I doesn't sound simple (even to me ;-), it only  *might* be just

I completely understand, and that's why I never wanted to take over this
part. It was *your* idea and the WIP was *your* baby. But now that you
ask, I (or somebody else) will be glad to help you there. I just want to
be quite sure that you are going to continue DD if you get a working (as
described above) kernel.

50:50 would be far more than good enough for me. :-)

You know, writing and optimizing kernels is the most fun part of
programming for the 2600 for me.

Don't worry, you will soon find out that there is still "some"
programming challenge left, even after the kernel is working. :-)

I don't think it will fit into 2K, especially because a highly optimized
kernel could require a lot of extra coding outside.

Have fun!
