MAME Roms updating

[Richardgregory]

I'm using a full set of 0.157 ROMS with MAME 0.171 and all the titles are loading and working fine.  Maybe I'm not understanding something entirely here but is there a need for me to use a utility like clrmamepro to bring it up to 0.171?

I see DAT files posted and don't understand why one would need to update the ROM set to match the version of MAME that is being used.

My experience is, if it works for you, do not touch anything. Unless you are dead set on having the most correct emulation, or you must have that new game, your best bet to arcade bliss is to use the set you have now. Newer version of Mame are notoriously known for sometimes drastic loss of emulation speed in favor of emulation correctness. Mind you, this is the goal of the Mame project.

So if your set works for you, stick with it. Most FE can support multiple versions for any particular game you might want to play anyway...
