Ask general Genesis/MD/Sega CD/32X questions here (for new members)

Sorry if I was being perceived as rude. Let's just call it "passionate". :D

You know, I think we might have simply been calling the same thing from different perspectives. I look at it this way: when sticking a CD into a tray, the label is always facing up, so I call it the top. The part without the label is facing down, so I call it the bottom. The laser beam is UNDER the CD and shining against what I call the bottom, so for the laser to read data, the reflective layer must be at least FACING the bottom of the disc. It's closer to the top on modern manufacturing techniques, but it's not the top. I think you're calling it the top because the layer is mechanically closer to the top due to the thick clear plastic that covers the bottom. I think of that plastic like a layer of paint: you wouldn't call the paint on a hull of a ship the bottom - the hull is, no matter how thick the paint is. So I guess it's just a matter of perspective.

Cant seem to get my 32x hookups to work.

Somehow im missing the sync. i see the menu and stuff, but its all wavy, yall know how a unsynced screen lookes like.

i used these:

to make the megadrive to 32x coord.

i wired Green, blue, red, sync and composite
skipped ground, sound left, sound right, +5VDC and mono audio.

then i made a 32x to scart following this guide. except that i got the audio from the stereo headphone jack.

I've fiddled with it for a while now, running out of ideas :<

I'm no expert, but when I wired my Gen1 video port to my 32Xin port on my Neptune clone, I used those diagrams and I connected all the wires that I could. I would try adding the ground in and see if that makes a difference. Unless you have it wired in somewhere else.

hmm, guess i have to try to get the ground in aswell.

The reason i skipped the ground was because the mini din plug was kinda hard to get together. so im only using the part with the pins, not the outer casing with the ground.

On more wierd thing is that i wont get the sound through the cable.

when i hook up my sorround system directly to the genesis i hear the sound from doom32x. but when i plug the stereoplug in the md1, i wont hear doom.
But if i plug my ipod on the cable i've made, the music plays on the tv.

HMm, a picture say more then a thousand words:

eDIT: ohh, i didnt get the ipod audio in the tv, plugged in the wrong cable :P so nvm that picture. Guess theres something wrong with my sound wiring aswell.

Here's SCART diagram for the MD2 that's easier to follow:

Hey, my Model 1 Genesis' Reset button and Volume knob doesn't work anymore. Is there any way I can fix these problems?

EDIT: NVM, the Volume works, for some reason I thought it worked all around and not just with headphones. The reset button is broken though.

Im going crazy over here. Starting to think that maybe the 32x is borken. I've mailed the guy who sold it and asked, hopes he answers truthfully.

I've wired everything but +5VDC and the sound. I shouldnt wire the +5v right? And the sound shouldnt have anything to do with the frekking sync.

Whohoo! Progress! Now im have sync, kinda.

The menus and stuff are in sync, but the game itself isnt.

My guess is that the SMD -> 32X cord is working, but theres something wrong with the 32X -> cord.

I followed the pinout fror the SMD->32X cable in this guide:

Hiya,

Got a problem with a multi mega I just bought-

Pressing the power button normally won't turn the machine on, I have to press it with just the right amount of force for it to turn on, and if the machine is moved *at all*(even at times when the contoller cable swings a bit), this can turn it off, which is a problem.

Anyone know if this is something that can easily be fixed? can I wedge the button out with a screwdriver or somesuch and place it back?

Cheers.

Hi,

I recently bought a JAP MegaCD 2 from Play-Asia, pre-owned. It's fine outside, and almost complete (missing two small plates and the mixing audio cable :().

I have a PAL Modified Megadrive 1 (with Region and Hz selectors). I hooked it to the MegaCD, the MegaCD boots fine and i see the logo (2.0 bios by the way) and hear the music (i'm using a RGB cable with an additional cable that goes to the headphones entry for stereo sound). At the bottom there's a japanese message, which i don't understand at all (maybe it's "Press Start Button", not sure). I then press any button (A, B, C or Start) and the message changes, but that's all. No audio cd player, nothing. And i tried with an audio cd (i don't have any megacd game at the moment). Of course, i tried with every region/hz combination possible, but the result it's the same (only noticed the bars appears when i use 50hz, but that's normal).

So now i'll ask my questions, in hopes someone can help me here: Do i need a JAP Megadrive 1 to get the JAP MegaCD 2 working? Shouldn't the region switch help with that? It's my JAP MegaCD 2 broken or something? Maybe with the Megacart i ordered (i hope it arrives soon) could work...?

I think that's it :/

No, you do not need JP MD to get JP MCD working.... Megacart will allow you to play Eur and US games on your JP MCD though...

Are you using correct AC brick or something else ? Too weak brick can cause such issues... my MCD will not recognize any CD with wrong AC brick...

Soldering is needed in all cases if you want permanent fix... this sounds like a busted switch, and only way out is replacement switch or making things so that the unit is switched on all the time.

Thanks for answering me TmEE.

I've used an UK power supply, 9V, 1.2A, center negative (which i used for a PAL Megadrive), connected to a stepdown transformer. I have the original JAP MegaCD 2 power supply, but the plugs were a little short and it didn't connect to well to the stepdown transformer, so i thought changing it for the UK power supply, which is 220v but it seems to work (well it powers on).
Do you think that's the cause? What happens to you exactly if you don't use the correct power supply? Does your MegaCD shows the same symptoms as mine? (just to compare)

Thanks again.

Everything seems to work, except when you put a CD in, it will say no CD... things seem to spin up and you'd expect things to work. MD1 AC brick should be good enough for MCD though.... in fact, I have my MD2 modded so that my MCD2 gets powered through MD2 (so only 1 AC brick is needed), only side effect is some humm in sound when the CD spins up or there's some seeking (not really enough power), but other than that it works.

Also, have you tried to clean the contacts of the MCD connector ? it can help... also cleaning the lens can make a difference aswell. Can you hear CD spinning and laser moving in the system when its powered and there's a CD in it ?

Ok, i tried with the original JAP power supply, and cleaned the expansion port, and it seems to works very nice now. This is weird and great, but oh well.

Now a little problem. I tried first with an original audio cd, and works great. I also looked at the ram and saw some data there (in jap of course), so i formated it. Then i burned Sonic Megamix 4.0b Jap version on a Verbatim cd, at 1x, with ImgBurn, and tried to run it on my Mega CD 2. It runs, and went well till i tried to start a new game (with Save option enabled). Then a black screen and nothing (but i think it was reading the cd). It was like that for 10 minutes or so, so i powered off the unit, and powered it on again. There was the sega copyright thing, and a license with a purple background, with white text and "Now Loading..." at the bottom. But it didn't get past there, also the title seems to be incomplete (corrupt?), when it wasn't before. Sometimes shows "Sonic the Hedgehog Mega", sometimes "Sonic the Hedgehog Megam", and it was complete at one time i think, but never loaded fine and got to the title screen like the first time.

I've readed that Mega CD can be picky sometimes at reading cds. Sometimes because of a specific game, sometimes because the burning process with backups (burning speed, cd manufacturer, burning program, etc). I need to try more jap games, because i'm not sure yet if they'll play fine after trying Sonic Megamix. And i can't be sure just because the audio cd played fine...

I'll let you now soon, when i try tomorrow again. But for now, please tell me what you (or whoever read this) think about it.

That's all, and thanks again for your help/time TmEE.

PS. I almost forgot. I tried to play the audio cd after the failure with Sonic Megamix, and it played fine again like before.
