... and that is because there is no initialisation command for the Direction and Movement Flags in the 'Display the title screen and play the theme tune' routine. (Although it defaults to a value of zero when the game file is first loaded, in subsequent games it retains the value it was left with at the end of the previous game.)

Another thought - one of the other 'Willy' variables which is written into the cavern data in MM, but which isn't specified in the room data in JSW64, is the Airborne Status Indicator. So if Willy jumps into a Portal in one room (in JSW64), why doesn't his jump carry on into the next? I suspect that there is a command to initialise the Airborne value to zero that is hard-wired into the JSW64 portal code. If that is the case, then it wouldn't be possible to have Willy automatically jump upon entry to a room in JSW64 (something which can be done in MM, as discussed in message 7003).
