As you know, this summer is all about optimization at Recalbox. After work on the Pi 5 2GB (article here) and on Naomi 2 and Model 3 (article here), the team turned its attention to the GunCon 2 — the gun that lets you play Time Crisis, House of the Dead, Duck Hunt, Confidential Mission… — plug and play with Recalbox since the release of the RGB Dual 2.
While the experience was generally solid, a few issues could crop up: missed shots, rough calibration, needing to crank up screen brightness for certain games to work properly, notably on Dreamcast… The overall experience was good, but we wanted to deliver rock-solid support.
After several weeks of work — and a certain Recalbox JVS that got us digging back into gun cabs — we're happy to announce that the GunCon 2 now works wonders with the 10.1-patron-1 update!
We've added a calibration screen every time you launch a game for your GunCon 2, letting you test and confirm your setup and calibration for optimal accuracy.

To get shot detection accurate up to 99%, we've also added a white flash that lights up your screen when you pull the trigger (something you may have seen natively on certain cabinets). The GunCon "sees" the screen loud and clear this way, and the shot gets detected. No more need to crank up your screen brightness!

As you know, the GunCon 2 is compatible with 15 kHz CRT screens (the old-school cathode-ray TVs that used to sit in every living room…); compatibility is now extended to 31 kHz monitors (the CRT VGA screens that notably powered our old PCs…). Plenty of room to enjoy your gun on this type of screen with zero compromise!

These optimizations are already available to Patrons via 10.1-patron-1, and will be coming soon to the stable release for everyone. In the meantime, check out the video below for a few clips from our testing on these optimizations.
