CCS64 is a Commodore 64 Emulator for PC .

Changes :
- FIX: Fixed a bug in the sprite-to-sprite collision-detection register.
- FIX: Fixed a bug with the ´Windows´ menu Options -> Video behaviour.
- FIX: Made the graphics-drawing routines multi-threaded, for better performance.
- FIX: Fixed a bug which caused the QuickLoad/QuickSave features to hang.
- ADD: Two new Filter options, called CRT Television and CRT Monitor, which work only with the Window 2x screen mode and not with any other non-default video settings. These new Filter options include the after-lightening effect.
- INF: CCS64 V3.7 was compiled with Visual Studio 2008, which led to an in-compatibility with Windows 98/ME, but greater compatibility with Windows 7; when previous versions were compiled with Visual Studio 2005, this had the opposite effect.

Here is a list of changes:

-[EMU] Improved speed by average 20% in all cores
-[EMU] Fixed issues with shadow/hilight mode, vertical scrolling, DMA bugs, sprite collision, aspect ratio and timing in the Genesis/Megadrive VDP
-[EMU] Cleaned up Sega Genesis / Megadrive state, reduced size of it by 600% (allowing more rewind per megabyte)
-[EMU] Fixed bug in 6button controller that stopped it working in some Genesis/Megadrive games [Sasha]
-[EMU] Fixed a few Genesis/Megadrive memory map issues [Eke]
-[EMU] Improved YM2612/Z80/VDP timing in Genesis/Megadrive (along with other fixes 98+% of all Genesis games work very good now)
-[EMU] Fixed slowdown bug when games read input ports too much (Legend of Galahad, Kawasaki, Aleste) [Sasha]
-[EMU] Fixed numerous bugs in YM2612 core (fixes Gynoug, Beavis and Butthead, Streets of Rage and a few other games with strange glitches) [Eke,Sasha]
-[EMU] Cleaned up Sega Master System, Game Gear, Sega-E and Nintendo states
-[EMU] Added "full display" option to Game Gear. Shows the full Game Gear frame which often has valid screen data.
-[EMU] Added native sampling to YM2413 FM chip (SMS)
-[EMU] Improved efficiency, accuracy and general cleanliness of SMSVDP (SMS, GG, SEGAE)
-[EMU] Improved NES sound filtering, now sample internally at over 240000Hz and then down sample for increased quality.
-[EMU] Fixed bug in Z80 LD R, A instruction
-[EMU] Implemented Z80 IM2 support
-[EMU] Added some config options to set frequency cutoffs and mixing levels of certain audio devices

-[SOUND] Added new high quality resampling engine with different settings for speed. Every sound chip now uses it.
-[SOUND] Added 3 band equalizer (using Linkwitz Riley 4th order) , low (bass boost), medium and high frequencies can now be amplified separately
-[SOUND] Added filtering option which is designed to simulate capacitors/resistors/etc that sound on real machines was filtered through

-[CORE] Added reset button which forces hard reset
-[CORE] Added automatic save states to all systems. Simply leave a game and resume it at any time at same point you left. Can also do manual saves
-[CORE] Added SSE2 optimizations throughout (now a requirement)
-[CORE] Added memory alignment functions for better multithreading performance of video/audio buffers
-[CORE] Upgraded to boost 1.42
-[CORE] Fixed bug that didn't recognize .SMD files for Genesis/Megadrive conversion [lolcano118]
-[GUI] Fixed bug that wasn't translating some keys correctly like the underscore [Pixel_Crusher, Entrax]
-[GUI] Added new slider control for volume/bass/etc adjustment

Aeon is a DOS emulator for windows. Here is what's new :

* Fixed memory leak when launching more than one program without restarting Aeon in between
* Minor performance improvements
* Lots of DOS process management fixes
* Command interpreter is now less of a kludge and uses interrupt-driven I/O like everything else
* Added configuration support and configuration editor – not complete yet
* Can now change drive mountings while emulator is running (with sometimes disastrous results – use only for disk swapping!)
* Integer divide-by-zero CPU exceptions now handled more efficiently
* Added command prompt change current drive command
* Added some primitive MSCDEX support – a _few_ CD-based programs may work now
* Fixed bug in LMSW instruction
* Fixed bug in DOS get file attributes function
* Added support for launching DOS programs/configuration files via command line
* Fixed intermittent crashing due to bug in mouse driver callback
* Fixed some issues with how Aeon handles invalid MS-DOS file names
* Lots of internal code cleanup and refactoring

Changes :
I suppose I should start calling these nightlies, heh. blargg went ahead and verified every last possible edge case with regards to the S-CPU MUL / DIV registers. It uncovered a few errors in my implementation, which have since been corrected. The design used now should be a direct reflection of the hardware implementation: no actual multiplication, no actual division, and no variable-length bit-shifting.

We also spent about eight hours straight hammering away at the S-SMP test register. We have a partial understanding of TEST.d3 and TEST.d0, and a complete understanding of the other six bits. All of this has been implemented as well.

Lastly, snesreader gets a tiny update to fix Test Drive II, which broke due to a slight regression when porting the mapping code to XML.

Beta 17:

- right mouse button popup menu disk changes fixed, added "copy from dfx:" options
- possible D3D performance improvement when updating screen only partially
- CE mode crash fix when display updating is disabled (Scroll Lock)
- CDTV: return CD error status immediately when program attempts to play non-existing cd audio track instead of relying on CD backends to notice the error (Psycho Killer CDTV)
- do not show inserted CD32/CDTV quickstart CD image in floppy drives panel (currently cd image is quickstart-only)
- added "save screenshot to clipboard" input event (previously only save to file was possible)
- some statefiles didn't select correct refresh rate (PAL/NTSC) when restored
- added small delay to RTE instruction in 68020 CE mode because MOVE.W #x,INTREQ; RTE; currently executes too quickly, faster than emulated IPL lines change state causing interrupt to start again after RTE (another case of improving one part of emulation breaking lots of programs because not directly related part is not yet exact enough..)

Latest reports from our beta testers. Seems that another game Kazook is now almost playable (few graphics bugs). Few more games reported to have better behaviour now , more WIP updates will come soon. (P.S don't you love the fps?)
