Deluxe Galaga MOD replay routine

Does anyone knows what is the MOD replay routine used in Deluxe Galaga ?

It's clearly descended from ProRunner2, but supports setting Tempo via cia interrupts. In addition to the standard 'M.K.' identifier it also recognizes 'EMW3' if that rings a bell for anyone.

Short for Edgar M. Wigdal, I assume.

Maybe it’s Prorunner v2.4 by EX4 but in the adf i found there is no replay source code just the packer.
Update : RTFM

Didn't find this version earlier when I searched, but maybe took those changes into consideration, though version in game is more system friendly and can use either CIA for timer interrupt (Looks like that part of the code might be from ProTracker_v2.3a_CIA.s or something close).


I've put decrunched ECS executable in the zone in case you want to look closer. Most relevant code starts at $356ba (in IRA parlance). Just above that is CIA Interrupt struct.

In the original ProRunner source code an alternate ID was used to signal that the module was already pre-processed (described in the docs). The latest version on Aminet of the game has the modules as separate files (though they're crunched, but not in any sort of hidden way), so I don't think that's the reason.

I had a convo with Edgar about his use of "EMW" in his earlier games. He liked the way each letter had 3 legs. I said "but its not your initials" and he changed it mostly in the future stuff.
