Micro64 v1.00.2011.12.24 Build 658 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 v1.00.2011.12.24 Build 658Changelog:
- Fixed corrupted side border graphics bug in the second fast dynamic pixel block-wise VIC-II emulation. The problem was visible when X Scroll was changing in raster cycle 56. The primary default single-pixel-dot-clock-exact VIC-II emulation hadn't this bug and did handle this case already correct by more accurate emulation (together with pipelines and latches).
