Hi.
I am running recalbox with retroarch and am having an awful time trying to figure out how to change resolution on all emulator cores in retroarch.
I am running an arcade cabinet with a crt wellsgardener monitor which has 800x600 max resolution. Running a hdmi cable from rpi3 ti hdmitovga converter then Into the arcade monitor.
I figured out a command line in config.txt on how to get emulation station showing on the monitor, but when I run any core from retroarch or fba I get an out of sync error.
I have messed with many different configs in config.txt and recalbox.conf file but I cannot work out why it is doing this.
The hdmitovga adaptor works as I can run an image I have on retropie fine with adaptor and all looks good.
N64 works fine all the rest of the cores drop out out of sync.
Any help please?
