AKAIO is a public source of the acekard system. So developers can modify and add some nice things to it. People here suggests to use it because it's faster than the normal Acekard OS and it has much more capabilities. "It features better compatibility, more options, more behind the scenes optimizations, better 3in1 support, anti-piracy patching, WI-FI updates, multiple patching methods, faster directory scrolling, more soft-reset fixes, a rewritten cheat engine, an active development team, and much more."
About the wifi plugin...cant help.
The loaders seems to make the acekard more compatible with games and homebrew, son you don't have any kind of errors during gameplay.
I don't know much about all of this, sorry.
