Homebrew developer Zx-81 released yet another of his emulators, this time PSP7800 for the Sony PlayStation Portable. Not long after the previous update, Zx-81's port of Greg Stanton's Windows-based ProSystem Atari 7800 emulator to the handheld received more convenient features.

Now optimized for better audio and support for IR Keyboard, users can also enjoy PSP7800 version 1.1.0 with these changes:

* Display and save thumbnail images for each save state
* IR keyboard support (mainly for menu)
* Add option to display fps rate
* Option to prevent the blue led to be displayed when L or R are pressed
* New psp clock option (it can now run at 133 Mhz)
* New speed limiter function
* New sound engine (always crappy but faster)
* Import code from ProSystem version 1.2

Zx-81 provided two versions of PSP7800 for firmwares 1.50 and 3.xx. For installation instructions and other important details about what Atari 7800 roms are compatible with this homebrew emulator, don't forget to check the Readme file out as usual. Doing so is the best way to familiarize with the controls and maximize your old school gaming experience on the go, too.
