Hi there not sure the best place to start with this one -
I'm looking for advice about which emulator/rom set to use to make a box to play all the light gun arcade games - up to and including as recent as possible - I have a couple of the Ultimarc guns coming
Also what spec PC do you recommend to run this properly?
Hey , welcome!
Obviously the faster the PC (ssd drive etc..) the better the game play and more modern you can go , although there seems to be nothing that requires "gamer" style PC, best thing is try it with what resources you have and move on from there.
Complete up-to-date PC based light gun pack, in short, no.
