Eastridge Technology Engine
Eastridge Technology Engine is a sound driver for the SPC700 programmed by Nick Eastridge. The sound driver relies on the SNES sending commands for each note the sound driver keys on, which means under normal circumstances, all of the music data is stored and processed from the SNES side, and thus is undumpable in SPC format.
Every single game has a unique build of this sound driver, with one of the games having two depending on the version used.
The raw build sorting notes can be found here.
These are the games where the sound engine was used:

Communication with the SNES
TODO (there are almost certainly going to be per-build differences on the operation of most of these)
Music Format
TODO (if not already recorded up there, probably will be mixed with the command lists... these are done on the SNES side, not the SPC700 side)
