This prototype appears to be very very close the final
version. The date on the EPROM is a bit odd however.
It says 6-14 but the code itself seems to date to around late
March or early April since Landon said he finished the game up in
spring of that year. This means that the date was most
likely when the EPROMs were burnt rather than the code date.
An interesting difference in this version is that the scrolling
message is not shown when played on a PAL system. This is
most likely due to the timing loop for the scrolling code not
working properly on PAL systems which was corrected in the final
code (sort of). The scrolling message is present when played
on an NTSC system though.
While this version has the easter egg in it, the code to
activate it has been disabled. This was yet another compile
time option that Landon put in the code and it defaulted to
off. Interestingly the final bytes of code in this version
are filled with the text 'PIRATES BEWARE' which only appears in
this prototype and the Best Electronics prototype due to the copy
protection still being enabled. As the final versions were
compiled from code, the copy protection was disabled so this
message does not appear.
