Micro64 1.00.2011.10.03 Build 596 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 1.00.2011.10.03 Build 596 Changelog:
- Added logging of cycles (toggle by ALT+L or "+logcycles[=startafterXcycles]" command line parameter)
- Added audio wav dumping ("+audiowav" command line parameter)
- Added optional (default disabled) extended twobyte opcodes ("+extops" to enable it, $f2$85=enable cycleslogging, $f2$86=disable cycleslogging, for logging cycles at testcase test programs)
