I think it's safe to say you're not going to find Magecraft or whatever the one member's name was.
The wonderful people at the Whirlpool
flamed the hell out of him a decade ago for "stealing" a more experienced member's project (flaming wouldn't be tolerated here).
More relevant to this topic, it would not surprise me if this was stored with event data between the text. Definitely not beginner friendly, and I imagine it's a good reason why nobody's finished translations of the SNES games.
I tried myself to do RPG Maker 1 for SNES. Take a look in the editor at the things an NPC can do: walk in each direction, turn in each direction, yes/no prompts, etc. Each of those has a hex value. And even for the "text" opcode, there's probably more control bytes for text length, windows, etc. Even if you made a custom text dumper/inserter that could expand and relocate the event data, I'd guess that due to the editable nature, you'd still be restricted in how much you could expand the text before crashing by making the data take up too much SRAM.
(I'd thought about doing DTE for RPGM SNES, but then I realized that'd make editing the text input windows a real problem)
