You can buy a new Sega Mega Drive to Philips CD-i adapter (Sega2CDi) right here right now (probably the final stock)

CD-i member Lauraiss has just started to sell the final batch of Sega2CDi (Sega mega Drive to Philips CD-i) adapter which allows you to connect a Sega Mega Drive gamepad (including wireless versions by 8bitdo) to your Philips CD-i controller port. Lauraiss: "This is an adapter, that allows to use SEGA megadrive/genesis and all other compatible 3 and 6 button controllers (3rd party, master system etc.) on Philips CD-I player. Tested on my Philips CD-I 450 but as far as I know, all CD-I players share same controllers. It is carefully built by myself, using high quality materials and my own code. Also tested by me with several games. Folks, this is most probably the last stock of Geness_to_CDI adapters. Right now I’m in a mood for rant, but I’ll keep that for my cat. Anyway, get those while they are here. I will be selling 7 of these, since I want 3 to keep myself. What a nightmare it is to solder 10 adapters in a night, it’s about 14h process."

About the device: Although, this device is hand made by me, it is made with care and should withstand quite ruff conditions. It should serve You long and reliable, if you follow these few suggestions: 

Trust me, I’ve tried, now mine have marks of knife, where I cut this outer layer shorter. Otherwise, I do not see much that could fail in it. It does not matter what controller you plug into DE-9 (aka DB-9) socket, nothing can break adapter unless it has its own external power source and voltage does not exceed 6V. How to use: I’ve tried different controllers that I plug in it and they all worked, but this manual will cover most probable scenario – 3 and 6 button SEGA 16bit console gamepad. Philips (or any other manufacturer) made their CD-I players with three buttons in mind, 1st, 2nd and 3rd, and a directional pad or mouse. So what your adapter does is mimic all these functions, or one might say, translate SEGA controllers input to language that CD-I understands.

Now using 6 button SEGA controllers is a bit tricky, because of included extra functionality, but you’ll get a hang of it. Directional pad and buttons A, B, C and Start, work exactly the same as for 3 button SEGA controller buttons, therefore A, B and C mimics 1st, 2nd and 3rd button on a CD-I controller and D-Pad does what it should. Start button also duplicates C button. 

 

 I only have CD-I presentation controller and this is why, this project started. So speed 4 is a reference speed, but it is a little too fast for my liking, so I set 3rd as a default speed. How is this useful, you ask? This is for the games that controls via on-screen cursor, for example „Merlin’s Apprentice” (not to be confused with great 2d platformer „The Apprentice”) and „Monthy Python’s” games. Some games have their cursor move to slow or too fast for my liking. Of course, you can ignore these extra features at all and have fun playing games the way they were meant to be played. As for myself, I use them not so often.

Please note, that adapter has no internal power source so all your settings will be defaulted as soon as console is switched off or adapter unplugged from it. 

I’ve found my adapter not responding once, and reason was that adapter was not plugged in properly. 

I know that this adapter is compatible with many different controllers, even with my own DS4toSEGA adapter, still I am not able to test everything. If you find some incompatibilities please let me know by sending me and email, that is lauraiss@inbox.lv, or comment in my home page http://www.lauraiss.wordpress.com . Any feedback will be appreciated. 

Thank you and enjoy your games! [Thanks, Lauraiss]
