PSP Homebrew developer TTYman is back to keep the oldschool emulation action on the PSP alive! This time, he comes with good things, as well as the latest version for the epic piece of software that lets us play MAME games on the go, PSP MAME4ALL v4.7r3.

Lots of bug fixes and overall improvements on this one, and most of them have to do with the cute chirping sounds those good retro games make as you're having your way with them. Let's check the changelog and see what's new from the previous version:

Fixed from v4.7r2:

* Sounds now are near arcade perfect, with minor gliches in some sound chips emulations;
* Gold (CPS1, System16 and Neogeo) specific emulations are now stand-alone, as require different z80 cpu implementation
* Improved performance with sounds, oldies with 0 frame skip and vsync on, others with auto-1 and auto-2

New features:

* 22KHz with 16 voices predefined sounds
* 33KHz and 44KHz frequencies with 4, 8 and 16 voices combinations added
* Preliminary analog support

Of course, there's still the odd issue or two that TTYman hasn't gotten to yet, but he's working on them. In the meantime, why not pop on over to the homebrew's official website and give props where it's due? As we all know, being appreciated for one's hard work is always a good thing. Oh, and be sure to read the readme files included in the archive before doing anything, mmkay? Mmkay.
