me, i'm the dummy. currently updating mame from 144 to 146 and i've read in passing that with 146, chd's will use version 5.
well that sounds great on paper but what's an idiot like me to do? i have read that chdman, included in mame, will convert files to the new version 5. i don't want to mess these large files up, anyone care to offer some advice, a walk thru perhaps?
i ran an audit with clrmamepro (mame 146) and came back with 8 missing sets in my final report but the output window while it was running was filled with red x's, i'm guessing those were all chd errors but hell if i know

any help is appreciated...
