Kugelblitz On the 5.26 build with the OGA 1.1 I can’t run any NES games. Manually switching emulators/cores also does not help. Both return to a black screen. All other systems seem to work (and the ROMs work fine on the RPi and X64 builds).
Kugelblitz Found the problem: Had the Romset with missing headers - Mesen works fine with them, but Mesen is not on the OGA. Adding headers did the trick. Followed this guide: https://nerdlypleasures.blogspot.com/2020/04/fixing-nes-headers-and-renaming-nes.html
