Hacking Would Haxchi be possible with other VC's (Wii, GBA, N64 etc.)?

It's an interesting question

N64 VC has contenthax, so yes, haxchi would be possible (but with another name since haxchi's name is based on the DS VC name iirc)

Yes and no...

Haxchi was develop under contenthax concept and there's a version for N64 VC, but not public released.

You can try yourself to develop something.

Interesting, I didn't know about that.
According to that the vulnerability was found but never exploited, so it's far from being in a useful state, and might not even be possible to exploit for our purposes. It's certainly far less flexible than the JIT-capable DS VC.

Certainly not Wii VC, because it runs in a sandboxed Wii mode and the part that runs in Wii U mode (the fw.img) isn't modifiable with contenthax as it's stored in the code directory. That is assuming the fw.img even runs in Wii U mode which it might not, I'm not entirely sure.
With others it will be hit and miss. DS VC is a good target because of the JIT capability meaning we can basically execute almost anything we want without crafting a ROP chain or even finding a vulnerability (AFAIK), all that's needed is to create ARM assembly code that will be translated into the right PPC assembly that we want by the emulator.
The other VC emulators don't seem to use JIT, so they would rely on the more conventional method of exploiting vulnerabilities and using ROP chains to gain code execution, which may not be possible for all of them.
At least that's how I understood it, with my limited knowledge of the Wii U inner workings.
