Zx-81 from our forums has released a new version of his 800/130/5200 Atari emulator for the PSP, bringing PSPAtari up to version 1.0.4. This update is pretty much a graphical update, involving the release of a new logo and background as well as a bug fix. Here's the changelog:

* Added icons and background
* Modify the UI to be able to use custom background images (transparency)
* Sleep mode is now working (but only when you're in the emulator window)

Zx-81 would like to thank Shadow for this release, who is behind the amazing new background image and icons. Well done to him! Fans of PSPAtari will be glad to know that this release has sleep support, but as Zx said, be sure to keep within the emulator window when you try to sleep your PSP, otherwise you may find your PSP crashed when you try to resume it from sleep mode. Enjoy!

A tip for those who want to use 5200 Roms from Zx:

You have to load them using the original atari800 emulator menu (the yellow "Atari800 menu" option in the emulator window :)).
Then select "Cartridge management" then "Insert cartridge" and specify your disk image file, then choose the cartridge type 5200, and go back to the emulator using LTrigger.

Both firmware 1.5 and 2.0-2.6 combatible EBOOTs are included in the archive as well as the sources.
