im have a version of advance mame that can use roms >120 ish, the site mentioned by one of the previous posters
was where i got it, he did another couple of versions of advancemame , and also a vsyncmame version which works well and uses later rom sets,the mistake
he made was to not publish the source code for some reason which violates the open source thing,these would maybe have got more attention if he did,but im glad to have them anyway.
they work well for dos, and vsyncmame is very easy to use but not as config friendly,i tend to use it most tho because of ease of use(im lazy).
