Sorry, I dont think this has the character of respectfully asking. Even though a petition byself could be used to do it. YMMV

The big question is whether it really makes sense to ask. There are several emulation programmers on this list. It would really make much much more sense to ask _them_ to integrate their work into VICE.

Boy, doing a CPU emulation byself is really easy. But building a framework for cycle/rasterline- exact emulation is not. And thats what the vice guys already have done. Next to it there are quite a bit of similarities between VIC and TED,
so probably a lot of the VIC emulation code could be used as well.

But indeed - emulating some of the writable TED registers might give quite a bit of a headache ($FF1D, $FF1E, $FF1F .. ). But luckily not that many programs write to them.
