* Use savedata FS commands from LibHac * Add EnsureSaveData. Use ApplicationControlProperty struct * Add a function to migrate to the new directory layout * LibHac update * Change backup structure * Don't create UI files in the save path * Update RyuFs paths * Add GetProgramIndexForAccessLog Ryujinx only runs one program at a time, so always return values reflecting that * Load control NCA when loading from an NSP * Skip over UI stats when exiting * Set TitleName and TitleId in more cases. Fix TitleID naming style * Completely comment out GUI play stats code * rebase * Update LibHac * Update LibHac * Revert UI changes * Do migration automatically at startup * Rename RyuFs directory to Ryujinx * Update RyuFs text * Store savedata paths in the GUI * Make "Open Save Directory" work * Use a dummy NACP in EnsureSaveData if one is not loaded * Remove manual migration button * Respond to feedback * Don't read the installer config to get a version string * Delete nuget.config * Exclude 'sdcard' and 'bis' during migration Co-authored-by: Thog <thog@protonmail.com>
