Thanks for your help. I really appreciate it! Is there a tutorial for character replacement?

Thanks for your fast response!
What kind of glitches do I have to expect? Game breaking glitches or just some minor graphic glitches?
Is it also possible to mod the game and play it on Dolphin (on PC). I do own a Wii and the original version but it would be way easier for me to do it that way.

Hello there,

I just joined this forum to ask a few questions about the "hackability" of Super Smash Bros. Brawl.
It's been a while since I played the game and I actually stopped before the whole hacking was possible at all.
Now that I see that there are a lot of great models for characters I am thinking about going back to the game.
Being a huge Sonic game I thought how awesome it would be if you could replace most of the character cast with Sonic related characters (that can be downloaded from the database here).

But is that actually possible?
Can I replace or even characters in/to the game? Can I change the pictures in the character roster? And what about the stages: are there actually new stages or stage replacements out there? Can I add new stages or do I have to replace them?

As you see, I am a newbie on this topic and I thought I'd just post my question here before I actually start downloading those hacks and modifications.

Thanks in advance,

Dynasty
