Kega Fusion is a Genesis/Sega CD/32X/Master System & Game Gear emulator for Windows.

"You may have noticed the big jump in the version number? Somebody commented that they didn't bother trying Fusion, because of the low version number... Well, since there has been Kega, Lazarus, and now Fusion, that makes this Kega 3.0, right?"

• Fixed problem with 32X PWM when changing SampleRate.
   
  
• Added Genesis Border Colour Emulation, and option to disable it.
   
  
• Small fix to 6 button pad code (Double Switch - thanks TascoDeluxe).
   
  
• Much improved Sega Mouse support.
   
  
• Config Dialog now remembers what page you were on
   
  
• Removed ISO/BIN reading for SegaCD - this is now handled by the BIN/CUE engine. You won't notice any difference, but trust me, its better
   
  
• Fixed bug in BIN/CUE engine when multiple files were used.
   
  
• Added MP3 support to the BIN/CUE engine. Yes, this means that Fusion now supports ISO/MP3. Fusion uses the Windows Codec and therefore contains no patented algorithms. Too many people asked for this feature, so although I didn't really want it, it's now there.
   
  
• VSync now works in Windowed mode. Be aware that this can severely slow down the emulator, especially if your monitor is not set to a multiple of 50hz or 60hz, depending on the region of the game you are playing.
   
  
• Made improvements to both Standard and Alternate Timing modes.
   
  
• Added Pro Action Replay support for the Genesis.
   
  
• Added GameGenie and Pro Action Replay support for the GameGear and Master System.
   
  
• Added CodeFinder for Pro Action Replay.
   
  
• Fusion should now be compatible with WinXP Visual Styles.
   
  
• Added "Fast Forward" mode. Probably doesn't work if VSync is enabled...
   
  
• Various small optimisations.
   
  
• Fixed a couple of minor issues affecting the SegaCD BIOS CD Player only.
   
  
• When Fixed Aspect is disabled, Filtering is enabled, and you are running an NTSC (USA/JAP) game, the screen will now be slightly stretched. This works for all consoles. Stretching does not happen for PAL games, because PAL TVs show more lines than NTSC TVs, and because some PAL games use the extra portion of the screen (Virtua Fighter 32X, for example). And no, it doesn't completely remove the Master System border. That would look very, very wrong.
   
  
• Now supports up to 24 Render Plugins. This should now be way more than enough.
   
  
• Switched around the naming of the various Scanline modes. People like it better this way.
   
  
• Fusion will now start in fullscreen mode if it was exited from that mode. Other stuff that I've forgotten..

WinFellow is an Amiga emulator for Windows.

• 1. New sprite handler
   
  
• The emulation core has been upgraded with a new sprite handler. The missing sprites within SuperFrog, Alien Breed, Hybris & Shadow of the Beast are now visible. Next to this, a sprite priority bug has been fixed. This fixes graphical glitches within Bart vs. the Space Mutants and Cannon Fodder. The sprite emulation is still far from perfect and improvements can be expected within future releases.
   
  2. Conversion of assembly code to C code
   
  
• The emulation core of Fellow was mainly written in assembly code. This made it hard to fix bugs and hard to add features. It also makes WinFellow dependent on x86 compatible CPU's. We started conversion of all assembly code. Already more then 45% of this code has been converted to C code. Almost all chipset related assembly has been converted and mainly the 68k (cpu) emulation needs to be done. If correctly done, the end user should not see any difference, it is a future investement into Fellow (the emulation core of WinFellow). It will make Fellow portable to other platforms (PowerPC G5 (Apple), Samsung ARM Processor (HP iPAQ) and the Intel PXA270 processor (PalmOne Zire 72)) and make it easier to add features and fix bugs.
   
  3. User friendly configuration file handling
   
  
• The loading and saving of configuration files is now left to the user, instead of WinFellow writting every made change directly to disk.

DSemu is a GBA emulator & soon to be DS emulator for Windows.

"I now have seperate DS mmu and gpu source files. The DS mmu copies the ROM over to 02004000 as the hardware seems to, and the gpu does nothing different (not even the resolutions) yet. Even so, I now have gba.dll AND ds.dll, and that is good news.

 

Good enough to warrant a versioning up, I think. I've hit beta E, so y'all can celebrate this fact by downloading it and trying it out. If you want to load a DS rom, the only way to change DLLs right now is to modify LoadDS in the INI file. You can probably work out what values the variable can take.

 

And before I get all sorts of complaints, I know it'll crash. I've just put the compilation framework down, that's all.."

MESS is a emulator which emulates a large variety of different systems.

• System Driver Changes:
   
  
• [APPLE2] Changed joystick default key mapping so not conflict with keyboard mappings.  [Nate Woods]
   
  
• [APPLE2] Fixed a regression that could cause the screen to flash under certain situations.  (bug #634) [Nate Woods]
   
  
• [APPLE2] Fixed a regression that prevented certain Apple II models from booting introduced in MESS 0.91.  (bug #635) [Nate Woods]
   
  
• [APPLE2] Complete rewrite of Apple II banking.  [Nate Woods]
   
  
• [APPLE2] Driver will now accept.dsk images with up to eight extraneous bytes.  (bug #638) [Nate Woods]
   
  
• [COCO] Added support for The Rat graphics mouse.  (bug #639) [Tim Lindner]
   
  
• [PC200] Fixed driver to successfully boot.  [John Elliott]
   
  User Interface Changes:
   
  
• [WINDOWS] Toggling the menu bar will no longer change the window size.  [Nate Woods]
   
  Imgtool Changes:
   
  
• Created a new Apple ProDOS Imgtool driver (only reading supported for now.)  [Nate Woods]
