Micro64 v1.00.2011.11.22 Build 634 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 v1.00.2011.11.22 Build 634 Changelog:
- Sprite collisions in the optional non-single-pixel-dot-clock-exact VIC emulation are pixel-exact now, like in the default single-pixel-dot-clock-exact VIC emulation.
- Optical sprite DMA side effects in the optional non-single-pixel-dot-clock-exact VIC emulation are also implemented now, like in the default single-pixel-dot-clock-exact VIC emulation.
