8BitDo Retro Receiver for PS1, PS2

Its amazing, like spiderman but without the strings!! Basically i use mine all the time its really cool to use the sn30pro or pro2 with it. I highly reccomended this

I own a Brooks adapter that connects with PS3 controllers immediately, which are critical to playing PS2 games that use the pressure sensitive buttons. I was hoping this adapter would do the same and look better in my setup, but no. Still good to connect other controllers.

Went on Reddit recently regarding my only 'trouble' i had with taking a full potentional out of SCPH-39004 - at least as far as my needs go; that was being unable to track down a decent *OEM* Dualshock 2.
Fellow Redditors closed the gap i was having with advice to go 8BitDo RR route, and since i'm a PS4/PS5 user that advice turned out to be golden!
I have multiple Dualshock 4s laying around with two Dualsense 5s being actively used so i tried both routes, and conclusion is - both have spot-on connectivity with 8BitDo dongle and work flawlessly but my decision landed on one of my Dualsense 5 joystick just because there are xy times more USB-C cables around my house used to charge the joystick, finding a micro-usb cable has started to be a pain in the a$s.
8BitDo RR dongle for the win!

Works great on PS2 Slim, pairing is really easy with a Dualshock 4. Only thing I'd change is make the LED green to match the PS1/PS2 power LED color, the blue LED doesn't match.
