Solved n64 blank screen returns to ES log says ...launch terminated with nonzero exit code 2560!

[mchack23]

well title says it all I guess.
I'm on recalbox 4.0 beta 5 and it's the same with any rom I tried and any emulator/core. I configured all buttons of my ps3 controller (connected via bt stick) I tried different DMT and CEA settings but it doesn't change the fact that it's always launch terminated with exit code 2560.
Anyone know what that exit code means?

snip from the .emulationstation/es_log.txt:

@mchack23 read the readme in every rom folder. n64 games can't be zipped.
