So I've run into a very interesting situation with the Magic School Lunar fan translation: one script is too big. I've gone above the RAM budget for the first time in the start of chapter 4. The original is the largest script in the game, at 162KB, and the inserted English script is hitting significantly above that. It seems the game crashes on load if the generated script file is any larger than 170KB, and the generated English version is currently 198KB.
One option would just be to get ruthless with editing and try to get the character count for English down to around where the Japanese is. I think there's room for another approach though; there's something like a spare 30-40KB in the game's kanji font, which is mostly blank now. It should be possible to relocate some of the excess script data from this chapter into that, since it's otherwise just wasting RAM.
