Tux Guitar and 64 Emulators for homebrew wii!

I was wondering if there's anyway I can run programs like Tux Guitar through the wii Homebrew it would be awesome and good to store tabs.. And I'm also having a problem with some 64 emulation on the Wii I was really looking forward to getting Conkers Bad Fur Day, Vigilante 8, and the Banjo series for 64 running only, not very many but if anyone knows good working roms or if it's just the Wii64, I'm not sure how to go about this and it took me almost a week to figure out the homebrew it's self without help then I found out about these forums. I've been getting alot of ISO from here and Roms. I also got one last quick question. I also use Nintendont.. But one of the games "Digimon Rumble Arena 2" Does not display in center of the screen the entire screen goes to the left leaving a big black bar on the side of the screen. If anyone can help me with these issues would be greatly appreciated thanks for reading and your time!

Tux Guitar is open source so could be ported if it has not already but this is not a good place to ask for that as we are mostly users rather than programmers, there is the odd exception to that.

Emulation it will just be the emu in question, N64 emulation is difficult at best though, there may be an alt emu that you could try maybe, not sure if Retroarch for Wii includes N64 or not though as I have not had me Wii out in some time.

Nintendon't I would need to take a personal look at those games as that is not an issue I have ever seen myself
