So, I've tried running Knights of Valour, Knights of Valour Plus, and Knights of Valour: Seven Spirits on MAME 0.146 with no success (Says the game lacks one or more ROM/CHD files).
Does anyone have any links to working copies of these games? Am I missing a certain BIOS to run these games? Or am I lacking certain files such as the Parent roms or certain other things to get them to work?
Would really like to know, as my understanding of getting games to work using Parent Roms is kind of lacking.
