seedds 6ec201c756 Mario Kart 8 Deluxe (0100152000022000, update 4.0.0, Nintendo's sead / agl / gsys on SDK 4.4.0, the oldest SDK so far): game profile and five general changes. Plays on the Mac and an iPhone from boot through the title's demo race, the Mii pick and the menus into Grand Prix races at 60 fps with sound, and a second boot loads the save. The Mii database (hle_mii.c: the six default Miis every console has, which the game lists at boot without reading the count, none of the console's own, random Miis for the demo race, the editor cancelled) and a MiiModel system data stand-in (0100000000000802 mounted as MiiResource:, written by the host with the layout main's Mii renderer reads: no textures and every shape one degenerate triangle, because the faceline is drawn without a check; the firmware is not the host's to ship, so Mii heads draw nothing). The add-on content cache sized as Horizon's RomFS working memory (its licence is decrypted in a 0x3130-byte heap that also holds the 4 KB the host used to answer). Device save data as a save of its own when main also imports MountSaveData (at boot the game deletes CommonSave:/userdata.dat, which in the shared directory was UserSave's; Animal Crossing, device save only, keeps its island where it was). SDK 4's DeviceSink (command 0xf, 0x130 bytes, byte input indices) and the audio renderer's update lock read off each SDK's own AudioRenderSystem::Update (LockMutex +0x1d0 / +0x1d8, SdkMutexType +0x1d8 / +0x1f0 / +0x1f8: it was SDK 16's for every SDK before 20; sound checked on Big Brain Academy and DRAGON QUEST XI S). The zero cube for a 2D array of fewer than six layers in a cube slot. Profile: render_cond on, a recorded prewarm list from boot into the first race; Breath of the Wild and Animal Crossing boot with their DLC caches resized, host unit tests pass

1	# Game profile of Mario Kart 8 Deluxe (Switch, update 4.0.0 = v1441792). Plays on the iPhone and the Mac (boot, the title screen's demo race, the Mii pick, the menus, Grand Prix races at 60 fps with sound)
2	# Format: see dm/games/README.md
3	# Nintendo's sead / agl / gsys engine with NintendoWare (G3d, Ui2d, Vfx, Atk) and Pia networking, on SDK 4.4.0, the oldest SDK so far (DARK SOULS: REMASTERED is 4.5.0), NVN;
4	# subsdk0 is the SDK's movie library (the menus' H.264 previews). RomFS is mostly Yaz0-compressed SARC (.szs), BFRES models and BNTX textures, which the game reads itself.
5	# Three host parts it needed: the Mii database (hle_mii.c: the six default Miis it lists at boot and never counts, random Miis for the title's demo race), a MiiModel system data
6	# stand-in (hle_mii.c / hle_fs.c MountSystemData: the firmware's Mii heads are not the host's to ship, so every head is empty and draws nothing), and SDK 4's audio renderer
7	# (hle_audren.c: its DeviceSink is command 0xf of 0x130 bytes, and the update lock is an nn::os::MutexType at +0x1d0). Its add-on content (0100152000023001) holds only contents.dat
8	# and version.txt (the courses are in the update): the game decrypts it in a 0x3130-byte heap, which the add-on content cache must leave room in (hle_fs.c romfs_work_size)
