I cannot find a way to get another exe running like under pin.mame in the old EL versions.
Because all supported emus except mame and Daphne wich are not useable for that do not get a .el (under /arcade) and a .ini (under /emulator_ini) file created from EL. I can create such files i.e. for HBmame, but nothing will happen.
So, I will work with the old EL. There I run WinAUE, NullDC... whatever I want together with all the Mame games.
