'''Kega Fusion''' (also known simply as Fusion, and initially named Kega II) is a [[Sega Mega Drive/Genesis]] [[emulator]] by Steve Snake and the third and final emulator of the [[Kega|Kega-series]]. It also emulates the [[Mega-CD]], [[Sega 32X]], [[Sega Game Gear]], [[Sega Master System]], [[SG-1000]] and [[SC-3000]]. It runs only on Microsoft Windows Systems, Mac OS X and Linux. Kega Fusion is based on the earlier (and now discontinued) [[Kega (emulator)|Kega]] and its successor [[Kega Lazarus]]. Previous emulators by Steve were [[KGen98]], [[KGen]] (both DOS) and a Windows conversion used in SEGA's [[Sega Smash Pack (PC)|Sega Smash Pack]].

'''Kega Fusion''', also shortened as '''Fusion''' and initially named '''Kega II''', is a multi-system emulator for Windows, Linux and Mac OS X developed by Steve Snake. It is the follow-up to [[Kega Lazarus]], and is the last in Steve Snake's Sega emulators after [[KGen]], [[KGen98]], [[Kega]] and Lazarus.

==History==
+
The first few versions of Fusion were numbered 0.1 followed by a letter. This system was dropped due to people's reluctance to use lower-numbered versions of any program, and Steve Snake decided to jump straight to version 3.0. After version 3.2 the emulator was no longer referred to as a "beta" for the same reason.
−
Previously, Kega Fusion used version number 0.1 with a letter and beta suffix, with the last 0.1 revision 0.1e. The version change from Kega Fusion 0.1e beta to Kega Fusion 3.0 Beta is not the unimaginable leap this would indicate. The developer, Steve Snake said that the low version number made some people shy away; sub 1.0 version software is known (though often incorrectly) to be incomplete and unstable (most freeware and open source programs are indefinitely in a beta like state since there is no need to go gold). While this was not the case, Steve dropped the 0.1 version numbering in favor of starting at version number 3.0. The logic in this version number is that Kega Fusion is actually the third major revision of the Kega heritage, in the order of Kega, Kega Lazarus and Kega Fusion. The beta moniker was dropped after version 3.2, because yet again, someone complained about not wanting to use "incomplete" software.

Unlike most [[Comparison of Sega Mega Drive emulators|Mega Drive emulators]] of the time, Kega Fusion puts an extremely high importance on accuracy as opposed to speed or other features (such as netplay, movie recording, or many other features found in [[emulator]]s like [[Gens]]). However, Fusion is highly optimized and runs very efficiently. On a Pentium III class or a similar microprocessor, Kega Fusion runs at 60 frames per second with [[Sega Genesis]] [[ROM]]s, though with the popular [[2xSaI]] graphics filter plugin the processing power needed to achieve 60 frames per second is much higher (it can also be noted that emulating [[Sega 32X]] ROMs at full speed, an 850 MHz or faster microprocessor is strongly recommended). The emphasis on accuracy shows in the Yamaha [[YM2612]] coding, which is reported by Steve Snake to be almost perfect (indeed, there are many games where sound is buggy or wrong in any Mega Drive emulator except for Kega Fusion such as the Title Screen Theme for [[Sonic 3D Blast]] and [[Sonic & Knuckles]]). Compatibility is very high with Kega Fusion, even on the infamous [[Sega 32X]], which has many games that most if not all emulators cannot handle. Since the [[Sega 32X]] [[BIOS]]s have been more thoroughly reverse engineered than the BIOSs for the [[Mega-CD]], as of version 3.3 Kega Fusion does not require a Sega 32X BIOS (though you can still use an external BIOS). Kega Fusion can emulate most (if not all) [[Sega]] home video game consoles released before the [[Sega Saturn]] (though there is some cryptic indication by Steve Snake that Saturn emulation could be possible in the future).

Along with being able to emulate most Sega home console systems Kega Fusion also supports logging to a WAV file or the successor to [[GYM]] format, [[VGM]]. VGM is much like GYM in terms of how it's created but widely superior in its accuracy to YM2612 synthesis, compression (in the VGZ format) and looping. It also has support for the [[YM2413]], a synthesizer found on the [[Sega Mark III]] (the Japanese equivalent of the Master System), which the GYM format does not. As of version 3.5, Kega Fusion supports multiplayer over the internet or LAN. While multiplayer support is still in its preliminary stages, Kega Fusion 3.51 has made multiplayer more stable. Kega Fusion 3.6 currently supports AVI movie logging in the form of a "Video 1 lossless codec."

Even though Kega Fusion is being developed separately from Gens, the development teams are more cooperative than antagonistic towards each other. The differences between Kega Fusion and Gens appeal to different audiences, with Kega Fusion having a more hardcore audience mainly because Kega Fusion is not as well known among new and/or novice emulation fans as Gens even though it is much more accurate.

Kega Fusion, also shortened as Fusion and initially named Kega II, is a multi-system emulator for Windows, Linux and Mac OS X developed by Steve Snake. It is the follow-up to Kega Lazarus, and is the last in Steve Snake's Sega emulators after KGen, KGen98, Kega and Lazarus.

The first few versions of Fusion were numbered 0.1 followed by a letter. This system was dropped due to people's reluctance to use lower-numbered versions of any program, and Steve Snake decided to jump straight to version 3.0. After version 3.2 the emulator was no longer referred to as a "beta" for the same reason.

Emulation

Unlike most Mega Drive emulators of the time, Kega Fusion puts an extremely high importance on accuracy as opposed to speed or other features (such as netplay, movie recording, or many other features found in emulators like Gens). However, Fusion is highly optimized and runs very efficiently. On a Pentium III class or a similar microprocessor, Kega Fusion runs at 60 frames per second with Sega Mega Drive ROMs, though with the popular 2xSaI graphics filter plugin the processing power needed to achieve 60 frames per second is much higher (it can also be noted that emulating Sega 32X ROMs at full speed, an 850 MHz or faster microprocessor is strongly recommended). The emphasis on accuracy shows in the Yamaha YM2612 coding, which is reported by Steve Snake to be almost perfect (indeed, there are many games where sound is buggy or wrong in any Mega Drive emulator except for Kega Fusion such as the title screen themes for Sonic 3D: Flickies' Island and Sonic & Knuckles). Compatibility is very high with Kega Fusion, even on the infamous Sega 32X, which has many games that most if not all emulators cannot handle. Since the Sega 32X BIOSs have been more thoroughly reverse engineered than the BIOSs for the Mega-CD, as of version 3.3 Kega Fusion does not require a Sega 32X BIOS (though you can still use an external BIOS). Kega Fusion can emulate most (if not all) Sega home video game consoles released before the Sega Saturn (though there is some cryptic indication by Steve Snake that Saturn emulation could be possible in the future).

Along with being able to emulate most Sega home console systems Kega Fusion also supports logging to a WAV file or the successor to GYM format, VGM. VGM is much like GYM in terms of how it's created but widely superior in its accuracy to YM2612 synthesis, compression (in the VGZ format) and looping. It also has support for the YM2413, a synthesizer found on the Sega Mark III (the Japanese equivalent of the Master System), which the GYM format does not. As of version 3.5, Kega Fusion supports multiplayer over the internet or LAN. While multiplayer support is still in its preliminary stages, Kega Fusion 3.51 has made multiplayer more stable. Kega Fusion 3.6 currently supports AVI movie logging in the form of a "Video 1 lossless codec."

Even though Kega Fusion is being developed separately from Gens, the development teams are more cooperative than antagonistic towards each other. The differences between Kega Fusion and Gens appeal to different audiences, with Kega Fusion having a more hardcore audience mainly because Kega Fusion is not as well known among new and/or novice emulation fans as Gens even though it is much more accurate.

It is highly recommended to enable "Perfect Sync" option when playing Mega-CD games, as Kega Fusion will not be able to run some of them properly with this setting disabled.

The Game Gear game Ax Battler: A Legend of Golden Axe has no sprites in version 3.64, making it unplayable. Use older versions of Kega Fusion for that game.
