I have a set of 600 merged roms that I want to un-merge and include the necessary bios sets for each game. Can clrmame do this, and if so how?

Side note: I've tried using datutil.exe to build a dat using a list of games in txt file but it keeps hanging after 30 or so games.

You can use the new rebuilder to create standalone sets.

Thank you. So how do I create the xml for it? My set is 600 games. The only xml I have is the full mame 0.266.xml.

well, you need a current MAME one...e.g. via mame.exe -listxml >yourfile.xml. This is loaded in the rebuilder, input points to your current collection (+ recurse switch enabled), output to a new folder, mode should be set to standalone...and go....

Of course the rebuilder can't magically create files from nothing...you need all dependencies somewhere in your input....but if you have, you get standalone sets in your output.....

Ohh, so it automatically takes the limited custom set I have of 600 merged machines and rebuilds them using the full mame xml? I did a couple tests with 1 or 2 machines and it worked.

I don't know why I thought I needed to provide your Rebuilder utility with a custom xml with my specific 600 machines.

Very cool, thank you :)
