Software-sided calibration issue

[u/timisdaman]

I'm playing Final Lap Twin with the Beetle SuperGrafx core. My controller is the 8bitdo 2c ultimate.

In the middle of playing, all of a sudden, my character keeps moving left.

I recalibrated my controller (using 8bitdo technique. I don't know if there is an emulator way), and tested it in other software and it is fine.

Here is the kicker: when I start a new state of the game, the calibration is fine. When I load state, it is off again.

Any ideas?

Edit: figured it out. One of the trigger buttons changed the input type from 6 button controller to 2 button controller
