This specific version (0.145) was released in . It is considered a "Legacy" set. It is often sought after because it is the last version fully compatible with older XBOX original ports, certain antique Android devices, and low-power PCs, while still containing a massive library of games.

Additionally, the MESS half of the set gives you the ability to boot Commodore 64 disk images, NES cartridges, and even Apple II floppies without a second emulator.

Modern MAME sets include hundreds of games marked as "preliminary" or "non-working." The 0.145 set has a relatively high ratio of green (working) games compared to its total count.

However, if you crave the latest Cave bullet hell shooters, Sega Model 3 racers, or accurately emulated analog sound circuits, you must move to MAME 0.200 or higher.
