Cross-Ref over emulators and romdirs?

[Lolonois]

I know [1] and the accompanied script admin/stats.sh but is there already a script which does create a cross-reference between which folder below ~/RetroPie/roms/ is utilized by which emulator?

If not it is not a big deal to create such x-ref, I just want to save some cycles / do not want to reinvent the wheel.

I need the x-ref for another topic I am working on.

TIA

No, there's no cross-reference.

EDIT: to expand a bit.
The association is done in each scriptmodule, by using addSystem during the configure phase (we're excluding ports which have a single folder). So you can search each scriptmodule for addSystem and - with some text manipulation - get a list of links (emulator -> systems). However, the issue is that some emulators supporting more than 1 system have parametrized this call so instead of of

addSystem "snes"

you'll see

for system in "arcade dreamcast x1"; do
  addSystem "$system"
done

which doesn't work anymore with the approach above.

Et voilà ! [1] Code could be more elegant, but it does the trick. Comments/corrections welcomed.

Thanks for your extra hints, @mitu .

Nice. Now make it a one-liner :).

Maybe this way around: As the information is dug up now. Why not adding an extra rp_module_systems to the scriptmodules properties which holds the folders/systems? That way the code for creating the xref could be reduced drastically.

That may not be a bad idea.
