kinkladze10 - the trick is to map your left/right rotate keys the shoulder buttons - in the case of Bloodwych, (one of the greatest games ever btw) these are del/help, though a lot of other dungeon-crawler games use the numpad for movement, and so probably use "7" and "9" on that to rotate - i know EOTB does.
FOL is right, my youtube videos do show this being done to great effect
ill try and get a decent Bloodwych state up soon, which will include both game & data disk, and a nice tidy control system for menu naviagtion (L+dpad for F-keys etc) - although i must admit, i simply used an ADF of the cracked copy when i played through originally, (using savestates along the way) howver, this did make transferring my game to the data disk somewhat cumbersome, as the data disk has to use an especially formatted custom ADF for the save-game transfer, which often crashes winuae when you try to get it ready, and there is no proper crack of the data disk either (i used an ADF which contained the game save-stated on my original a500 with the action-replay cartridge)
at absolute minimum, i'll upload the 3 adfs i used for this for you (game, datadisk & savedisk) - although my integrated savestate would still be the better option!
EDIT - SaveState for Bloodwych now in Downloads Section
