Multitap issue

[Dancarmo]

Good Afternoon

I'm new with recalbox, bought a raspberry pi 3B 2 weeks ago and it came already configured with the version 4.0.0, with emulators and roms. I use 2 snes controllers and 2 ps2 controllers (usb)

The problem i'm facing is with the snes: I can play, for example, bomberman or micro machines with 4-5 players without any problem. But other games, like Looney Tunes B-Ball it doesn't recognize that there is 4 controllers. In PC, using znes i could play with 4 players, so it's not a rom problem. Any suggestions of what should i do?

Thanks
