Or install 2.2.9 to somewhere else. I think InstallShield lets you
choose the destination folder.

#877E.

A rough calculation suggests that given a room number, the entry for
a room is at

#5020 + ((room number << 3) & #700) + ((room number & #1F)*2)

- disassemble from #8099 to check my calculations.

You increase or decrease the number of rooms on the "Game" page. Be
warned that if you decrease it so that the room you're editing doesn't
exist any more, JSWED will crash.

Oh, better than that. It regenerates the dictionary every time you
save, and seems to do a better job than whatever or whoever compressed
the original JSW2.

My personal view is that JSWED should export them as ramps, though I
see that at the moment it doesn't.
