The unlicensed game Lethal Weapon (Ch) [U][!].unf works in FCEUX and Nestopia; however, the Zapper support only works accurately in FCEUX. Both react to the Zapper trigger. But, Nestopia seems to register the hits only 20% of the time.
Since there is no wiki page on mapper UNL-TF1201, I used the FCEUX source as a guide to add a mapper to my emulator. Interestingly, the result behaves likes Nestopia. This suggests that the Zapper implementation in FCEUX is different from the wiki description. Anyone have any idea on how I can improve my Zapper implementation to enable this game to function? Lethal Weapon (Ch) [U][!].unf actually looks like a really awesome Zapper game worth supporting.
