This is a converter that allows you to connect PSX (1 and 2) and N64 controllers to USB and use them on a PC. I confirmed that it accepts input from all buttons and sticks by connecting PS2 and N64 controllers and using Joy to Key. However, it seems there are compatibility issues with N64 controllers, and some may not be recognized properly. Connecting a PS controller might work in some cases. Since I only tested the PS side with a DualShock 2, there may be compatibility issues depending on the controller. I remember there was originally a sticker on it, but I think it has come off.
