Hi Ze_Ro!
It maybe possible with the use of the Super CPU for the C64!
If you never heard of it, it's a 20Mhz Card for the C64 with the possibility to add 16MB's of RAM.
it uses an 65816 (16Bit) Processor. You can also set a "Direct-Page" that's where the zeropage would be then. I do some Stuff on that SCPU thing... and it's got lot's of power...
one thing that i don't see emulated then would be the colors... as you know the c= 64 only got 16 of them...
