Short answer: you can't.
Long answer: The replays are not saved as actual videos. They are saved as game files that let the game know what happened and when (like a script for a movie).
you record it with a capture card, upload it to your computer's video editing software (if you have one) and crop.
It depends if you insert your SD card into the computer and the file type is not recognized you must upgrade your software. I haven't been able to watch my replays because I haven't upgraded my graphics software. So if you don't upgrade you can only watch it on your console.
You have to have an SD card, like for a camera. insert it into your wii and proceed to brawl. go into your Pictures and replays and select which one you would like. then hit down and there will be an SD card button. Click this button and you will be able to transfer your pictures/replays to your SD card. Then insert your card into your computer and import said material to your computer. from there you can upload them to youtube. i hope i helped
on a website
You can't get it for the computer. It's a video game, not a computer game.
Yes, search Super Smash Bros. Flash on Google
If you get a Wii emulator or Gamecube/Wii emulator, you can get a Brawl ISO and play it like that.
You matches have to be short enough, I think it has to be less than five minutes long. At the end of the match, when it shows the winner and the stats, you will see a "Z replay" icon. Press Z, and it will let you save your match.
you can play it on a website called scratch
Sorry, there are no smash brothers brawl toys.
You can only install Super Smash Bros. Brawl on your Wii with a Super Smash Bros. Brawl disc.
No you cant so dont bother trying
