I'm aware of the basic premise of emulation, and that IS a great analogy too mate, though not quite what I was asking. Biggup for the reply. Everyone on this site is helpful and forthcoming, which Is quite refreshing for an online forum
I guess I could've written my original post more eloquently, so as to more ask,
"What kind of perspective increase performance do need between original hardware, and emulation hardware, to compensate for the code translation, in order to be able to maintain upto spec GC performance..?"
Again, big up for the help all of ya
