Some of the games I tried

*In these Super Nintendo games that I'm playing, there's a glitch that controller number 2 controls player 3 and 4 at the same time using the core Snes9x 2010 1.10

Super Nintendo games:
-Super Final Match Tennis
-Go! Go! Dodge League
-Kunio-kun no Dodgeball da yo Zen'in Shūgō
-J.League Excite Stage '96
-Bakutou Dochers

Sega Genesis (Mega Drive):
-J.League Pro Striker 2
-J.League Pro Striker Perfect

The problem was solved, just go to advanced settings and then to emulator settings and set the LIBRETRO SNES9X emulator as default, then configure so that each of these games runs on that core, within the game just go to the emulator option (hotkey + B) and configure controller 2 with multitap and have fun with 4 friends.
