What are you talking about?
Simple if you have an original Neo-Geo joystick, you can build an adaptor with this pcb i linked to play with it on PC maybe even on PS3.
You could also install it to the stick and do a USB connector within the joystickcase. All you have to do is a little wireing ( like you did with you selfmade joysticks ).
If you have a NGX joystick you could also place this pcb inside for better PC support and also add a DB15 port to the case.
So basicly im telling if you have a NGX joystick you can invest 21 C$ ( with shipping ) and maybe 1 $ for the DB15 and have also the possibility to connect it to MVS, AES, PC, PS3, NGX. All you need is some soldering skills.
Nothing against your sticks, just telling some options.
Of couse if u dont like the NGX stick, your sticks are a great option.
Of couse if you dont like the NGX stick your sticks seem to be an awesome option.
I made me an adaptor and can use all types of NG sticks or NGCD joypads on PC.
