No.19698 ICEknight Tester Jan 17, 2022, 22:17	Should some kind of globally accessible "multiplatform.xml" softlist exist to avoid duplicates like these? Asking because, otherwise, things could start getting really bloated once games like the X68030/Windows DVD version of Road Blaster start getting added (or even WAV files for certain quite long multiplatform cassettes, like AWARI).
No.19699 Tafoid Administrator Jan 18, 2022, 00:54	There are multiple examples of cross system and fully compatible media either on the same image or as a "flippy" (side A and B both handle different systems). As of yet, there is has been no decided way to handle this outside of completely sharing softlists between systems as clone lists. The biggest duplicate stuff I've seen for size has to be the fmtowns_cd <> pc98_cd crossovers consisting of dozens of shared entries (and many GBs) duplicated between both lists. Acknowledged for now so there is an entry related to such media.
