* Fixed missing games in "GameCube Delete menu" if the "GameCube Source" setting has USB priority. * Fixed Playlog writing when using Hermes cIOS v4 (untested) (Requires AHB access). * Fixed EmuNAND when using cIOS revision 65535 (issue 2225) * Added Nintendont support: 1. Select Nintendont's boot.dol folder in userpath settings. 2. Set the "GameCube Mode" setting to Nintendont. 3. Nintendont share some of DIOS MIOS (Lite) settings. * Added sections in the Loader settings (Wii/gamecube/Devolution/DIOS MIOS/Nintendont). * Updated the GameCube game settings to display only the selected GameCube mode related settings. * Updated some menus to support more controller's input: - Prevent GC/CC X and Y buttons to change row number in Wall layout (use d-pad up/down only) - Added GC/CC support to carousel's arrow button - Added GC/CC support to Wall/Carousel continuous scroll (+/- on CC, L/R on GC) - Added GC support L/R and Start buttons in the settings/homebrew browser. - Added D-pad support in listing windows if not pointing the screen. The cursor now moves with the selection (not very good with high Overscan value) (issue 2093) * Changed the StartupProcess to speed up launch time by using AHB access to read config files. IOS argument in meta.xml has priority over AHB detection. * Added IOS58 + AHB support for launching the loader without cIOS (Wii games and EmuNAND still require cIOS). * Added a Loader's IOS setting (now Loader and Games use two separate settings: loader can use 58 and games 249). * Added LibruntimeIOSPatch to patch IOS58 and Hermes v4 to get ISFS access and enable Banner mode, Channel's title and System font with these IOSes (Requires AHB access) * Added a delete prompt if downloaded cheat file is empty. * Force all launched homebrew to reload to IOS58 if available. * Changed Gecko.c to send logs to wifigecko too. * Changed wifigecko IP to send logs to all IP 192.168.0.x * Updated French translation.
