I changed the language switch in the savegame to use the otherwise unselectable english language text.
I haven't tried playing further, but everything seemed fine until the first savepoint.
I saved at the earliest time possible in the game, which is like 2 minutes in." -redfalcon
Using redfalcon's notes (code below) I used a save and changed all the files to english.
The result are these Easy, Normal, Hard saves modded to hidden English setting, with a Gallery.
It's at the first Save Room after the Ship and Navigation Room.
It was the only way I could get it to work permanently.
Sorry, It's not a full Gallery I couldn't get the code I found online (shown below) to save. If you know how let me know.
