Mame 078 Plus Romset Guide

The short answer: No, but with nuance.

If you are running a high-end gaming PC, you should use modern MAME (0.260+) because the emulation accuracy for games like NBA Jam, Gauntlet Legends, and Star Wars Trilogy is vastly superior today.

However, if you are building a Raspberry Pi arcade, a low-power laptop for a car, or a handheld console (Anbernic/Retroid), the mame 078 plus romset remains the gold standard. It offers the best compatibility-to-performance ratio for 70% of all arcade games made between 1980 and 2000.

Even though MAME is now on version 0.272+ (as of 2026), the 0.78 set has legendary status for classic arcade emulation: mame 078 plus romset

While standard MAME 0.78 was good, an unofficial derivative known as MAME 0.78 Plus (or MAME Plus! 0.78) became legendary.

The standard MAME build is a command-line application. "Plus" builds were unofficial modifications created by various developers (most notably the Plus! team) that added a graphical user interface (GUI) directly into the emulator. More importantly, they often optimized drivers and, crucially, improved support for specific arcade hardware, most notably the CPS-2 (Capcom Play System 2).

Because Capcom CPS-2 games (think Street Fighter Alpha 3, Marvel vs. Capcom, Darkstalkers) were encrypted, running them efficiently required specific decryption routines. MAME 0.78 Plus handled these exceptionally well. It allowed low-power devices to run these graphically intense 2D fighters at full speed without the stuttering input lag found in later, more "accurate" MAME cores.

Why are people still downloading a ROMset from 2004? Simple: Convenience and Size.

In the early 2000s, hard drive space was expensive. A full MAME set today (version 0.270 as of this writing) is over 70+ GB compressed. The MAME 0.78 Plus set? It is roughly 6 to 7 GB.

More importantly, 0.78 represents the “CPS2 / Neo Geo Goldilocks Zone.” Almost every major arcade hit from the late 80s to the late 90s runs perfectly on this set: While standard MAME 0

Yes. Two common “flavors” exist:

“MAME 0.78 Plus” also sometimes implies “MAMEUI 0.78” – the exact UI version.
