Importer improvements coming (Patreon)

Future update will have better rom matching for systems. 

Not sure if they updated it, or I just never checked, but went through OpenVGDB again and filled in a bunch of missing system info needed for ROM matches to work for systems like, 

PSP

Gamecube

Wonderswan Color (properly seperated from non-color)

Nintendo DS

Jaguar CD

MSX

MSX2

Odyssey2

Vectrex

Colecovision

3DO

Note, not all these systems have working cores yet, most don't yet (very actively WIP so don't ask cause it keeps changing).

You will be able to import and cores that are coming, beta, and regular will be marked.
