corner broken off of little yellow thing...

[DutchDemon]

while installing a matrix infinity modchip in a v7 playstation, i think i broke a tiny bit of the corner off of the thing next to the thing where you attach the sx to. I guess noone could follow that.
ok, if you look here, then below the point where scex is attached is a little yellow thing. i broke a tiny bit off of that.... is that a big problem? i dont know what it does, or if it will cause any harm if i test my ps2 now... what do you guys think?
