SFG-01 firmware does not automatically boot. Both require _MUSIC to start.

Oh you're right of course, I forgot I have a separate Yamaha cartridge that automatically boots the one with SFG-01 into a musical keyboard mode!

BTW an SFG-05 is being auctioned off here: https://buyee.jp/item/yahoo/auction/r497291221

Not my listing, and even with a couple days remaining the price is already fairly high, but it at least appears to be the real thing

Sander may still have some of those RBSC's SFG clones for sale. They are normal cartridges, so will be suitable for any machine.

I think it is Omega who is selling those, but they don’t come with the MIDI ports which the original poster would need for his usecase.

In the end I opted to perform the EPROM upgrade. Initially I had some trouble getting the original chip off the PCB with the soldering iron, but a hot air gun made quick work of it. Thank you all for your valuable input!
