PS2 MAS superpro stick button repair help

My Square button broke on my MAS super pro stick. probably just needs cleaning.

I opened the bottom of my MAS stick and I have no idea how to take out the buttons for cleaning. Anyone know how?

What do you mean by broke. The button doesn’t register? If that’s the case you’re going to have to replace the cherry switch on it. If I’m not mistaken you will have to desolder the switch, take the old switch out, and resolder the new switch. Sounds easy huh lol.
