			ok Some chips have shorter ones than others. I haven't heard as many complaints as of late

			Did a more conclusive test, THe mod works poerfectly. I only had two problems during instalation: I think that the mod was scraping the shield, preventing it from getting to the slot, but this could've been caused by problem 2, so I use a pair of wire snips to cut it. the other problem was that the connector was to wide, so I filed it down. Mod works perfectly :thumbs-up: Just need tha soldering iron :sigh E: Got the iron, it works perfectly now :banana

			Okay, i started reading the 29 pages of this thread 6 hours ago, and ive just got to the point of adding a reply. People when you make a comment about your sega saturn on here, post your console information, and that means: Model No: MK-80200-50 "console sticker" Serial No: AD63006030 "console sticker" Made in Indonesia "console sticker" Date: If known! "not all console have this printed" Version: PAL CD Unit Information: IC501 = 6433612H 64 Pin "located on cd unit board" ENR-011 (A) EMW10589-002 "located on cd board left side" Cd Ribbon: 21 Pin Main Board Information: PC 80 SATURN MAIN VA PAL 50 "located in the middle on the ton of the main board"

			hi was wondering what do i need to do to install a modchip to a saturn in detail please. It has circular reset and power button and basic american version. thanks

			is soldering to the 32 pin chip of the saturn really a tight space where making a mistake is easy even if you have some experience in soldering.

With a 32-pin (and now the mods seem to support 64-pin cd-blocks again) american version, you can ue the method described on page 1.

With a later ones with the Sayno (or whaterever the spelling is) it gets more complex, and doesn't always work ( I think there are multimle versions of the sayno cd board)

			Just like to thank RacketBoy for the modchip (Ben, Wales)- works great Also like to add (for anyone still having trouble with sanyo barods and the 'chip) got mine to work by using the 0019 bridge, the a-b method, and by filing down the sides of the chips connector (was a VERY tight fit that prevented a good connection before that). Oh, and by following the sanyo installation instructions (by Mike G i believe thinking back... the ones linked to from racketboys page anyway) Anyway, thanks again, hope this helps edit: grammar was appalling

*sigh*

So I received my mod chip from Jandamans last night. I proceed to read variuous instructions, both from here (SX) and here.... My Saturn is a 32 pin chip, 21 pin ribbon Saturn, the Model 2 32 pin. So I slightly file down the sides of the connector on the mod chip. I solder pads A and B together. I put the ribbon cable into the mod chip, then plug the mod chip in, and then connect to the 5v on the PSU. What do I get?

This exact problem:

Code:

    Signal wire not attached (0019 bridge):

Boot up animation

Long pause (15secs) at 'Sega Saturn' screen

Two green cubes at the CD player screen

-No CD rotation

Displays "checking disc format"

I don't understand what "Signal wire not attached (0019 bridge)" means, but I prersume it means I neeed to solder the 19 bridge instead of the default 14. I get that done, and I still have the same damn symptoms.

On powerup, I get no disk spin, but I get th standard shattered logo coming together, and then a (long-ish) wait. Then the CD Player control panel comes up, and I get "checking disc format". Sometimes the disc will spin at this point, sometimes not. Neither copies or originals are read (right) at all, no audio, no game data.

I've tried pulling and reseating the ribbon cale and the mod chip numerous times. I've checked and rechecked my solders. The fact I get this particular error seems to mean the mod chip is in fact working, else I'd not get and CD spin at all, but it's obviously not working as it should. Pulling the mod chip and connecting the ribbon cable up directly of course results in a flawlessly working boot with a commercial game.

Sooo...help? The Saturn is Model #MK-80000A with a JVC CD Board, "ASSY CD UNIT SAT JVC EXL-P608", mod chip installed component side towards CD unit, since ribbon fingers face same direction.

In my experience, with that model of CD board, you actually have to solder to the 32 pin IC to get a mod to work. I don't know why...

Yeah I would have to agree, I just ran into a Saturn a week ago that did the same thing. It was a 32 pin figured it would be smooth sailing but wouldnt work. I ended up having to solder to the pin on the chip and it worked great! When all else looks correct try connecting to the pin on the IC. even if you just tape it down to do a test it will rule out a non A+B Saturn.

Ironically I had a 64 pin to mod aswell, and I got it to boot CD-Rs in one try. Strange day in the world of Saturns.

			I have a 21/32 saturn 80000A NTSC US saturn system. It has the JVC 605 cd drive. I ordered a mod from Jandaman and I was exited to try it. I tried the A+B method out of the box and nothing. It thinks everything is an audio disc. So then I tried soldering to pin 14 on my IC. That had the same results. So then I tried changing the switch to 0019 and it does the exact same thing, regaurldless of where the signal wire is soldered. The shattered glass sega logo appears with the mod installed then it goes to the audio player. The drive is active and will read the audio from all my games. When I disconnect the wire from the IC or the power the shatter logo is no longer present on boot up. I was trying to boot several pressed sega cd's such as nights and Night warriors. When I remove the mod, the system functions flawlessly with all US games. I haven't tried filing the mod down, it is difficult to insert into the motherboard. I don't think this is the problem because when it isn't seated correctly I don't get the shattering sega intro. I ran into this in testing. I have read this entire thread a couple times and it seems that this type of saturn should be easy to mod. Has anyone gotten past this problem by filing their mod? I already talked to jandaman and he offered to send me a new mod chip to try. Now I'm waiting on that and begging anyone out there for help. Do you guys think this is a dead mod or should I try a few more things? PLZ HELP
