Thanks for you fast response.
I will try to explain better. Having the right roms working on Demul, bios is on the roms dir and Demul pointing to the right dirs. I have also the .exe to open Hikaru and Gaelco in FullScreen and make a script with ESC key to exit both emulators (needed in these platforms)
When I launch game opens DEmul so I have to open manually the rom and Works.
SOLVED: Apologies my fault, forgot parameters -run=hikaru -rom= . Thanks anyway!
