- So I have a supergun already but wanted to add an easy way to have 3p and 4p for avp and d&d. So I ordered the add on board for the has supergun and plan to stick it in a box. Got a cheap box off amazon and a plate for 2 sub 15. Found some cheap sub15 ribbon extensions. So last piece is the cps2 connector. I plan to mount the little pcb so the cps2 connection on the board is accessible. I’m waiting on the board and cps2 adapter so I’m just preparing the rest of it.
