Micro64 v1.00.2012.03.21 Build 666 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 v1.00.2012.03.21 Build 666 Changelog:
- Added enhanced settings for VIC-II sound audio leak stuff (DC offset
removal filter, additional 15 kHz noise, etc.)
- Fixed some small beauty-bugs in both VIC-II emulations
- Added optional "fixed bitsync time pattern" setting for the secondary
NRZ-pulse-based low level 1541 emulation instead using
CPU-time-eating-emulation of all the internal counters of a 1541 drive. It
is primary for computers with not so fast CPUs as small but still nice
speedup option
- Added on/off setting for OpenGL canvas texture interpolation as wished by
some peoples
- Added "HLT is jam" on/off setting, the default setting is now that it's
JAMing not more
