MAME4droid, developed by David Valdeita (Seleuco), is a port of the MAME 0.37b5 emulator originally created by Nicola Salmoria and his team. This Android version is derived from iMAME4all, which was initially designed for jailbroken iPhones and iPads, and is based on the GP2X, WIZ MAME4ALL 2.5 by Franxis.

MAME4droid is capable of emulating over 2000 arcade games that are compatible with MAME 0.37b5, along with additional games from more recent MAME versions. However, due to the vast number of games supported, performance can vary significantly. Some games may run smoothly, while others may not be compatible or may run poorly on MAME4droid. Users should be aware that specific game performance cannot be guaranteed.

For optimal performance, especially on older devices, users can adjust settings such as lowering sound quality or turning it off, using 8-bit depth, underclocking the CPU and Sound CPUs, and disabling animations for sticks and buttons as well as smooth scaling.

To use MAME4droid, users need to place their MAME-compatible zipped ROMs in the /sdcard/ROMs/MAME4all/roms folder after installation. MAME4droid is specifically designed to work with MAME 0.37b5 and GP2X, WIZ 0.37b11 MAME romsets. For converting ROMs from other MAME versions, users can utilize the "clrmame.dat" file found in the /sdcard/ROMs/MAME4all/ directory with the ClrMAME Pro utility, available at http://mamedev.emulab.it/clrmamepro/.

It's important to note that MAME4droid does not support save states, as it is based on a MAME version that lacks this feature. For the latest updates, source code, and additional information, users can visit the official webpage at http://code.google.com/p/imame4all/.
