Hi 8bitRetroLove, there's already work done on games like Terminator 1 and 2, Robocop 2 and 3, etc., which are on romhackplaza: https://romhackplaza.org/romhacks/famicom-expansion-port-controllers-support-collection-nes/#. Games like Nightmare on Elms Street and others work perfectly with the 15-pin expansion port. If they're not working for you, it's probably due to the type of controller you're using. There are new Chinese controllers sold on AliExpress with 15-pin outputs that don't work very well because they're poorly made. If you're using older clone controllers, most of the new ones work perfectly. That might be your problem.

I won't bother writing for now. What games I wrote about? Please make them if you have free time. Of course, there's a shortage of games like these. Please keep posting. Don't give up.

Thank You So Much Max!!!  More games are missing: Antarctic Adventure, Big Nose The Caveman, Bomberman 2, Robocop 2, 3, Dizzy The Adventurer, Dragon S Lair, Flying Hero, Heavy Barrel, Home Alone 1, 2, Micro Machines,The Simpsons vs. Space Mutants, Terminator 1, 2, Ultimate Stuntman, Tom and Jerry Japan,Nightmare on Elm Street, A
