Link to the Past GBA text editor?

[SmithSmith]

I found a text editor for Four Swords, but not for LttP. Is the text data in LttP compressed in some way?

Off the top of my head I don't know but when I have looked at the game in the past then 4 swords (bundled with it for those unaware) is basically a separate game doing its own thing with its own formats.

Have you tried relative search?

That utility only seems to be able to pull up the Four Swords text

Usual things there are then a non relative encoding, 16 bit encoding (I presume you did not try that) or compression. The latter being by the far more likely.

Compression search is kind of a thing, and if it is BIOS calls you may also have SWI logs but most things there beyond the simple decompression tools are going to be graphics or maybe audio oriented. You might still use a SWI log to guide a decompression effort instead of jumping right to the assembly debugging.
