Micro64 1.00.2011.10.23 Build 617 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 1.00.2011.10.23 Build 617 Changelog:
- Added missing color pixel shift register synchronization at the WholeCycleExact->HalfCycleExact VIC-II switch routine
- Fixed switch bug between halfcycle-pixel-dot-clock-based VIC-II emulation and wholecycle-linebasedsprites VIC-II emulation
