Networking/Linked machines
« on: May 26, 2019, 11:43:27 PM »
Title says it all. Haven't seen any threads regarding this discussion of using two emulator instances to link each other in games that support that. The most common way would be to...
  • Set up either two emulator directories.
  • Set up an ini file in each directory stating the rx port and tx port.
  • Set one both emulators to their respective network ids (master or slave) either via dipswitch or test mode.
  • Have fun :)
Now for the list of games in this emulator that have networking capabilities:
  • Super Street Fighter II - The Tournament Battle, CPS2
  • Riding Hero, Neo Geo
  • League Bowling, Neo Geo
  • Thrash Rally, Neo Geo
  • F-1 Grand Prix
  • F-1 Grand Prix Part II
  • Driver's Edge, IT32
  • Dirt Fox, Namco System 2 (the rest of the linkable games on this hardware are unplayable)
  • GP Rider, Sega X Board, only released as a twin cabinet using a shared ram sub-board to bridge the two pcbs, not a network link.
  • Super Monaco GP, Sega X Board
  • Royal Ascot, Sega X Board, incomplete dump.
  • Power Drift - Link Version, Sega Y Board, currently in MAME but not in FB
  • Cadash
  • Ground Effects
  • Gunbuster
  • Double Axel, Taito Z
  • Racing Beat, Taito Z
  • Chase Bombers
  • More to come soon
Most of these games communicate via shared ram controlled by either an additional cpu or custom chip. How these functions are mapped obviously depends on the hardware. Sega X and Y board's network pcb are similar in design. Namco System 2's method of linking, C139, is used in later hardware that may or may not be supported. I hope this thread will serve well to this community.

It would be kinda neat if someone wanted to figure out how to link one (or more) of those games, as far as I know, nobody has tried yet.
