Hi Badmouth,
Great news....you put me on the right path.
All working now (see screen shot below).
Edited the MAME CMD Script to point to a new file M2a, copied relevant folders and modified there contents, then in Mala (Daytona and Indy 500), pointed them to the new script m2a
100% working, all thanks to you, as I would never have thought of doing it this way
Thanks again mate
