Do ROMs get "old", and not work well with newer versions of MAME?
« on: August 16, 2009, 04:18:46 pm »
If I had a set of 0.74 ROMs, and when I used them with the latest MAME, why would they work slower, crash, some not even start up, etc?  I was under the impression that a ROM is a ROM is a ROM, and they would work with any version of MAME?

no, they are packed differently as mame evolves - there is a good tutorial on using clrmamepro if you google for it which will sort the roms out based on the dat file made by your current version of mame.

the mame release page http://mamedev.org/release.html has a what's new link, that gives you a pretty good idea about how things change all the time. Bug fixes, new decryption, etc.
