Zx-81 has been steadily updating his Atari emulators for the PSP lately, with PSP2600 and the Atari 800/130/5200 emulators getting recent facelifts, and now it is the turn of his Atari 7800 emulator. This emulator is based upon the ProSystem emulator for PC, which Zx says 'is the best emulator of the Atari 7800 game console running on Windows.' Many new features have been added in this release, so let's go straight to the changelog:

* New graphical functions with new smoother render modes. It uses the PSP GPU for rendering and although it does not run faster it is a lot smoother.
* Added a new fullscreen option (render mode max)
* Rom selector support now recongnises .rom and .bin as valid file extentions
* Save state dates are displayed in the emulator window (it's now easier to identify and to load the right save state slot)
* Multiple keyboard mapping feature added (Thanks to Pou-chan) :You can now toggle between three differents keyboard mapping using LTrigger and RTrigger keys
* Bug fix in Rom file requester

You can find the specifics on how to use this emulator in the readme, and for developers the source code for this emulator has also been included in the download. Prepare to have some vintage Atari fun!
