Sega Mega Drive/Genesis Emulators

Microsoft Sidewinder Game Pad Microsoft Sidewinder Game Pad Pro

These are the best Sega Mega Drive (and other consoles) emulators available. Each one is slightly different in what they offer but they will all get you playing your favourite classic games well.

The best way I have found to play these is with a 6 button pad specifically the Microsoft Sidewinder Gamepads as its layout is similar to the buttons used by the console. The Gamepad exists in both 15-Pin analogue and USB versions and the Gamepad Pro is USB only. You can buy these from places like Amazon but Ebay maybe an excellent place.

To download the emulators, right click the links and select Save Target As... to save the file to your hard drive. All files are zipped so you will need to extract them.

Be sure to have the latest version of DirectX (9.0c) installed on your system. You can get it from here http://www.microsoft.com/directx

Kega Fusion - 3.63

Requires Windows (Not NT) and DirectX 7

Fusion is a Mega Drive/Mega CD/32X, Master System and Game Gear emulator for Windows written by the god of Sega Programming Steve Snake.

It sports high accuracy, high speed and plenty of other options like Pro Action Replay support.

For full speed on all emulation modes you will want a processor running at 800Mhz.

Fusion is excellent since it does not require the dreaded ASPI layer. However, Kega does not have a screen shot facility but Im sure it will eventually have. I have used previous version of the emu for many years on numerous versions of Windows with no problems.

KGEN 0.4b (DOS)

This is one of the first Mega Drive / Genesis emulators. It runs in DOS and is bested used with a Vesa display driver.

This has now been outdated by the Windows versions but if you still have a PC of around 166Mhz and Windows 95/98 then this would get you full speed emulation.

Simply unzip the file to a directory and run kgen.exe

The ASPI Layer

This is a small driver that allows programs to access functions of CD ROM drives under Windows. This is mostly applicable to versions of Windows previous to XP however an APSI layer can be installed with no problems.

In the case of these emulators, the ability to load Sega CD and play their music.

Adaptec provide a download package. You can get it from http://www.adaptec.com and searching the support section for Windows ASPI Package. (v 4.71.2)

Other OS's

There does exist emulators for Apple Mac and Linux however these are not as advanced as their Windows counterparts. You will probably be able to get full Mega Drive/Genesis but not the other systems like Mega CD and 32X.
