VBA-Minimum
Here´s a funny binary of the cleaned & stripped core + GUI version.

http://spacy51.sp.funpic.de/VBA-M/VBAMin.7z
Not using assembler, so it might be slower. Also a lot of features removed. Just use it if you are curious. Has automatic save detection though. Save states not compatible anymore. Save states will not be comaptible with anything, only battery files. Screen capturing&recordning might not work anymore.

Next step will be rewriting the core to a clean C++ class in a static or dynamic library. After that is finished & working correctly, features will be readded in a clean manner. Don´t expect any binaries soon.
