The solution: sys-default-paths.

Add a folder on your disk for each system you like to have separated. Now assign these paths as sys-default-paths. Click on 'Systems' (e.g. in the rebuilder). Assign the newly created paths there (doubleclick the right column entries). Autodetect won't help you since it would assign all to systems to your current rompath.

Currently there's no automatic move to sys-default-paths (although that's a fine idea for the future), so you have to rebuild your sets to these new folders.
Enable the "use sysdefpaths" option in the rebuilder and rebuild your sets (source points to your old collection). Be sure you keep 'recompress' disabled (otherwise it'll take much too long).

After that you got your sets separated in the sysdefpaths.


For future Scanning you have to change some things:

Remove your old rompathsettings and add the newly created folders as rompaths. (Here you can see that sysdefault paths don't necessarily be rompaths....for scanning they have to!)

When using sysdefaultpaths you should enable at least one scanner advanced option: "use sys-default-paths for fix missing". This is needed if you add new sets via fix-missing. There's also an option there which lists sets which aren't in the correct sys-default-path (detect sets in wrong sysdefault path), usually people keep that enabled when they work with sysdefaultpaths.


Sounds complicated? Nah...it's easy 8)



So again:

- add new folders, set them up as sysdefpaths and rompaths
- rebuilder: keep 'use sysdefpaths' enabled
- scanner advanced: enabled 'use sysdefpaths for fix missing'

That's it 8)



...and I guess I will add an automatic "move to sysdefpaths" option somewhere and maybe some automatic generation of them. Time will tell.
