Been out of the game for a while. Have a soft modded 4.0 system. Do I need to upgrade to 4.2 or even 4.3 for any reason? If so, what is the easiest way to accomplish this? Looking to finally get some newer games, and don't wanna get stuck or have issues. Some sites say no need to upgrade from 4.0 in terms of games. The guide here says 4.2 is the earliest 'homebrew friendly' SM. Whats the scoop? I did do some reading on my own first, as always, but am getting conflicted answers in different posts/sites... Thanks in advance!
