Changing the CPU alone won't make it work. The system clock must also be
changed so that you can run at 4 MHz.

Other problems might occur though. The VIC chip won't run at 4 MHz; it'll
still have to be accessed at 1 MHz.

If you want an accelerator for the C-64, you can always check out the
Turbo Master CPU Accelerator from Schneidler (sorry if I got that wrong)
Enterprises. They use the 65C02 on their board.
