The following Dolphin configurations were used to verify the movie. The movie begins from a boot, not Sram.

Settings
- General
-- Enable Dual Core (speedup): Off
- Audio
-- DSP Emulation Engine: DSP HLE
-- Audio Backend: Cubeb
- GameCube
-- Slot A: Memory Card (fresh and empty)
- Advanced
-- CPU Emulation engine: JIT Recompiler for x86-x64 (forced by the input file)
-- Enable MMU: On

Graphics Configurations
- General
-- Backend: OpenGL
- Enhancements
-- Scaled EFB Copy: On
- Hacks
-- Skip EFB Access from CPU: Off
-- Ignore Format Changes: On
-- Store EFB Copies to Texture Only: On
-- Defer EFB Copies to RAM: On
-- Texture Cache - Accuracy: Safe
-- Store XFB Copies to Texture Only: On
-- Immediately Present XFB: Off
-- Fast Depth Calculation: On
-- Disable Bounding Box: On

Note: it's not clear why this happens, but at least till the beginning of the first race, you should speed up the emulation speed that much, or else the game goes out of sync.

glitched category allows for out of bounds, 100% requires unlocking all characters by getting coins and emeralds
this game has a strange mechanic in which you can bump and try to preserve speed with drifts and counterdrifts as well
rng is maniuplated for more rings and speed shoes when needed, as some emerald and coins are only acessible through rings, some places can be clipped though like city stage top emerald to avoid more collections, rng is not fully controllable as the same item can come along for many frames
the best version of this game for speedrun is PC, so i lose time in the boss challenge after i clip when doing full spins to make glitched laps, the reason is you can make ABSURDLY SHARPER turns in PC version so PC gains time after you need to spin around laps, Saturn version is horrible for 100% because of item collection rules in that version.
however this TAS beats all item collections speedruns and destroys 100% record and then super sonic IL run as well which makes this the fastest radiant emerald completion
ROUTING had help from Sonic R discord
im happy with this run, all players are welcome to improve it and it's a step for more Sonic R TASing into the future.

eien86: Claiming for judging.

eien86: Sonic R is a unique racing game based on Sonic mechanics that reminisce of Mario Kart. While game is available in several platforms, this movie tackles the Gamecube one. The chosen category (100%) requires getting all chaos emeralds (obtained by winning races and their associated 'challenges') and unlocking all characters. The author abuses out-of-bound techniques and achieves a faster time than that of the current RTA WR (11:07) for the same category.
Thanks to Dimon12321 for syncinc this movie. The SRAM flag is falsely set, even though this movie starts from boot.
Accepting to Standard, goal '100%'
fsvgm777: Processing. Dimon12321 is handling the encodes for this one.
