1) Pardon my ignorance but browsing through the sources, it appears SS 
supports NewWorld ROMs, however a 4 MB PowerMac PCI ROM is needed. 
Wasn't NewWorld ROMs (MacOS 8.6+) supposed to be sufficient?

2) It appears that SS currently relies on real addressing mode. How many 
memory regions could be relocated "together"? I am thinking here about 
direct addressing for a ppc emulator in case other arches don't support 
fix mmaping to the requested regions. Sure, fallbacking to the old 
banked memory addressing could be a solution too.

Bye,
Gwenole.
