Many years ago I was emailed a remake of Bubble Bobble made in DIV, by a user called Paul Darby. As far as I can remember he never posted on div-arena
and this was the only game he made.
The prg is a staggering 20,000 lines long(!)
I've made some minor changes to this (bug fixes) and used it to help me make modern DIV more faithful to dos DIV2.
