Yo. Still have some trouble with my homemade 32x hookups.
When i try to play Doom32, the menus are fine, but the game itself is out of sync.
Overall the screen is a bit to red and dark.
The screen flickers a bit, black horisontal lines, not much though, but every now and then theres some lines here and there.
Original 16bits games works fine, except the lines and the red thing.
I've buzzed the cords with a multimeter and everything seems fine.
Any ideas?
Have you tried putting an electrolythic cap on the sync line that goes to 32X ? I had to do it, otherwise my 32X acted up a little (though I was using my own built sync signal instead of stock sync signal). 220µF cap did the trick.... you may try having a less than 100ohm resistor in series aswell.
Dont know if i have any electrolythic capacitors, might be able to salvage one from something i have laying around.
What dya mean by that? just one less then 100ohm resistor?Quote:

Hmm, just realized that this diagram:
http://members.optusnet.com.au/evilt...cart.htm#mega2
says that there should be some caps on the RGB lines. But that can be the problem with my sync right? :S
EDIT: This is how i've hooked evertthing up

Should sync be hooked up there somewhere? Pin 5 from genesis 2?
Speaking of building these cables...
The Hyperkin rep at the Digital Press forums is interested in making a fresh batch, plus the adaptor for the model 1 Genesis. I've sent him a pin diagram I found on this forum showing how to wire up the adaptor plug. He said the minimum order his overseas company can make is 5000 but they'd be relatively cheap. He's not sure yet if he'll order them.
However, what concerns me are the round bits on each cable. If those are important components, he needs to be told exactly what they are so they can be installed.
His username on DP forums is tofu should anyone want to send him a private message concerning this.
Whats about that Diosoth?? any news? about those cables?? they are for sell now?
Hmm, think I've fried something :cry: my gen will only display black and white :(
I've tested the cables with another SMD1, and they work as they should. :cry: what have I done? :cry::cry::cry
EDIT: Phew, was just the coord that was a bit messy. so NVM :P
EDIT2: If i plug my homemade SMD1->32x Cable, and the RF cable from the 32x, it should work right? 'cause now its just black and white. I guess that theres something wrong with my SMD1->32x Cable after all. Sigh, I thought that that one was working atleast.
Tried with the 220uf cap, didnt do anything. STill get this picture:

Regular 16bit games work perfecyly though, wierd imo :?
EDIT: big fat picture replaced with resized one.
If Stantard 16bit games, can the SMD->32x cable be fucked up? Or does that mean that that one is working atleast?
I don't know a whole lot about this, but the 32x mixing cable only comes into play for 32x games, and only for the sprite (or 3D) layer of the video. (I cant remember if the added sound channels are mixed through the cable as well)
If you don't plug the cable in at all you'll still get part of the picture (usually).
In the case of DOOM, the status bar will display fine w/out the cable, but the main screen will be blank. (black)
SO it would seem you're mixing cable isn't working right.
you have bad sync there.... this means mixing cable is having some issues.

EDIT: What about the sound? Do i really have to take it from the stereo out on the md1? I've read somewhere that the audio is transfered to the 32x via some of the cartridge pins?
all 32X sound goes to MD for mixing with MD (and MCD) sound through cart port... in 32X, the sound from AV in goes straight to AV out.
He's sent the proper wiring diagrams off to his overseas factory. It'll be up to them to build it, if possible. If they can make working cables, he can order them for sale.Quote:

And I bought a RGB cable from ebay. So no more hassle with that one. THinking of buying a 32x cable aswell, its "only" $10ish. Considering the amount of time i've spent trying to do this myself, thats a bargain ;P
But I don't want to give up just yet. Feels like im close xP
I get some interference when playing 16bit games aswell, the black lines i talked about. But the coords buzz out alright (I think, im a noob). Could the lenght of the cable be the problem? CAT5 cable might not be optimal :P
Some of you guys have made neptunes. Have you had any problems like me? With the sync failing big time?
Well, Back to the garage. Gonna try a bigger resistor.

Sigh....
I decided to buy cables from ebay. Bought one MD2/32x/Nomad/smth to SCART. Works perfectly.
Bought one SMD1 to 32x cable.
Both from good rep sellers. And guess what, same freaking problem. The only comfort in this is that im not a retard. Atleast my cabling wasnt faulty. I've had them right for a long time i guess. SO, hurray for me, i can solder... :P
Guess its something wrong with the 32x. Im gonna get some isopropanol and clean every contact on the 32x, including the ribbon-cables inside.
Hope that works. If not, any other ideas?
//sincerely flax
EDIT: Just grabbing this out of the blue. Is it possible that the cart is broken? All I have is Doom32x
Well, as I know there's one cable between the 32X and the Md1 which is for the model with the text "Mega Drive PAL-G" or something like that and one cable for the model with the text "Mega Drive RGB". I don't really know but here you got two links to both of the cables.

Maybe you got the wrong cable. I have two cables for my Md1 and 32X and they both works fine with Doom.
I got the PAL-G one, and my SMD1 is also PAL-G. So that shouldn't be the problem. Theres got to be something wrong with the 32x. The seller ensured that he tested it before he shipped it, but I don't know.
It wont work with the RF-cable either, same sync problem and its all in black and white. Same with 16bit games through the 32x with RF, its in black and white.
With the Scart cable 16bit games work fine through the 32x.
Gonna take another look inside the 32x tomorrow. Anything special I should look for? Except the ribbon cables?
And btw, the metal things your supposed to put in the SMD, they aren't necessary right?
I don't think that they're necessary. I'm using them anyway. I think that I have a pair of the metal prongs over actually but I have no idea if they works on a Md2.

Is that stock? Or is it some mod of some sort?

It dosen't look like it's anything wrong with the 32X. Maybe it's worth a try with two metal prongs but I don't know how expensive/rare they are.
Put 32x together again, and guess what, doom wont play at all now :S 16bit games still work, but not doom32. what the hell....
Try clean Doom and look if there will be any other results.
Nope =(
That's strange.
Might be something that's possible to fix since the 16-bit games works fine. But if I were you, I should get my hands on another 32X-game and see if that works before trying to fix the problem.
Reseat the white ribbon cables. No? Clean those ribbon cables with rubbing alcohol. Those ribbons are problem prone.
I've cleaned them with alcohol and buzzed them with a multimeter, they are good. :|
I'm about to make my own 32X cables, is there a pinout to include any resistors or caps around anywhere??
As always, check the power supply.
Could one of the pins (like the sync pin) in the 32x itsself be damaged?
.
<3 you Zebbe! :)
I sent the cables and doom to Zebbe and they worked fine on his system. And he was willing to sell me a loose 32x unit. Got it today and it works like a charm :)
Gonna use the old one to try out the PAL/NTSC mod before I do it on this one.
One bad thing though is that I only get Mono sound with this setup. Gonna mod the cable with an additional stereo plug so no worries.
But should I put the stereo plug on the SMD1 to 32x cable or the 32x AV cable? would be easier to but it on the AV cable, but are there any technical cons if I do that?
If (read when ;)) I get a Sega CD will the above sound setup work? I've read something about the Sega CD mixing sound or something.

Are there any other guides out there? :S Don't trust gTranslate :P I haven't read it that thoroughly but if there is an English native it would be swell.
Watch out for ones that have a jacket that can yellow in the sun....thats about the only suggestion I have for them. And youll have changing the cables....I cant think of anything I hated more....removing a gas tank/propping it so fun.
mod your genesis/Mega Drive with stereo out on the console itself, that will work fine.
That's what I did.Quote:

The genesis to 32x cable used to be a model 2 SCART cable.
flaxswe: Glad to help :). Good for you it worked out :).
I would put a cable between the MD1 headphone jack and the MCD mixing port and then 2 RCA cables from the MCD to a stereo, computer speakers or anything like that. Easiest and best way to get stereo sound with MD1, as it requires no modding and separate speakers are always better than those of the TV.
