Sega Saturn Mod Chip Notes

The info on this page is just here for historical purposes now.  A new Saturn Modchip exists, is in production AND it works with ALL SATURNS – 20 and 21 pin models and all their different model drives.

Just buy a Phantom Universal Mod-Chip – check out these posts by Zer0-2k11 and (of course) Bad_Ad84.  The next time I get a Saturn – this is what I’ll be installing.

The other option is forgoing using CDs altogether and instead using the RHEA or PHOEBE, or keeping an eye out for this recent addition.

If you want a pain free way of playing CDr discs on your Saturn, then I think the best solution is to install a modchip, the alternatives are hunting down some old/rare’ish carts, doing disc swaps, messing around with the lid switch etc.  I guess once you get used to a method, you don’t mind it, I’m just used to having the modchip fitted.

If your Saturn has a CD drive that attaches to the motherboard with a 21 pin cable, then you’re in luck, there’s a few shops selling a suitable modchip and they usually provide excellent online guides for installing it.  Have a look at and Racketboy for example.

If you have a CD drive that attaches using a 20 pin cable (Model 1 Saturns with oval buttons, and some very early Model 2’s I think), then it’s a lot more difficult.  I haven’t seen a suitable chip for sale for years.  You can mod your modchip though!

Here’s the best guide I’ve seen for it, along with some more info.  Here’s a copy of the original guide should Sega Style ever vanish

Since this post was created, there is now a Universal Saturn Modchip available!  Another is available via ASSEMBler
