Developer TTYman's letting the word out that he's releasing a new build of his Multiple Arcade Machine Emulator (MAME) homebrew, dubbed PSP MAME4ALL v4.9r1 Hires. At the forefront of this new build is an EBOOT built specifically for the PSP Slim - it should be available (and clearly marked) in the file bundle alongside the standard (PSP Fat) version. Moving, here are the rest of the noted changes since MAME4ALL v4.7r3 Hires:

* Crash when sampled used.
* Unified builds, thanks to new Z80 core, Mame 0.53 based, compatible with system16, neogeo and classic roms.
* Implemented PSP-2000 (slim) specific support, so double memory available to load roms, thanks to keiich-san code.

Installation and full changelog details should be available in the file's readme. Guys interested in posting their feedback regarding PSP MAME4ALL will also want to visit TTYman's release site. Enjoy the download.
