OK, since it's 7am and I DID NOT GO TO SLEEP AT ALL LAST NIGHT because of this amazing find... I'm just gonna post some pictures and junk and leave you to ponder its consequences.
FRESHLY TAPPED GALARIAN
Yep, long story short, I managed to decrypt a copy of SwSh and started poking around at its texture files. There I found only the start of all of the Galarian text in the game. This represents the last couple hours of poking around, yet only a small fraction that is left to be found.
With this now available to me, the next goal is to start including clean scans with the Galarian Word List, as well as have them to use in the forthcoming YouTube videos about them. Good times had by all! HUZZAH!
