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 features 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.

Anyway, check out the emulator by downloading it below. Be sure to go over the readme files included in the zipped file for more information about PSP MAME4ALL. Enjoy!

If you're a fan of arcade games and willing to put in a little time compiling a program to run it, then MAME4ALL is right up your alley. Franxis has released the source code for versions 4.6 and 4.7. These optimized versions of MAME is based on the gpx2 port and offers better compatibility (more games supported) than previous versions.

If you're new to the whole emulation scene, MAME stands for Multiple Arcade Machine Emulator. Designed to emulate the hardware of arcade games, it was first publicly released on February 5, 1997 by Nicola Salmoria and the rest of the MAME team with an open-source license.

Installation isn't very complicated, but you will need GCC 4.0.2: DevKitGP2X rc2 to compile the code or a slightly modified version of GCC 4.1.0 (DevKitARM r18) linked with GCC 4.0.2 (DevKitGP2X rc2). Before doing anything go over the Read Me document included in the compressed file to avoid potentially damaging your PSPs.

Thanks to Francisco Vergara for the tip!

This latest version contains the following updates:

• Added - full screen only in 'HW Scale' Option (does not work for all the games)
• Added - analog control
• Added - further support for ROMS
• Bug Fix - The memory that impeded the regeneration and left sectors of the ROMS without cleaning
  
• other misc small bug fixes

UPDATE: The file for the 2.xx PSPs should be ok now.

This version contains improvements such as:

Current bugs in this version include:

• Sound is not 100% working in the majority of ROMs
• ROMs larger than 10mb (zipped) doesn't work
• Not all the games that previously worked in Chui's MAMEGP32x work in this version
  

Kech is also working on the possibility of loading the ROMs through Wi-Fi. He's also very much open for constructive suggestions, to reach him, just click on the thread below.
