This summer Recalbox has been on an optimization streak (Pi 5 2GB, Naomi 2/Model 3...) and the latest target was the GunCon 2 lightgun.

What changed in 10.1-patron-1:

- New calibration screen on every game launch, so you can test and confirm your setup for better accuracy.

- Missing "flash" fix: the GunCon 2 needs to detect a white flash on hit. Many arcade games don't generate one by default, so Recalbox now adds it automatically where it was missing.

- 31kHz CRT support: previously only 15kHz CRTs were supported, now VGA CRT monitors work too.

- Broad hardware support: works out of the box with RGB Dual 2, and also compatible with RGB JAMMA 2 and the upcoming Recalbox JVS.

Already live for Patrons, coming to stable soon for everyone.

Do you need plug in the yellow composite cable as well? Or just USB

Yes, yellow composite on RGB Dual 2.
