Micro64 v1.00.2011.11.19 Build 631 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 v1.00.2011.11.19 Build 631 Changelog:
- Replaced old whole-cycle-exact VIC emulation with a new 4-pixelblockwise-exact VIC emulation, and renamed the halfexact VIC emulation to 1-singlepixelwise-exact emulation
- Fixed a bug in the PRG2D64 routine
