Cores are same like before. Only labels are changed. Previously there was checkbox, now there is spinner menu. It is because in developer version I use additional cores which are not in official release, but they can be there in the future. I needed to handle more then 2 cores.
V74 core is the same like unchecked checkbox “svn” in previous version. It is based on desktop dosbox 0.74 with additional functions for win95 compatibility
V4180 is the same like checked “svn” checkbox. It is based on svn 4180, it includes save states support.
