Yes absolutely. Use whatever cIOS you like to load games. As for the issue with resolution, not sure why it would make a difference. But if it works with 222 then use 222Lastly most people use 249 as a default, IF 222/223 work on both tv's is there anything wrong with doing thing backwards per se. Instead of using default 249 w/ my usb loader, default it to 222/223 and set individual games that would work better on 249 to use 249. I only ask because it's suggested and more popular to default 249. But switching tv's makes it a pain in the butt.. Thanks for reading,.
