I know 1.18 was the last offical update, but I'm seeing so many other ones. Is it worth upgrading to any of the later ones? and if so which one is the newest or best. Thanks in advance!
1.18 is the last official update, if you try new games many of them will not load, that is the only time its worth updating. You can update to unofficial 1.19 or 1.20 or try ysmenu (this is a different operating system - homebrew) Remember there are 36 different R4 cards, don't be tempted to update to one of the other firmwares from these as it will not work.
