Have you been looking for a single app to unify all of your android emulators? Wish there was a way to show all of your different games with cover art and descriptions instead of just titles?Nostalgia is your answer. Nostalgia is a user interface compatible with many android emulators (check the list further down). You install the emulators and then use Nostalgia's configuration menu to set the emulator to use and the rom directory AND go out and fetch the best shot at the cover art and descriptions for the games. Once those steps are done you will have a fancy new menu for each of your emulated systems with cover art and all.

Nostalgia is still in development. Ideas are always welcome!
Come chat about Nostalgia in the unofficial ouya chat in IRC (#whouya on freenode)

As always, Nostalgia only costs $1 to unlock fully and permanently.

The ONLY limitation in demo mode is that you can only select one game system to launch an emulator. You can still use all the other features and fully populate all of the menus for any system you have so you can see what it will look like.
