There are, but you have to downgrade your VASL version to 5.9.2, your VASSAL version to 3.1.17 or 3.1.15 and your DASL boards to v4 boards.
By the by, it is the only workaround also for using the BF-1 DASL board in play, or the DASL overlays in play.
Something that REALLY needs to get fixed in the next release of VASL.
