When playing an Atari 2600 game where a bezel is not available, the bezel for BurgerTime is displayed. Running RetroArch 1.8.0.
Somewhat related: I discovered this issue when Centipede was displaying the BurgerTime bezel. Looking into the problem, I realized it was because my Centipde ROM was named different from the game config file. My ROM was named "Centipede (Japan, USA)" while the config file was named "Centipede (USA)". According to the most recent No-Intro DAT file, the name of my ROM file, "Centipede (Japan, USA)" is correct. The most recent No-Intro DAT file can be found using the Atari 2600 entry here:
