The original Parallel Worlds patch used the 1996 rom to patch to, this new Parallel Remodel uses the US rom done on 23rd of august 2004 (no header). The difference is that the 1996 has a header. So you have 2 options, search for 2004 rom, or remove the header of the 1996 rom, and then patch.
The only new music is in Darunia's cavern dungeon.
Yes, I know. The original authors were not english native speakers. The story is not only grammatically problematic, but it is also questionable regarding the story. I was using the 1.0 version of PW, so that's
the reason. The 1.1 has some texts fixed. The rest of the game is however less problematic than the intro, but I agree that everything regarding texts is a weak point of the game.
Another problem of the game is that it is locked, and I never decoded the text (if one letter is changed in the text, all text pointers and all the text data is changed), which is way to much to allow any text editings.
The only version of PW that I had was 1.0, and had it already edited to some point. Once I picked up 1.1, the hex data was changed and it didn't match to the 1.0 in some points. Ive heard there were only text differences, so I continued with the 1.0.
The only problem is that the file is heavy locked, otherwise I could just fix all the texts, add sprites in some empty dungeons (like Impas ways), change sprite blk and add new sprites (Parallel Tower), fix Link's sprite gfx wise, fix the title screen (still bugged in most emulators), fix the display faults in some staicase passages etc.
So I had no choise but to lower the standard for this game, and will rather raise the standard in my next project, because PW is very difficult to edit.
I've just realized I can port the new data to 1.1 version with text, titlescreen and other fixes. Will probably come up with 1.1 version in the near future.
