well, my game has this version: "S.old.010".
From some aspects it is compatible with SCI0:
graphics: 16 color EGA.
sound: it can use Ravi GM driver for SCI0, which SCI01 games can't use.
interpreter: it can't use sci01 interpreters from qfg2 and christmas card 256, and it also can't use interpreters from early SCI1 games like sq4, jones, etc..
on the other hand,
it also can't use interpreters from late SCI0 games like conquest of camelot.
so I guess this game is a weird hybrid, don't you think?
