Each update to the emulator still means updates to the ROMs and other media associated with each game and system that MAME supports. Today, the MAME release cycle is still to produce a new stable version each month.

MAME users generally had to choose to either keep their ROM, CHDs, and audio samples up to date with the latest version of MAME, or to put together a system that was frozen to whatever version of the ROM set and emulator software was current at the time.
