Kega Fusion (also known as “Fusion” or “Kega II”) is a popular multi-system emulator for Windows OS with built-in support to faithfully reproduce home console titles from the retro 2D platforms of the 1980s and 1990s, directly on the screen of your PC desktop or laptop.

Kega Fusion for PC is a robust, feature-rich emulator designed specifically for Sega gaming consoles. Developed by Steve Snake, it stands as a testament to dedication and passion for preserving the legacy of Sega gaming. It enables users to experience a wide range of Sega consoles, including the Sega Genesis, Sega CD, Sega 32X, Sega Master System, and Game Gear, all within a single, streamlined application.

Even though the space of retro emulators today is very crowded and full of competent contenders, It has managed to distinguish itself from the competition by placing very high importance of emulation accuracy, placing other features to the wayside. This includes the refusal to accept inaccurate rendering of visuals/audio just to be able to run the game faster, or inclusion of advanced features such as movie recording, netplay or tolerance of artificial gameplay lag.

Originally released to the public in 2004 with version v0.1 (which was an offshoot of the Kega Lazarus), Kega Fusion expanded its capabilities considerably during the remainder of the decade. By the spring of 2010 and the arrival of its final version (v 3.64), this emulator gained the capability to playback games released for the following platforms: Sega Mega Drive, Mega-CD, 32X, Master System, Game Gear, SG-1000, and SC-3000.

In addition to the default sound synthesizer used for the audio reproduction of many Sega games, this emulator also has support for the YM2413 synthesizer found in the Sega Mark III. To achieve the best Mega-CD games emulation results, developers of this app highly recommend keeping the option “Perfect Sync” enabled during gameplay.

Today, years after its final version was released to the public, it remains one of the most accurate Sega Genesis emulators out there, with only a few games out of its large library unable to be played. Kega Fusion is fast, lightweight, and very accurate in rendering 2D classics, enabling anyone with at least a Pentium III processor to relive their gaming memories of the 1980s and 1990s gaming on their home PC.
