Do you not have these files in your coin ops folder at all? Vm.txt defines virtual memory for each game that requires it. D: drive would be your dvd rom drive so i imagine this version of coin ops that you have needs to be run from a dvd rather than a hdd install
well seems you are very skilled with coin ops :-) ..do you know how to list the games in the way that only the very old arcade games are displayed ? and maybe a list of my favorites .... is that possible at coins ? ;-)
I wouldn't say i'm very skilled with regards to this emulator, I don't use it myself. Sorry I don't know if thats possible but you could ask on their forums here:
thanks a lot
