maddog and a few others you just run the md.exe ( for maddog ) , no emu or anything , just need to hit F once the game starts in order to get it full screen , by default it runs with light gun or mouse/tracball .
as far as a FE is concerned each one is it's own emu ( or you can place all those types of games in their own sub dir and run 1 bat file that launches each one depending on the command line )
i could create a quick zip file with the sub dirs ( not the acctual games , just the dir structure ) and all the bat files including a dat file for almost all the digital leisure games ( excluding daphne ) just pm me if you need em
