ROM Hack Question RE: changing intro song

[SS4]

Hey guys, I was just wondering what tool(s) i would need to change the intro music of One piece Gigant Battle and replace it with the one from the Japanese rom?
Any help appreciated.

Thx.

Erm.. I'm not sure if it would work in this case, but surely you can just unpack both roms, find the intro video file in the JP version and replace it with the same file in the EU version?

Or wait, is it just music - not a video?

Anyway I'm sure you'll figure something out xD
