Micro64 1.00.2011.10.02 Build 594 is released. Micro64 is a freeware commodore c64 emulator. Currently micro64 has two different VIC II emulation modes: cycle exact (default, works fine) and half-cycle exact (next-gen, rudimentary implementation – currently damn slow).

Micro64 1.00.2011.10.02 Build 594 Changelog:
- Micro-optimized and rewrote some big parts of the half cycle VIC2 emulation, so that it uses now less branches and more DFA-like Lookup-State-Tables to reduce host-CPU-branch-predictions.
