Picade for Multiplayer

Hi Everyone,

I have purchased a Piacade for use as a project in the school I work in to engage students in the Raspberry Pi and get them thinking about iconic 2D era games before making their own games in Construct 3.

Only issue is it is a bit of a solo affair and wondered if there is a way to add a second controller (picade console?) or network 2 picades (not sure how many older games would support this).
