Blasted through story mode with my mii, unlocked all courses, I barely touched "play golf" and "solo challenge" so if you simply want just the courses unlocked, this should do the trick. Extracted with JKSV.
btw i feel this a good time to remind you guys that sea of thieves was made by rare, who also made DKC1-3 and DK64, alongside banjo kazooie and conker's bad fur day
