byuu says: New update. Most of the work today went into eliminating hiro::Image from all objects in all ports, replacing with nall::image. That took an eternity. Changelog: - fixed crashing bug when loading games [thanks endrift!!] - toggling "show status bar" option adjusts window geometry (not supposed to recenter the window, though) - button sizes improved; icon-only button icons no longer being cut off
