There are several that don't convert with the tool. The latest version of the tool I see is 3.0 from 2005\2006. It's still an impressive tool though.
Big Banker converts but the disc reel in the middle is a mess. I remember the initial release alteremu saying about the card symbols on the reel being tiny. Big Wheel has an error as I previously said, in this thread.
Those that do convert then generally will work, particularly jpemu layouts.
Once converted, add the background and roms.
Then I found it's a matter of setting the stake/prize, the meters, lamping the reels, holding ctrl and dragging the off screen buttons onto the graphical buttons on the DX and adding a coin mech. Finally I've since found out adding transparency to some lamps, is required to stop the black borders and graphical glitches around them.
Strip by Pook converts ok, I just need to add a coin mech to it. That one needed lots of lamps set to transparent.
