Summary	07015: vr, vformula: Undetected communication board.
Description	Virtua Racing and Forumla doesn't seem to recognize their communication boards. Setting the communication to 'master' or 'slave' will load the cancelled screen instead of the network check screen even with a proper config. Happened since 0.196. Comm board emulation for these two games worked fine before. System 32 and Model 2 games are unaffected. Wing War, running on the same hardware, reads its comm board fine.
Steps To Reproduce	1. Run vr or vformula 2. Change linked setting to 'master or slave'. 3. Exit test mode.
Additional Information	Used the following setup for both cfgs: CFG #1: mame64.exe vr -w -cfg_directory cfg -nvram_directory nvram -comm_localport 15111 -comm_remoteport 15112 -comm_localhost 0.0.0.0 -comm_remotehost 127.0.0.1 CFG #2: mame64.exe vr -w -cfg_directory cfg2 -nvram_directory nvram2 -comm_localport 15112 -comm_remoteport 15111 -comm_localhost 0.0.0.0 -comm_remotehost 127.0.0.1 My guess is something happened so that the communications board ended up being undetected so both games think they don't have a comm board installed.

The reason was because the upright and 16:9 screen versions of vr didn't have comm boards installed unless operators wanted to pay extra to install the comm boards. From what I heard, the twin version was more favorable. vformula on the other hand has a comm board installed by default because they were only sold as linked units. Hope Sailorsat has something to comment about this.

From 0.196 to 0.197, there were a lot of model1 changes. My best guess of which commit regressed the comm board issue would be this: https://git.redump.net/mame/commit/?id=1d338061af66eed2cbf3e19655bb840f4e801c9c (Exactly finding out what went wrong isn't going to be an easy task for me for this seems to be a nice rewrite).

My initial commit didn't quite work out well (silly me). I myself can't change the status to "Resolved" in any way.
