ROM Hack Sunshine Island rom alteration

[arsdraconis]

The english version of sunshine island had the wifi feature completely removed amongst other thing.

Would it be possible to go to the japanese rom, unpack it and replace all the japanese text with the one from english rom in the same manner of undubbing to participate in the japanese wi-fi rankings?

I guess it depends on how the two games store their text, images and other things.

But, the WiFi menus probably wouldn't be translated even if you did the repacking ~ because if they removed it, there was no need to translate it.
