1. I don't follow the MAME community too closely in terms of upgrades. Lots of talk about this -- what's the difference between ROM sets for MAME .36, and those for current versions of MAME? Is there a way to "convert" existing ROM libraries, or how does one deal with this? Are all games affected?

2. I don't have a PPC device yet, but it's coming. What does one need to know about key mapping, and what are the key issues people seem to be talking a lot about? Does that happen sort of randomly, or are only certain devices affected?

Thanks...

ROM Sets have gone thru changes as the development of the emulator has evolved. There is no 'converter' for making current romsets into older type sets. you'll have to try and track down the older set. I am working on a newer release that will use the current set, but I got sidetracked with real life work a few months back and only just recently had time to do any work on MameCE3. I have a maintenace release schedule shortly and then I will focus back on the new version.

As for the mapping problem, this relates to the fact that every manufacturer seems to decide to change the internal Key mapping codes for each and every new model of their devices. The code for mameCE3 was using those internal mappings and had to be redesigned with each change. My last release used a function call that IDd the unit but it still required me to have the Codes. The next release should fix that problem as well. :)

hope that answers your questions.

Actually, all I have is the older sets. I'm mostly worried about MAMECE3 starting to use the newer ones, and I'm left with ROM sets I can't use. Considering it's difficult to find them anymore, that's kept me from upgrading my desktop MAME.

I was mostly wondering whether there was some "magic" upgrade event to MAME that changed the ROM set requirements in some significant way that rendered all the old sets inoperative.

I just received my Axim today, so I'm hoping I can use it with MAMECE3. I'll read over other posts and see what I can find on that one.

Nobody should have a problem getting *** CURRENT *** ROMS.
Check out: http://www.freemameroms.com/
I personally used Jamie (near the bottom of the list) and was very pleased.
Good Luck!
