With System Menu 4.3 just released, we've been forced to put out a maintenance update of Riivolution for those unfortunate enough to have updated.
Luckily for you guys, this means you get a sneak peak at the latest Riivolution, which wasn't due for a release for a while longer. Besides generic stability improvements, the new version now makes it easier to replace files on the fly with RiiFS. A new native server is available for Windows, Mac OS X, and Linux that now automatically connects over a LAN, removing the need for an SD card or special XML. See the changelog for all the new features and changes.
Unfortunately, Nintendo's update has disabled Bannerbomb and the Homebrew Channel. This makes it harder to run Riivolution; until any updates are available for those programs, Riivolution must be run by using either Indiana Pwns or Smash Stack (only one time is necessary for a channel install).
