MAME 0.84 is often sought for low-spec devices (like early Raspberry Pi models or older handhelds) because it requires significantly less processing power than modern versions. However, because it is over 20 years old, many ROMs in this set have since been replaced by "better" dumps in newer MAME versions. MAME 0.84 - MAMEDEV Wiki
: A romset is a collection of arcade game files. For 0.84, these are often organized as "Merged" (parent and clone games in one zip) or "Non-Merged" (each game is completely standalone). mame 084 romset verified

For the purist who wants a slice of arcade history without the overhead of modern emulation, the is a treasure trove. It captures a moment in time when emulation technology had matured enough to be accurate, but before the code became too heavy for budget hardware. It captures a moment in time when emulation
Modern MAME is a beast. It requires high-end CPUs to accurately emulate the cycle timings of older processors. MAME 0.84, however, is lightweight. It can run a vast library of arcade games on modest hardware—perfect for building a Raspberry Pi arcade cabinet or reviving an old laptop. The 0.84 version is often cited as one of the most stable and fast releases for lower-end emulation boxes.
MAME is notorious for constantly renaming and restructuring ROMs. A game that works on version 0.150 might not work on 0.180 because a new chip dump was discovered or a parent/clone relationship was changed. MAME 0.84 represents a very stable era for ROM management. Once you have a verified 0.84 set, you rarely need to update it if your goal is just to play the classics.
