Four revisions of Joust.src ? (Significant differences in every revision here.) #1

Why are there 4 revisions, JOUSTRV1.SRC to RV4 ? I thought only two ROMS were issued. I compared the code, and there are differences in assembly code instructions in multiple places in every file. I checked between RV1 and RV2, between RV2 and RV3, and between RV3 and RV4.

Looks like diff between 1 and 3 shows the additions of the pterodactyl fix.

A question I have is what code fills in the 3 bytes of ram at VSND? It's like the code that drives the PSG is missing.
