After a quick google it looks like the Wiinja.
Though it says Wiinja on the other side, so I can't tell for sure with this photo.
Depending on the version, it's probably not possible to upgrade it. Also, most of the early generation modchips stopped receiving updates a long time ago so don't get your hopes up.
My guess is that you can just remove the chip, making sure not to short out any wires or damage any contacts they are soldered to (properly desolder them or clip the wires and insulate them, don't just pull them off).
Then either go with your softmod, or buy a newer chip that does still get upgrades.
