Micro64 v1.00.2012.06.12 Build 684 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 v1.00.2012.06.12 Build 684 Changelog:
- Disabled NRZI flux pulse filter at GCR-emulation-based images because
these imsges are almost already clean.
- Fixed P64 writeback bug (dirty flag was not always set)
