it works in WB.. both on my real miggy, under amigakit, 3.1 etc.
i've tried all whdload versions i could find (chip and no chip). doesn't work for all the other AGA pinball games (illusions etc) i have either.
i shall work through the list in a moment.
EDIT - it could be that they bring up a DOS window to select the level you want under normal circumstances
