Are you guys using actual PS2 pads for current gen systems or some aftermarket, third party controller? If the former, hook a fellow member up with a source?
Using the a brand new original Dualshock 2, with a PS2 to PS4 converter. Best decision ever.
For the controller, I ordered it on Ebay for like $45 brand new. I was skeptical because there are so many 3rd party, knock off, or refurbished ones out there. So I went with one listed as brand new, from a 15 year old warehouse seller with like 30k positive reviews at 99%. Had pictures to view in advance, good rep, all that. It arrived in 3 days and was legit brand new in the OG box and all. The title was
Official Authentic Sony Brand Black Dualshock 2 Controller NEW sealed SCPH 10010 so look for something similar on Ebay.
For the converter, I was originally gonna order from Play-Asia, but ordered from Amazon for the fast shipping. I got it here-
https://www.amazon.com/gp/product/B01H5PCYYW/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1
Could have saved probably $10, but I trust Amazon more and prefer the fast free shipping also.
It's as easy as a connect, plug, and play.
