some one will probally make patches for it just look at daigasso band bros

 

Yes, it will more than likely be possible.

 

darkcrudus, first you replace the actual audio, thats the easy bit. Then you make a tab of the song and convert it to Guitar Hero's note format and insert it into the game.

Well, since the game hasn't come out yet and isn't widespread to everyone (and considering there isn't even a dump of the game) I'd say it's unknown as to whether or not custom songs are possible.

Ask this again in a month, then I'm sure someone would have a more definite answer.

 

is you can do that
that would be pretty awesome

 

I could see you being able to port med and easy songs from guitar hero and rockband. Should be interesting to see the progress with this.

 

Ummm, what

 

Everyone sees to have missed the fact people would have to be willing to recreate songs for the DS, and without any software for this at the moment, it would be quite hard. All the custom songs at the moment (and the tools used to create them) use 5 notes, rendering them incompatible (I assume, unless you can just miss out the 5th fret when playing).
Anyway, it would be a good opportunity. Though I'm looking at GHIV Wii really. VV confirmed DLC will be downloaded onto your SD card, which means songs will be read off there too. Anyone with a brain will realise what opportunities this creates.

 

There's a button hack for the Guitar Grip so all you really need is:
DS
Flash Card (that runs Guitar Hero: On Tour)

I'm waiting for better configuration of the buttons >_< Y which is at the bottom middle when the DS is vertical is the far left color (cant remember off the top of my head) when X should be Y.
