Homebrew developer Cpasjuste dropped by QJ.NET PSP Development Forum and announced that he was able to make MAME4ALL compatible with the new PSP Slim & Lite. For the uninitiated, MAME stands for Multiple Arcade Machine Emulator. And the build ported by Cpasjuste is TTYman's latest take on the project.

Aside from the upgrade compatibility features, MAME GP2X v4.7 PSP for PSP Slim works exactly the same as MAME4ALL v4.7. With that said, here are some of the worth mentioning features of the said version:

* Based on latest GP2X MAME4All releases v4.7 & 4.6
* 480 Orizzontal Hires Support in menu and games, now games with >320 pixels are playable (Loderun etc.)
* Overclock support, from 166 to 333 MHz
* Frameskip as GP2X version (fixed 0-5, auto 1-5)
* Vsync on/off
* Save configuration support, default and per game
* Autocentering fix for most games when using FIXED/FIXED DIV2
* Optimized compiled code as derived from GP2X version, but for PSP cpu (fastest graphics core!)
* Stripped & Packed executable, only 2MB
* New Graphic theme from mame.net logo (TM) and mameworld.com Tim's covers (n.1 and n.2)
* Graphic theme 480x240 BMP skins support, both pspmenu480.bmp and pspsplash480.bmp in folder skins
