@takochan better go on the discord server (link at of the page) and ask, but I bet rpi4 isn't ready for anything yet, it was really a botched release, from both software and hardware point of view

@voljega Looking forward to FB-Neo. I understand that Beetle-HW cannot be supported on current hardware (RPi3 & OdroidXU4). The reason I mentioned it was that (according to a RetroPie forum) RPi4s supports Open GL ES3.x, thus making a Beetle-HW core viable. I hope this is possible, but I have little technical expertise on this topic so I thought I'd ask the RecalBox dev team whether they had plans to incorporate it in the new builds.
