Sega Saturn Region Free BIOS NOOB Questions

Hello Everyone,

I have recently aquired a sega saturn and want to have a crack at replacing the BIOS with a region free BIOS, I have the MX chips and a programmer and have done dreamcast ones before but i have a few questions when it comes to the sega saturn bios.

I know there are a few models of the sega saturn, Model 1 and 2. and the Hi-Saturn and the
JVC/Victor V-Saturn.

My question is what region free bios's do i need to use for Model 1, Model 2 etc...

is this one universal for all saturns and all revisions etc...

they are all universal, only difference is startup animation etc.

 

Awesome thank you, so do you have a zip folder with the bios files?

USA v1.00a, USA v1.01a
Japan v1.00, Japan v1.01
EUR v1.00a, EUR v1.01a
Hi-Saturn v1.01, Hi-Saturn v1.02, GameNavi Hi-Saturn v1.03
V-Saturn v1.00, V-Saturn v1.01
Samsung Saturn v1.02

(I will have to try this out sometime this year - for now I am using my Pseudo Saturn Kai carts.)

 

also am i right in thinking they need byte-swapping before burning?

 

If you read the link you were given, you wouldnt be asking that - or asking me in PM for the files.

 

i did read the link and got the files....i just didn't understand what WW meant in the filename?

 

Worldwide.

 

thank you for your help

 

I thought I would reply here instead of making a new post. I have a va 0.5 and bought a region free bios. Do I need to wire anything differently or is it a exact swap. The mmmonkey page only covers the smd bios not the 40 pin boos in the older consoles.

 

Direct swap
