There is a Famiclone lightgun game called
City Patrolman which I hope you would consider supporting in FBNeo. Currently it is not playable on any emulator on the Raspberry Pi (which is my weapon of choice). I think it uses Mapper 405 and I think this because when I tried to run it with FCEUX on Windows, it fails to load with an error that iNes Mapper 405 is not supported. I have been told that it runs in Nintendulator.
Sourcing the rom was difficult, but I understand the rules forbid me from telling you where it can be found.
This youtube video describes the game in great detail. :
