I had red screen up to now, after some reading and a lot of trials here is what i did to make it work. I've set my screen resolution to 1366x768 then i've put icon, label and/or banner in /input/game_name, then i've run baner.bat and then i've run make_xx.bat, done.
I also tried New Super Ultimate Injector beta26 wich was released on reddit some time ago, it's a beauty and in general it seems to works like a charm but i find the old snes to be missing features, namely to be able to zoom screen and keeping aspect ratio, i also find it rather annoying to be able to change the screen feature only when building the game. So for now I'll stick with the old tools for snes thus they are more painfull to work with. Don't know why but my game do an error upon exit and restart the 3ds i only tried with snes9x on a single game so far, but it saves and works well so it just waste 10 seconds anyway.
