PSP MAME4ALL v4.9r1 Hires changelog

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.

When talking about Multiple Arcade Machine Emulator, or MAME, we think retro coin-op video games. Well, we're all going to get more arcade goodness - minus the quarters, in TTYman's new PSP MAME4ALL release.

The PSP homebrew developer has released version 4.7r2 Hires, which features a couple of fixes from version 4.7 and then some. PSP MAME4ALL by TTYman is actually based on the GP2X releases by Franxis and supports PSP Hires (480x272), overclocking (133 to 333MHz), among other things. Here's the full list of fetaures from TTYman's blog post:

• Based on latest GP2X MAME4All releases v4.7;
• 480×272 full PSP Hires Support, now games with >320 orizz. and >240 vert. pixels are fully playable (Loderun, Galaga etc.);
• Overclock support, from 133 to 333 MHz;
• Fixed, Fixed Divided by 2, Software Scaled and Software Full Screen Stretched resolutions (all maximum 480×272);
• Frameskip as GP2X version (fixed 0-5, auto 1-5);
• Vsync on/off;
• Save configuration support, default and per game;
• Autocentering fix for all resolutions;
• Optimized compiled code as derived from GP2X version, but for PSP cpu (fastest graphics core!);
• Stripped & Packed executable, only 2.1MB;
• Original graphics theme from Gold edition;
• Music in menu (filename music.psp in data folder), in these supported formats: .MOD .S3M, .IT, .XM and .OGG;
• Added, as bonus, 1st classified OldSkool at Assembly 2007 Music Competition (Commodore 64 based), in .OGG format;
• Graphic theme 480×272 BMP skins support, both pspmenu480.bmp and pspsplash480.bmp in folder skins

Here are the changes from the last version, also from TTYman's post:

• 133 MHz in menu and while paused, for battery saving;
• VSync really works now;
• Corrected build configuration and Makefile, so sounds in various games are now back;
• Correct fixed, div2, sw scaled and sw stretched resolutions, with autocentering

A couple of known issues haven't been ironed out in time for this release but we can be sure that TTYman will stomp them out in the near future: version 4.7r2 slows down with general audio enabled, plus it doesn't have rotate support.
