Title: Genesis/Megadrive 2 SPDIF
Post by: Qjimbo on July 03, 2005, 10:13:03 AM
Hey all,
Just modded my MD 2 to have RGB out today :D Pretty pleased with it as I have the sharpest graphics output possible :) Anyway I'm now looking into getting the best possible sound output, and my plan is to add an SPDIF connector to it as someone did with the snes here (http://alpha-ii.com/Info/snes-spdif.html). Is this possible on the Genesis/Megadrive Model 2? Or is the D/A converter inside that big scary chip ner the front? I don't have an oscelloscope handy either so I've got no idea how to find out what the sample rate is :P

Anyway comments/suggestions are very much appriciated :D

I have no info on the SPDIF thing, but interesting that you had to mod your Megadrive to use RGB out, it should have been able to do it already.

Well I don't mean anything serious, it was just my first taste of the modding world :P I merely soldered some wires onto the A/V out pins on the motherboard ^^ Oh also another thing I was worrying about with the SPDIF thing is that the SEGACD can provide 44.1Khz audio from CD directly, I'm guessing analogly... I dunno. I wish I could find a pinout for the SEGA 315-5660-02 chip.

Well, if you REALLY want to hear the best Genesis sound available you can buy a Laseractive system with the Genesis pack.  It'll set you back around $200 but it's well worth it (also plays Sega CD, MD, Mega LD, Laserdiscs and CDs)  This system supports digital optical out-thus the great Genny sound :)

Where's the fun in that? ;) And besides I'm poor :o interesting info though, I hadn't heard of that.

Well if you can't tap into an acceptable onboard source you could always add an internal Analog to Digital converter inside.  That's what I have done with my ColecoVision consoles.

Wow thats pretty neat, but I'm still gonna try and find the most direct route for the sound ^^ Once I get an MD1 that is anyway. I think the sound stuff is all hidden inside that big chip on the MD2.
