Are you sure this was a Roland SC? This sounded pretty close to just plain old Adlib. Of course any sound font would sound better than fm synth. What would be helpful is to have the track played on an MT32 or a Sound Canvas to do a proper comparison.
That's the thing about these old games: they were totally made for how the MT32 and later the Sound Canvas sounded to the point where they would even chose an instrument that would otherwise not be fitting, but which sounded good on the original device.
Unfortunately for me, all of this happened way before I had money on my own or could convince my parents to shell out the considerable sum these devices would have cost, so I really don't know how these games were intended to sound.
Which makes me really sad as a huge video game music fan/nerd.

Sounds pretty good!
