Found a piece of the puzzle I made to myself.
Change the line under /recalbox/share/system/configs/retroarch on the config file back to SDL2 and the game is working at least:
video_driver = "sdl2"
Still the retroarch menu is not being draw.
At least by doing the S#% I also found this:
video_scale_integer = "false"
Which was TRUE and I changed to FALSE.
Now which driver is the one to draw the retroarch menu?
