Micro64 v1.00.2011.12.15 Build 652 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 v1.00.2011.12.15 Build 652 Changelog:
- micro64 ide/debugger now temporary removed until a rewrite in the next year 2012
- Implemented a second very exact floppy emulation logic with 16 MHz clockrate with all relevant internal clock counters from a real 1541, extra for FDI and P64 disk images, so the primary old but stable and faster floppy emulation is still used for D64, X64, G64 and NIB. images.
- Added support for FDI (read&write), P64 (read&write) and NIB (readonly) disk images
- NIB support is only temporary and highly experimental, so it can be remove at any time again, because the NIB file format can change from NIBtools release to NIBtools release!
- Added "+g642p64 in.g64 out.p64", "+p642g64 in.p64 out.g64", "+g642d64 in.g64 out.d64", "+d642g64 in.d64 out.g64", "+nib2g64 in.nib out.g64", "+fdi2p64 in.fdi out.p64" and "+p642fdi in.p64 out.fdi" command line parameters.
