RE: Region Changer on JAP VA0 - megavolt85 - 28.04.2018 00:08

read option in app Bios Flasher


RE: Region Changer on JAP VA0 - dragoncity - 28.04.2018 00:18

why read bios...it's the flashrom...? o_O

So this is the bios I read with bios flasher :

backup_1998-11-27_01-03-27.bios


RE: Region Changer on JAP VA0 - megavolt85 - 28.04.2018 00:44

it's ver. 1.004 , this bios don't use region from flashrom for regional check


RE: Region Changer on JAP VA0 - dragoncity - 28.04.2018 00:46

Ok so what is the solution for change in Europe?


RE: Region Changer on JAP VA0 - megavolt85 - 28.04.2018 00:49

replace BIOS


RE: Region Changer on JAP VA0 - dragoncity - 28.04.2018 00:52

Hum... if I change bios with "freebios" like jc-bootROM-devkit-v1.031.bin ?

Or an other?

I want just change the region for Dreamshell..is it possible to have just the Bios Dreamshell and Europe?

dreamshell don't use region


RE: Region Changer on JAP VA0 - dragoncity - 28.04.2018 01:00

Ok for be sure.. I change the bios (remove SEGA) with freebios.

After the swirl is Blue ? o_O

Because I need the region Europe for best compatibility with dreamshell Smile


RE: Region Changer on JAP VA0 - megavolt85 - 28.04.2018 01:14

after change BIOS chip you can change region via Region Changer


RE: Region Changer on JAP VA0 - dragoncity - 28.04.2018 01:16

Hum.. but I need to keep this bios and piggy back dreamshell...?

or I can reflash this bios after region changer for put dreamshell?


RE: Region Changer on JAP VA0 - megavolt85 - 28.04.2018 01:29

what need? bios for boot from GD and bios with ds bootloader?


RE: Region Changer on JAP VA0 - dragoncity - 28.04.2018 01:36

Ok I explain better.

If I change the bios and after use region changer I will have Europe,right?

So after I can reflash the bios in dreamshell and keep Europe?

Or I need to have 2 bios after?


RE: Region Changer on JAP VA0 - megavolt85 - 28.04.2018 02:02

create BIOS mod -> write jc-bootROM -> remove MPR-21068 (original BIOS)


RE: Region Changer on JAP VA0 - dragoncity - 28.04.2018 18:08

In fact there is better we can directly with DS BIOS ^^

So I tested :


Change Bios with jc-bootROM > region changer > PERFECT and Blue Swirl ! Big Grin

After I tested


Change Bios with Dreamshell No-Gdrom > region changer > PERFECT and Blue Swirl ! Big Grin

And in Region Changer Europe > PAL > French Smile

So Dreamshell Bios or Jc Bios I can change region !! Smile

Thanks for your help Wink

Ps: Why with the last DS we can't boot directly on ISO_LOADER..? o_O

Need to connect pin 23 to IC302 Pin1 for VA0...

But I tested without,and work... so why? Huh


RE: Region Changer on JAP VA0 - megavolt85 - 28.04.2018 23:07

RE: Region Changer on JAP VA0 - dragoncity - 28.04.2018 23:10

I use MX29LV160CTMC,and no problem without connect pin 23 to IC302 Pin1,so it's normal? Smile


RE: Region Changer on JAP VA0 - megavolt85 - 29.04.2018 02:08

many people kill MX29LV160 on VA0 board, you were just lucky that the chip is still alive


RE: Region Changer on JAP VA0 - dragoncity - 29.04.2018 02:10

I used 10 Mx29lv160 on Va0..no problem.. o_O

I don't understand what is the problem exactly?
