Floob please help me!
I tried 3 different mame emulators:
1) the first mame, the default mame4all, cant save e cant use dpad
2) advmame is too slow and no way to use it
3) mame libretro, ask me to select a core and other things in a greenish menu. Is that a part of retroarch? Are there instructiins on how to use it?

Thank you so very much. This world is so very difficukt for me!
