I will check that as soon as I find some time.
If you use split merged sets, you have to triple the streetfighter chd and you have to put it in each subfolder.

So you got:

roms\sfzj.zip
roms\sfzjr1.zip
roms\sfzjr2.zip
roms\sfzj\sfzj.chd
roms\sfzjr1\sfzj.chd
roms\sfzjr2\sfzj.chd


*Edit* ok...for full merged sets and enabled dupe-check you'll see the "exists in various rompath" message. This is wrong and will be fixed in the next version. It's a little sideeffect of the sfa set which -as a parent- doesn't have a chd while the clones do....
