the problem is not the mame.cfg, I can edit that file with Winscp. loggin: root and password: ……. but in that file I can edit some controls but not all. only you can edit all within a game of MAME4ALL as you can see in the picture costs. I read in the forum that these controls keeps the mame inside and can not be edited. retropie in 1.9 as it was not necessary to be root, if kept, but now the problem of being tenenmos root
