It originally started out as a release for the dutch folk because button numbers 0-15 were taken by the dil switches and thus machines with low button numbers did not work properly.
American dream and a couple of others were machines to suffer this ailment, this has now been fixed.
Also, the lamp export has been updated and the reel editor now works alot better for me.
This is a beta release and has not been comprehensively tested.
