taskbar in landscape mode
* Enlarged full-screen mode A/B buttons for landscape view
* Enlarged full-screen mode directional pad for landscape view

As with all homebrew emulators, you'll have to go and look for ROMs yourself. Everything you need to know about NES.app is in the readme file, so be sure to check both the README and CHANGELOG files included in the download package before installing NES.app.
