Yes, there is a lot of backwards compatibility with each new instruction set but the differnces between a PowerPC 750CE and a Power7 CPU means you can't just drop code from the former on the latter and expect it to run.

i read that the nintendo-ppcs offered additional instructions but these can easily be added again.
can you please tell me what the difference exactly is in the isa of the wii-cpu and the power7? which would have to be emulated? looking at the above mentioned wikipedia-article the isa gets *extended* with every new generation - not changed, not exchanged.

Go through this.

Then read through these.

It's not a simple as you are thinking it is.

ok, read it. now you tell me why it is not simple if the isa of broadcam is mostly a subset of power7 which can be altered to nintendo's needs easily. really, you throw a 600-paper-doc at me without having it read by yourself? this is ridiculous.
i pleased you once before: where are the major-differences? where are the complications? linking to big documents to shut someone's mouth is not a good style...
