Me again 
I've finally bought a Xinmotek encoder for all the buttons of my cab. This way I can plug it directly on the usb port and it's easier to switch from rockpro664 to raspberry.
The buttons are now working.
But I have a problem with screen resolution... My cab has a 19" screen with 5/4 ratio and a hdmi/vga adapter. The option global.videomode isn't available for the rockpro64, I can't set it to DMT 35 HDMI like for the raspberry.
I've tried to change the value in /boot/extlinux/extlinux.conf : video=HDMI-A-1:1280x1024@60 . It seems to be respected only at boot.
I see the game list in a good resolution but when I launch a game, the video is deformed and not fitting all the screen (only like 40% of it). Moreover the resolution doesn't stick to 1280*1024 , it turns to 1024*768
I've also changed some values in recalbox.conf : global.ratio=custom
In raspberry there is the file /boot/config.txt to fix the screen ratio and resolution but it doesn't exist for the rockpro64
I'm lost now...
