EclaireXL has diverged a lot, use this for other platforms for now!
Fix menu control with stick on 5200. Add escape support by pressing both stick triggers. Make accidental reboot harder on 5200. Now reboot is on right stick + trigger on both platforms. Still on trig2 for a800 which only has one fire button.
Added usb polling
key control in menu. escape to exit
Removed delay
Better cartridge support for 5200
Started merging in 5200 firmware changes. A800 firmware tested working. 5200 firmware not working, but likely a small fix...
Fork of firmware for 5200 - will be merged back in soon...
