[Feature Request] Famicom clone second lightgun support

[StormedBubbles]

Hello,

The following two games support dual lightguns on Famicom clone systems:

• Fantasy of Gun (from "Super 4 in 1")
• Hit Marmot

The simultaneous two-player modes of the above two games appear to be unsupported in lr-fceumm currently. Only one gun will work, and player 2 remains inactive regardless of settings. Note that dual lightgun support in the emulator is currently possible with Zappers in ports 1 and 2 for

• Chiller
• Zap Ruder

so I am guessing that dual guns for the Famiclone games would require a separate device category for port 5 maybe?

Old bump, but I would love to see this too. Actually testing lightguns for a frontend and this feature would be amazing.

Hey, thanks for the bump. I haven't ever seen footage of either of these games being played fully with 2 players, but some brief research after opening this issue indicates that the second gun was limited to special Famiclone systems that either:

• Had a second expansion port (a "port 6" if we're following FCEUMM's scheme) for a second Famicom gun
• Used a proprietary set of lightguns with a daisy-chain mechanism

Chiller and Zap Ruder function great already, so dual lightguns is certainly possible. It might just be a bit too much work for 2 or 3 games 😃 (the single-player "City Patrolman" also appears to use a proprietary lightgun input).

Thanks a lot for the update !
