[MAME import advice]

Does the CHD have everything? If I import the CHD set do I even need to mess with the other two? Or do I still need to add one of the split/merged Roms in addition to the CHDs?

[MAME import advice]

Hello,

 

I have the following- MAME .228 CHD's  (approx 2.3 TB)     Mame .228 BIOS ,  and then Mame .228 Split and Mame .228 Merged.

 

I have had supposed full sets of Mame before, but never had any luck with CHD's being missing. 

I know I wouldn't use both the merged and the split.   Which one is better for Launchbox import?  And then my main question is :  Do combine the CHD, bios, and then whichever split/merged I  end up choosing all in one folder before Importing or is there something else I need to do so they all work?

 

Thank you in advance for any help!
