it should run an install process and then the jar file will act as a link to the game location
when you open up task manager as long as you are using windows the command line will look like this
“C:Program FilesJavajre-1.8binjavaw.exe” -jar “F:GamesEmulationRetroFECollectionsRomsCatacomb-Snatch-1.1.0-BETA.jar”
the first quoted area is the location of java, the second quoted location is where the actual file is located, i have this in my roms folders to have it launch with retroFE
if you have coinops installed simply place the Catacombs Snatch jar file in the PC games rom folder edit the PC games settings.conf file in the Root of PC games folder
list.extensions = bat,cmd,jar
as long as the jar extension is there the game should be able to launch without trouble from coinops
the one nice thing about this game, you do not have to build bat files for the game to launch as long as the game is in the roms folder under PC games i believe you will have this running with little to no trouble.
