Connected to a Genesis/Megadrive, it acts as a controller! When you lean backward/forward it tells the Genesis to go down/up and when you lean left/right it tells to go left/right. Two handles on each side offer two buttons each, resulting in 4 buttons : START, SELECT, A & B. The Action Chair is basically a chair mounted on a controller. It is thus possible to play all games with it, though it is more convenient to play games like After Burner II, Space Harrier II, Super Thunder Blade, Hang on, Road Rash, Super Monaco GP, etc. Thanks to **Spycal** for this picture image: /media/museum/hardware/sega_action-chair.jpg - title: DOCUMENTATION subtitle: Page 1 text: Thanks to **Spycal** for this picture image: /media/museum/hardware/sega_action-chair_doc_1.jpg - title: DOCUMENTATION subtitle: Page 2 text: Thanks to **Spycal** for this picture image: /media/museum/hardware/sega_action-chair_doc_2.jpg connectors: - title: 3 BUTTONS JOYSTICK subtitle: '' text: |- The joystick port uses a multiplexing technique based on the 74HC157 chip (high-speed cmos quad 2-line to 1-line multiplexer) built-in the controller. There are 2 inputs for each 4 outputs of the chip. The console can determine which function is read by setting the *select* signal to 0v (logic low) or +5v (logic high). **Fun fact :** Atari 2600 joysticks could be used in the Genesis joystick ports. The button of the Atari joystick was the "B" button on a Sega Genesis, and the direction buttons are fully functional. image: /media/museum/connectors/genesis_joystick.gif screenshots: - title: NEW-ZEALAND STORY subtitle: Screenshot text: '' image: /media/museum/software/sega_md_ss_new-zealand-story.gif - title: ALADDIN subtitle: 1 - Title screen text: '' image: /media/museum/software/sega_md_ss_aladdin_1.gif - title: ALADDIN subtitle: 2 - screenshot text: '' image: /media/museum/software/sega_md_ss_aladdin_2.gif - title: PGA TOUR GOLF III subtitle: 1 - Title screen text: '' image: /media/museum/software/sega_md_ss_pga-tour-golf-3_2.gif - title: PGA TOUR GOLF III subtitle: 2 - screenshot text: '' image: /media/museum/software/sega_md_ss_pga-tour-golf-3_1.gif - title: COOL SPOT subtitle: 1 - Title screen text: '' image: /media/museum/software/sega_md_ss_cool-spot.gif - title: COOL SPOT subtitle: 2 - screenshot text: '' image: /media/museum/software/sega_md_ss_cool-spot_2.gif - title: SUPER HANG ON subtitle: Screenshot text: '' image: /media/museum/software/sega_md_ss_super-hang-on_1.gif - title: SONIC, THE HEDGEHOG subtitle: 1 - Title screen text: '' image: /media/museum/software/sega_md_ss_sonic_1.gif - title: SONIC, THE HEDGEHOG subtitle: 2 - screenshot text: '' image: /media/museum/software/sega_md_ss_sonic_2.gif - title: OUT RUN subtitle: 1 - Title screen text: '' image: /media/museum/software/sega_md_ss_outrun_1.gif - title: OUT RUN subtitle: 2 - screenshot text: '' image: /media/museum/software/sega_md_ss_outrun_2.gif - title: ULTIMATE MORTAL KOMBAT 3 subtitle: 1 - Title screen text: '' image: /media/museum/software/sega_md_ss_mortal-kombat-3_1.gif - title: ULTIMATE MORTAL KOMBAT 3 subtitle: 2 - screenshot text: '' image: /media/museum/software/sega_md_ss_mortal-kombat-3_2.gif - title: FLASHBACK subtitle: 1 - Title screen text: '' image: /media/museum/software/sega_md_ss_flashback_1.gif - title: FLASHBACK subtitle: 2 - screenshot text: '' image: /media/museum/software/sega_md_ss_flashback_4.gif - title: FLASHBACK subtitle: 3 - screenshot text: '' image: /media/museum/software/sega_md_ss_flashback_3.gif - title: FLASHBACK subtitle: 4 - screenshot text: '' image: /media/museum/software/sega_md_ss_flashback_2.gif - title: GOLDEN AXE subtitle: 1 - Title screen text: '' image: /media/museum/software/sega_md_ss_golden-axe_1.gif - title: GOLDEN AXE subtitle: 2 - screenshot text: '' image: /media/museum/software/sega_md_ss_golden-axe_2.gif - title: STREET FIGHTER II PLUS subtitle: '' text: '' image: /media/museum/software/sega_md_ss_street-fighter.gif - title: SONIC 2 subtitle: 1 - Title screen text: '' image: /media/museum/software/sega_md_ss_sonic2_1.gif - title: SONIC 2 subtitle: 2 - screenshot text: '' image: /media/museum/software/sega_md_ss_sonic2_2.gif - title: SONIC 2 subtitle: 3 - screenshot text: '' image: /media/museum/software/sega_md_ss_sonic2_3.gif - title: SONIC 3 subtitle: 1 - Title screen text: '' image: /media/museum/software/sega_md_ss_sonic3_1.gif - title: SONIC 3 subtitle: 2 - screenshot text: '' image: /media/museum/software/sega_md_ss_sonic3_2.gif emulators: - title: Gens url: http://gens.consolemul.com/ platform: Windows text: Excellent Genesis emulator - title: KEGA url: http://www.eidolons-inn.net/kega/ platform: Windows text: Kega is a Sega SG1000, SC3000, Master System, Game Gear, Genesis/Megadrive and SegaCD/MegaCD emulator for Win9x/ME/2000/XP - title: Wgens url: http://emu.makii.pl/pokazpliki.php3?tematy=smd platform: Windows text: Sega Megadrive emulator links: - title: GameFAQs url: http://www.gamefaqs.com/console/genesis/ text: All sort of FAQs related to the Genesis / megadrive (games, hardware, etc.) - title: GameWinners.com url: http://www.gamewinners.com/GEN/ text: Great cheat codes archive ! - title: GAMEX.COM url: http://www.gamesx.com/avpinouts/genesisav.htm text: Genesis / Megadrive video pinouts - title: Genesis Collective url: http://www.genesiscollective.com/ text: Giant software database, full of useful info - title: IGN.COM url: http://codes.ign.com/ text: A LOT of Genesis game codes - title: Megadrive FAQ url: http://www.classicgaming.com/museum/faqs/megadfaq.shtml text: Megadrive FAQ hosted by Classicgaming.com - title: Official 32X pages from Sega! url: http://www.sega.co.jp/archive/segahard/32x/ text: Excellent.

It is similar to the Multi-Mega, being a combination of a [Mega Drive](/museum/sega-genesis/) and Mega CD, but with the added ability to function as a karaoke machine and improved sound thanks to JVC's new DSP. The system shipped with four karaoke programs and a compilation CD of four games. Two microphones can be connected to the system so users can sing along with CDs, or, thanks to a button on the machine, the CDs vocals can be muted allowing you to sing with just the music as a backing track. In 1993 the WonderMIDI package was released. This allowed users to connect a MIDI keyboard the Wondermega to create sound effects and music, and included instructional software which could help people learn to play the piano. 1993 also saw a re-release of the system, with several small changes designed to reduce cost.
