Hallo Nick,

I'm sorry but I don't ubderstand some things.

A core-emulator just emulates the 6502, not the C64, yes?
"in the hope of getting it be the 6510" This I don't understand at all, I 
am afraid that this is an English idiom I'm not familiar with.

Here I am confused as well. Talking about mirroring regarding the SCPU your 
cor-emulator emulates a SCPU?

I'm sorry for any inconvenience but if you rephrase it you would do me a 
big favour. I am always very interested in hardware things.
