I was going to try that, before I got the ibook. Then I got the ibook and I
wanted to get my hand dirty. Nothing beats the real thing :)
But I have figured it out, I have the code working...
It are more or less (just) two things:
- mmu off,
- make sure u copy through the cache.
And of course make sure your secondary code is working as it should, then a emu
would help :).
Thanks for the reactions.
