Hello! Download link is not working any more, can you reupload batocera-s812-30-20210214.img.gz file? or send it me in any suitable for you way. I have MXIII-G+ tv-box and now it is just outdated brick - youtube is not updating any more, but I'm sure it can be used again as retrogaming console! Thank You!
