Well, I don't know if it's the problem but I just found out that my intellivision games are not working any more... Blank screen and back to the menu.
Mame games seem to be OK.
About Apple, I tried with games zipped and unzipped by adding extension .zip in the es_systems.cfg

I found the problem about the intellivision games...
It comes from the keyboard hack files I created.
I removed them all and replace the emulators.cfg as well.
Now I can launch them. But without the keyboard hack !
