I got it to launch finally. Had to edit the lair.txt framefile I copied from my arcade cabinet. Was two lines; first line ..\vldp\lair second line 151 lair.m2v and changed it to just 151 lair.m2v since it exists in the lair.daphne folder with the game files. Dunno that the 151 needs to be there or not as I’ve not played with daphne since setting up my cabinet ages ago.
Didn’t get far tho, no controls. Working on that issue now and I’ll see how it runs. I’ll set it up on one of the pi 2’s afterwards, this is just curiosity as I want to gift it to a friend and I’m pushing it to it’s limits to see just what it can and cannot emulate.
