I believe its the dos version but im unsure , i had to get it from other means... i used to have the original but was all given away years ago to oxfam.. When i run it in windows it just loads and exists straight away, if i load through dos prompt it says load VESA.COM which then gives an error. The only way for it to work for me is dosbox, but is abit laggy.
edit : my friend sent me this hmmm
