This is how the demo mode behaves on actual hardware.

It doesn't do it if you disable the default EEPROM provided in the driver, so it's probably something in there that the World version doesn't like.
I'll see if I can create a default EEPROM which still works and doesn't cause this bug.
Edit: nope, it seems it doesn't like the values written to the EEPROM after calibration.

I've traced the version it first started happening, 0.143u8.
Looking at the files touched during that update, I can only conclude either 68k change(s) or Core Input Changes might be at play.
**EDIT** I was mistaken
Issue I found was related to the nvram as it changed locations in that version "nvram\bbusters.nv" vs. "nvram\bbusters\eeprom."
So, in essence, I was using the nvram I had made before the regression and not deleting it until it forced it to not be seen by moving it's location.
The 0.128-0.129 regression is correct, traced to 0.128u4

|Fixed. Please be sure to delete your current contents of nvram\bbusters in order for it to work properly.|
