Thanks Maxtram! that'd be really useful.
Anyway, I decided to upload the script for those who want to help us, it comes in two files:
the script ripped from the site
and the script where the english text should get inserted into
https://www.mediafire.com/?7ioicl9il4c3nwa,74z0j2t92aota1c
The idea is to basically insert the ripped script (scriptTXT.rar) into each of the files in the other script (they are a lot, so any thing like a program to do it automatically will work). Afterwards i all comes to trial and error.
Basic steps:
1. Identify the dialogue for testing purposes, and add it to main.c.
2. Replace the text with some garbage (so it will actually fit in the rom),
and create a patched rom.
3. Try to run the script in the game.
4. If the game hangs, then you probably messed up the jump addresses.
I can't be bothered elaborating on this right now, so let's just pretend it's not a problem.
5. Then you putting the translated text in line by line.
I think TLZ or whoever should really look into inserting scripts into
the empty space at the end of the rom, otherwise the last step is
extremely tedious.
Though someone could start by copying *.txt with 1kb, the procedure is
open scriptTXT and locate a 1kb file
locate the file with the same name ( by name I mean the numbers) and replace the text
rinse and repeat
Oh yeah, Ritchburn's github contains the latest files
