Micro64 v1.00.2011.11.17 Build 626 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 v1.00.2011.11.17 Build 626 Changelog:
- Optimized half cycle pixel exact VIC emulation, mainly by reordering the by-the-VIC-emulation-used variables to get better memory alignments of these.
- Extended "+audiowav" command line parameter so that "+audiowav=" is also possible now for audio WAV export.
