Whoa, thanks, that seems to work perfectly! I spent so much time on trying to figure it out that I was even trying to mess with VRAM data to little avail. How did you find it? I'm still pretty new to SNES RAM hacking stuff so I'm not sure what the best tools are to use.
My initial goal was to just play through this Japanese hack on stream and live translate the new event text as I came across it. But then the hacker side of me was like, "You know, I could probably display a bunch of supplemental material live on the stream too (as an overlay) and it wouldn't be as involved as a full ROM hack." So this is more or less a RAM hack/RAM displayer for my stream. I'm hoping to do stuff like this with other games too, especially with games that haven't gotten full ROM translations before.
I actually realized that I could probably partially apply my text to the ROM that's in the emulator's memory and then save that version of the ROM to a file to create a rudimentary menu hack, but it would probably be pretty lackluster. In any case, once I get a few more things squared away I'll probably share my translation text files for anyone who wants to try to do an actual ROM hack of this hack.
