I couldn't find a gamebase for MSX, but the TOSEC archives seems to do the trick Each page below has a zipfile link to download, they're really the nicest archive of MSX stuff I could find.

Are there any objections or forum rule breaks about posting links to my GameBase here?.
the latest version from 2017.
it merges the two previous msx1 and msx2 gamebases from 2008,
and adds TurboR, PD magazine disks, homebrew dev, Korean carts...
with custom BIOS files to automate the CAS loading.
