 Another Space Demon video for confirmation here:


Importantly, this Epson melody IC does NOT appear to be on an original Nintendo Space Firebird as it doesn't play...


...and it doesn't show up on the Sega/Gremlin schematics either (used in both videos above - seems the OP of the first one can't find the 7910):

If it's like the other 7910E chips, it may need to be decapped, per the notes in phoenix.cpp.
