Hyper64 is a working proof-of-concept of an experimental C64 emulator implementation without resorting to a conventional CPU emulation, but instead utilizing a realtime dynamic recompilation engine which disassembles, analyzes and re-assembles the 6510 machine code as native 32-bit x86 code. It further uses a fast translation code cache.
The A, X and Y registers of the 6510 are mapped to the x86 AL, BL and CL registers and the 6510 flags are mapped via the x86 SAHF/LAHF opcodes.
Although this yields to a lot of speed emulation-wise, it also has the side-effect of not being cycle exact, but instead only being accurate on an instruction basis.
The VIC II emulation is as far as I'm sophisticated complete but also not cycle exact. The same thing applies to the CIA emulation, whose accuracy is based on a VIC II line basis. |
