MAME4droid is a version of iMAME4all (iPhone, iPad) for Android, all of them developed by David Valdeita (Seleuco), port of MAME 0.37b5 emulator by Nicola Salmoria and TEAM, and it is based on GP2X, WIZ MAME4ALL 2.5 by Franxis.
MAME4droid emulates arcade games supported by original MAME 0.37b5 plus some additional games from newer MAME versions.
This version emulates over 2000 different romsets. (see at the end of document for a list of games that could work).
Please, try to understand that that with that amount of games, some will run better than others and some might not even run with MAME4droid.
Please, don't email me asking for a specific game to run.
Owners of older devices should not expect good performance. Tips to help performance: use lower quality sound or switch it off, use 8 bit depth, underclock the CPU and Sound CPUs. Disable stick and buttons animations and disable smooth scaling also.
After installing, place your MAME-titled zipped roms in /sdcard/ROMs/MAME4all/roms folder.
MAME4droid uses only '0.37b5', 'GP2X WIZ 0.37b11 mame romset'. Use "clrmame.dat" file included in /sdcard/ROMs/MAME4all/ to convert romsets from other MAME versions to the ones used by this version, using ClrMAME Pro utility, available in this URL:
MAME4droid will never have "save states" since it is based on a MAME version that does not support it.
Good app, great value.
PS A quick addition to my previous post. 'Indiana Jones' runs just fine =) Sadly, even with the update I cannot get Turtles or 'Golden Axe' to play and as a Mac user cannot use the suggested method to change romsets for compatibility. Still, this emulator shows great potential!
Finally, a MAME app for Android that actually runs =)
At present I can only get a handful of my hundreds of roms to actually play... but the ones that do open up run with very little slowdown and, unlike Tiger, play full sound! Score!
The interface is very easy to use and I'm very happy with the progress this app is making. I'd love to see support for more of my favorite oldies such as 'Teenage Mutant Ninja Turtles' and 'Indiana Jones and the Temple of Doom', but perhaps this latest release addresses that (I have yet to try the March 2, 2012 update).
