At last.

JJFTails done what I should have ages ago and big kudos to him for that. Check out his Chaotix Art Editor in the utils section.

I would also like to use this newspost to remind some people that ROM hacking is about having fun and learning new things, not being envious, nor aggressive about your/others work. It's a hobby, and it doesn't matter how much ASM can a person hack or how awesome his graphics are, it's the work, progress, and most importantly, fun, that matters. 

To cut a long story short: hacking is supposed to be fun, not a subject of stupid flamewars etc. I hope you agree with me on that matter.
