This is what i did - I do not use setdmd
After I did this I deleted all the ROM entries and when you start a new game it just makes
a new ROM entrie with all the correct settings
1) Setup the DMD for one VP table manually the way you want it.
2) Open the registry and locate Computer\HK_LOCALUSER\Software\Freeware\Visual PinMame\default and delete that entry
2) In the registry, now locate Computer\HK_LOCALUSER\Software\Freeware\Visual PinMame\<rom filename> for the table you manually setup and rename it to Computer\HK_LOCALUSER\Software\Freeware\Visual PinMame\default
All new tables will automatically pick up the Default settings
