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