As mame 0.114 came out I have some issues with chds.
Using clrmamepro v0.99c 's scanner i receive messages like this one:

Dance Dance Revolution 4th Mix (G*A33 VER. AAA) [system:
System 573 BIOS - folder: ddr4m - size: 517kb]
missing but fixable (-> ddr4ms) chd: a33aaa02.chd [chd-md5: d843cba35726f3b0af357f712b8870a4] [chd-sha1: 40456e772c39c339828dd4726766ef2e0981d3a1]

I haven't any chd named a33aaa02.chd but mame32 seems to like the "old" a33aba02.chd filename. I think clrmame is messing something...

On the other hand, if I check the advanced option "allow chds in rompath root" and I move every chd in a common directory, I don't receive any error message but mame32 won't run the game anymore ('cause chds have to be located in specific directories)

What's the problem?

Thanks
