So I was thinking about this a bit more today and was looking at the game list for Model 2.
From what I understand you can't interchange ROMs between Model 2/2A/2B/2C PCB sets, however there were a number of games that were released on more than 1 hardware version so there are ROM sets available for each supported hardware version.
Kicking out games with specialized cabinets (like racing games, gun games, an other weird games like top skate and rail chase) and leaving in games that could be played on a candy cab with an appropriate panel (like Virtual on and Dynamite baseball) we're left with this:
Dead or Alive (2A or 2B)
Dynamite Baseball (2B only)
Dynamite Baseball 97 (2B only)
Dynamite Cop/Dynamite Deka 2 (2A or 2B or 2C)
Fighting Vipers (2B only)
Last Bronx (2B only)
Pilot Kids (2A or 2B)
Sonic Championship/Sonic the Fighters (2B only)
Virtua Fighter 2 (2A only)
Virtua Fighter 2.1 (2A only)
Virtua Striker (2B only)
Virtual On (2B only)
Zero Gunner (2A or 2B)
the "Model 2" and "Model 2C" hardware are nothing but specialized games, and so all of the standard-cab-capable games all fall under "Model 2A" and "Model 2B". not only that but the only game here without a Model 2B ROM release is Virtua Fighter 2.
As I understand it, of those games that have ROMs for more than one hardware version, the asset ROMs are the same and it's only the program ROMs that are different. I wonder if a game like Dynamite Cop that has ROM versions for 2A, 2B, and 2C could be used as a template for converting Virtua Fighter 2's program ROMs to Model 2B hardware... While still a small game list it would get all of the "playable" games on one hardware platform.
For the sake of completeness these are the other Model 2 games:
Driving Control Games:
- Daytona USA (2)
- Indy 500 (2B)
- Manx TT Superbike (2A)
- Motor Raid (2A)
- Over Rev (2B or 2C)
- Sega Rally Championship (2A)
- Sega Touring Car Championship (2C)
- Super GT 24h (2B)
- Wave Runner (2C)
CRT Light Gun Games:
- House of the Dead (2C)
- Virtua Cop (2)
- Virtua Cop 2 (2A)
Mounted Gun/Analog Trigger Stick Games
(IMO These are the next most likely to be played in a standard Cab):
- Behind Enemy Lines (2C)
- Gunblade NY (2B)
- Rail Chase 2 (2B)
- Sky Target (2A)
"Other" Control Type games:
- Desert Tank (2)
- Royal Ascot II (2C)
- Sega Ski Super G (2C)
- Sega Water Ski (2C)
- Top Skater (2C)
