Aimed to become the fastest C64 Emulator.

It's powered by a 6510-to-X86 Dynarec Engine.

1. introduction

---------------

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.

2. minimum specs
