Hi!
I'm trying to override this setting for Amiga 600:
uae4arm_resolution = "320x256"
So I put .core.cfg into /recalbox/share/roms/amiga600
with this simple content:
uae4arm_resolution = "640x256"
... but nothing changes 
Am I doing anything wrong? The instructions on the wiki seem to be quite simple 
Thank you in advance!
