When launching the game just starts randomly blinking then its splash screen, then a one-color background (I could not capture the moment with the splash screen), but in general I could not launch the game normally.
If fixing Gngb is not possible due to lost source code, or other reasons, maybe it will be good idea to port mGBA in KolibriOS.
