Absolutely!. I'm always trying to find the best upgrades I can use on any device, it's my nature, and I have the tools for it, but yes! I'm still happy to have one of the earliest versions!
Thanks.

IIRC you need a 256kbytes rom so a 27C020 and variants will work fine

Thanks for this, and other pieces of information on this thread!

I just updated my SC55 MkI from 1.20 to 1.21 ROM (using a 27C020). I am not expecting to ever notice the fixes, but I thought why not go all the way and do the upgrade 😁

I've had issues with my SC-55 mk2 when trying to play Blood. The issue is, almost none of the songs play correctly (almost all instruments are wrong, notes won't play, etc.). I just discovered that my SC-55 mk2 ROM version is 1.00. Funny thing is, the setup music works just fine and other games work great. Setting the music to General MIDI or Sound Canvas doesn't change anything either.

for update the Roland SC55 MK1 is just need the PCM.ROM and what about the sample roms are they needed too?

Regards
