@voljega I see. That's a shame but understandable.

As pointed by @Substring in other thread the following is fixing the issue 🙂

•retroarch squares : there is a workaround : just remove ~/configs/retroarch/retroarchcustom.cfg Recalbox will regenerate it with the proper values. People using custom configfiles should add the value manually. Might be solved with a retroarch b*mp, no idea
