Yep. I recently launched PiMAME.org - Most of the info is on http://blog.sheasilverman.com, but this weekend I plan on updating the main site.

Right now includes AdvanceMAME, GNGeo (NeoGeo), and PCSX_ReARMed (Playstation).

The installer is available on github: http://github.com/ssilverm/pimame_installer

I'm planning on adding AdvanceMESS, SNES9x, and MAME4All this weekend.
