I wanted to report a possible bug.
After uptade 12.3, my Sega naomi and Sammy Atomiswave systems stopped working. I use Retroarch with the Flycast core. When I try to run the certain games, the Dreamcast Bios screen opens.
I tested the same game directly via Retroarch and it works perfectly.
I did a test with version 11.17, using the same roms and emulator/core versions and it works perfectly.
PS: With the new beta version of LB, the bug persists.
