This MAME4droid version is targeted to Dual-Core devices, because it is based on a high specs 2010 PC MAME build. Anyway don't expect arcade games of the 90 to work at full speed. With some games that are really bad optimized (like outrun or mk series) you will need at least a 1.5 ghz dual-core device (Cortex A15). This is related to MAME build used, since it is targeted to high specs PC's as i said before.
This version of MAME4droid was designed to be used with dual-core Android devices because it is based on the PC MAME version which requires higher specifications than the older versions.
Even with a high end device, do not expect "modern" arcade games from the 90s and beyond to necessarily work at full speed or compatibility. Some games like Outrun and the Mortal Kombat series are badly optimized and require at least a 1.5ghz dual core device.
With over 8000 games supported, some games will run better than others; some games may not run at all. It is impossible to support such a vast number of titles, so please do not email the developer asking for support for a specific game.
After installing, place your MAME-titled zipped roms in /sdcard/MAME4droid/roms folder.
MAME4droid Reloaded uses only '0.139u1' romset.
