Recent builds of MAME and it's many derivatives.
AdvanceMAME is an unofficial MAME version with advanced video support for use with TVs, Arcade Monitors, Fixed Frequencies Monitors, and also for PC Monitors.
MESS (Multi Emulator Super System) was fully integrated with MAME (Multiple Arcade Machine Emulator) as of v0.162. This has increased MAME's ability to not only run 1000's of arcade games but 1000's of computer and console games as well.
MameUi is the GUI (Graphic User Interface) version of Mame. Simply put, if you are not familiar with command line programs such as the official version of MAME, you will find this version much easier to use.
A continuation of the original Mame Plus.
This project is focused on merging the Arcade64 + HBMame system, The main thing has started by updating the Roms Sets from version 0.245 - 0.260, then it continued with a total cleaning of the roms thus eliminating hundreds of useless roms or .chd and unnecessary and thus to be able to generate a collectible edition and in this way a single version will be published. So that we can leave the roms system much lighter for our hard drive
