errr i don't think so... i think its more likely becoz its a E 1.2 rom.. instead of a U 1.2 rom
and no, hes wrong.
whether he created them or not, they are still made to replace the textures in a copyrighted product, claiming ownership on them could constitute theft of copyrighted art, as in the end, they are still made to resemble the original work.
you'll find that copyright law, is vast enough to allow nintendo to claim your work as thier own, becoz of the method of how you created them in the first place. ie dumping the original textures and saving them as modified versions constitutes copyright theft.
technically the same goes for Plaguerism,.. when you copy a piece of information and just change a few words. its the same thing.
get over it.
you can't claim ownership of it, in any way. its not yours, and neither is the game that it works on.
really who cares where you can download it from as long as its getting to people... sometimes i wish people weren't as materialistic as such to give a crap if someone mirrors thier work then has a crap about it.
get a life. theres plenty of other people who could've done this pack better, who wouldn't give a crap at all about others mirroring it.
