How to set the key position of nebula simulator? Why am I confused when I set 2P?

You asked the right person this question. I am a huge fan of simulation games! Hehe, just kidding. It's best to use the nebula to play games such as the Three Kingdoms War Discipline. I also collected several nebula simulators. Of course I also have version 2.25, but I didn't see what you said! Just one thing, after you set the 1P button, make sure to save it as the default setting, and then click the menu and select 2P to set the button, ok? You didn't select 2P, 3P and 4P in the drop-down bar of 1P, you must re-select the menu -2P. You have a try. As for the dinosaur wars you mentioned, I suggest you use WinKawaks 1.52 as the simulator, which is the best arcade simulator to simulate Capcom's games or all other fighting classes such as king of fighters. I bought two handles and joysticks at home, so I often invite my friends to my house to play. Some people hold the handle, some hold the keyboard, and some hold the joystick (the coolest, like the arcade joystick). Just set the buttons separately, and there will be no problem that a threesome can't be set. Try again with WinKawaks 1.52 simulator! Feel free to ask me if you don't understand anything in the future, and I will try my best to help you solve it. Good luck!
