Seems like a pretty good handheld so far very little issues have not used the kcard yet but homebrew & pirate carts don't have the compatibility rate of genuine gba games
the one on the left seems to boot and play ! but the one on the right seems to boot and crash as soon as you click the game...
only ps5 updated to latest firmware can go on psn, jailbroken ones just don't use psn or they risk getting flagged or banned, altho spouting profanity in online play alredy does that
