Hi Roman,
situation is as following:
1- datfile is straight from 0106u1 exe
2- rompath are: c:\mame\roms -> roms in zipformat splitted
c:\mame\chds -> chds, each one in it's own subdir
3- I make a scan with "set" and "roms" activated and I get an -susume.chd unneeded- error
4- I make a scan with "set" and "chd" activated and I get no errors.

Shouldn't it be the other way round?

TIA

ciao
