Are you sure you want to add a 60MHz :drool: switch? I would say 60 Hz are enough for your TV... ;) Here are some links: http://www.mameworld.net/pc2jamma/satmod1.html http://users.skynet.be/DuNe/Console/saturn...urn-model2.html http://www.saturn.v21hosting.co.uk/switch.htm...

You don`t need a special circuit or resistor to switch the jumpers, but if you want one switch to change the region (instead of three switches, one for every jumper) you need a small circuit with a hex inverter. You can solder a switch to every jumper and that`s it. I can`t open the picture...

Thanks for your help! :) I will try it, when I have a little time for that...

Found that: http://www.retrodev.com/transfer.html So, is it possible to stream roms from PC to Mega Drive / Sega CD? Can`t believe that it will work... :blink:

I want a US version of a Sega CD System, but I only have two PAL systems. Now I`m thinking about to change the bios chip of one PAL system. I have a US bios file which I found on a webpage. Would it be possible to burn the bios on a chip and solder it into the Sega CD instead of the PAL...

I would like to buy a multibios, too. Where can we buy it? :drool: Or can anyone give me a instruction how I can write my own multibios? :huh The SCDConvert programm "isn`t working", because my Sega CD system does not work when I plug in my 60Hz modded Mega Drive. And I wanna play the...

Jandaman's Action Replay Plus Thanks for the informations! I did the mod to my Action Replay 4M+, too!!! BIOS on my card is v2.01. All games are working now!

Where can I download the multi-bios? I will try the mod... :)

Cut the pin 79 of the VDP1 chip with a cutter from the mainboard.(mainboard top). Then pull it a little bit up with a small needle and solder a little wire to this pin. Fix the wire with tape on the VDP1 chip and solder it to a switch, so that you can switch the wire to pin 79 between ground...

Thanks for your help! :) I bought another Saturn, soldered a little and now it works... :rockin: Now I have a fully modded Saturn with Mod Chip, 50/60Hz Switch and Multi Region Mod! :cheers Never had so much trouble with a modchip before... :damn:

There is a guide for a Region Mod for the NES http://www.nescenter.de/features_umbauguide.htm EDIT:Sorry didn`t see that you don`t want it that way...

For the Region Mod you have to cut some jumper connections. I didn`t know exactly which ones, but I cut all jumpers from the "System Manager and Peripheral Controler Chip"! :hehehe:

Got it to work, too. :P But I cut the legs of the chips from the saturn mainboard and soldered the wires for the switches directly on the legs of the chips - instead of cut the jumpers and solder the wires on the mainboard. This was easier for me because I didn`t have to trace the "lines" on...

Confirm that! :) I took the red wire from powersupply,too. Now the CD spins all the time, and the saturn goes to the media player screen as before, but now the CD doesn`t stop. The screen changes into black as a normal starting game, but then nothing happens. Which pin could have no...

Yes, it spins a few seconds, then it stops. I have no idea why... :rtfm

I have plugged it into the other end so that its standing up. The frontside of the mod is facing away from the cd-rom. I tried every position and tested all my soldering. Nothing than green cubes... I think there are two possibilitys. Maybe I made some mistakes and fried the chip or I did...

Thanks for your reply! Mmh, I'm pretty sure that it is soldered correctly to the 5V source. It`s the red wire from the power supply. And it`s connected to the left solder pad in the left upper corner of the backside of the chip. Any other ideas?

I tried it on a model 1 saturn and it didn`t work. The audio player appears and I can see green cubes on both sides of the screen. It`s the same with copies and original games. Always green cubes. *Aaargh!* :blink: What pin could be wrong? I used the picture from seal1 and my saturn looks...
