===========================================

I also used the NullDC trick to try and fix the clock issue. (It edits dc_flash and makes a copy, which you rename and place in the BIOS folder)

reicast_input = "1" in /opt/retropie/configs/all/autoconf.cfg

Emulator: Reicast

How to replicate the problem: I ran the joystick config via command line (reicast-joyconfig) and the joystick was still functional. It was only the joystick, no buttons worked. I had a working joystick until I ran the autoconfig in RETROPIE SETUP.

I've confirmed my controller is at event0. At this point all I can guess is that this controller is just not supported. The config file looks quite a bit like a 360 controller's config provided on the wiki.
