byuu says: Changelog: - GBA: SOUND_CTL_H is readable, fixes sound effects in Mario&Luigi Superstar Saga [Cydrak] (note: game is still unplayable due to other bugs) - phoenix/Windows: workaround for Win32 API ListView bug, fixes slot loading behavior - ruby: added udev driver for Linux with rumble support, and added rumble support to existing RawInput driver for XInput and DirectInput - ethos: added new "Rumble" mapping to GBA input assignment, use it to tell higan which controller to rumble (clear it to disable rumble) - GBA: Game Boy Player rumble is now fully emulated - core: added new normalized raw-color palette mode for Display Emulation shaders The way rumble was added to ethos was somewhat hackish. The support doesn't really exist in nall. I need to redesign the entire input system, but that's not a change I want to make so close to a release.
