How does converting from WBFS to ISO work on dual layered disks?

[Otakumegane]

Just wondering because I don't want to screw up my files.

Is there software that takes the split WBFS files and puts them as 1 iso? Or will I get 2 isos in the end?

A split .wbfs file doesn't necessarily mean it's a dual-layer disk game. File size max was capped to 4GB that's why a second part may have been created if necessary.
To convert your file just select the first part. Both parts will automatically be converted as a single one
