Help configuring NES Controllers using 4nes4snes USB adapter

[trk55449]

Hello all,

I’m building a NES emulator using a Raspberry Pi and am having a problem getting two controllers to register in Emulationstation. I’ve wired the original controller ports to this device: http://www.raphnet-tech.com/products/4nes4snes/index.php and even though I have two controllers plugged in, it only registers one. Also, it will detect one controller at a time in each controller port and it works fine, so I know both are working properly. Can anybody give some advice on getting this configured to use two controllers?

Hi trk55449

I used this 4nes4snes circuit as well. Since version 2.5 / 2.6 the controller only recognizes 2 axis instead of 8. (before the circuit was recognized as a joystick with 8 axis and 32 buttons).

This seems to be a Problem with the newest generic joystick-driver.
Sadly i havn’t figured out yet how to downgrade the driver or how to get it to recognize 8 axis again.

for the working configuration you can have a look at my post: https://www.petrockblock.com/forums/topic/has-anyone-used-the-raphnet-4x-snesnes-usb-adapter-circuit/#post-87027

Please let me know if you figure out how to solve the problem ;)
