I tested all the game you listed and player 2 work fine in all of them. No random press observed.

Are you using a NES or a Famicom?

Also I do not have any control about the quality of the stuff on AliExpress. I think your cable for player two is defective.

I'm using a famiclone, that has nes port, I'm not sure if it has something to do with the port, i played double dragon 2 but there's no problem with it

i tried to reset the core, with selecting none for mode, my everdrive automatically press with start button
