Tested without issues on my +2 with a Divtiesus Maple Edition divMMC as you'd already tested with a divMMC Future.. Have you thought about doing a native esxDOS version which loads the files directly off the card rather than having to access the .tap file sequentially? I've hacked together a version from the .tap file and I can send you my changes to do this if you're interested - it makes the loading faster and you can take out all those 'stop the tape' messages. :)
