Why can I scan games that I don't have cores for?

I am trying to find out why my lakka shows games available for ps2 and game cube on the carouselle but i cant find cores for those systems…im on a pi4

That just means it matches our databases. Usually, it won’t let you scan games that don’t have at least one matching core, though…

Is there a core that specifically works for gamecube games or ps2 as maybe im just missing it thanks

gamecube is dolphin, PS2 is Play!
