Doctor V64 Hdd/CF BIOS HOWTO.

Yes I know the format on this page is fucked for some reason, don't ask me how html code works and i'm too lazy to fix it so it will just have to look like total shit ;).




*DISCLAIMER*

USE THIS AT YOUR OWN RISK.

I CAN'T BE 100% SURE THAT IT WON'T BRICK PEOPLE'S V64'S.

If people use the new Cf/Hdd BIOS and they have an epoxy EPROM, there may be NO way to update to any other BIOS afterwards!! Of course, if anyone with a removable FLASH chip tried this BIOS, it will need re-flashing with an EPROM programmer to update it again!

ONCE YOU UPDATE TO THIS BIOS YOU CAN'T REFLASH SO YOU ARE STUCK ON THIS BIOS FOREVER!

HIGHLY EXPERIMENTAL , MAINLY RECOMMENDED FOR PEOPLE WITH 128MBIT RAM IN THEIR V64'S AS I HAVE NO IDEA HOW 256MBIT GAMES RUN WITH THIS SETUP!.


I came in contact with OzOnE_2k1 and he gave me this compilable version of his V64 Hdd BIOS that you can download at the following mirrors:

1) http://www.filedropper.com/v64hdd-working28-1-08ozone
2) http://www.megaupload.com/?d=A5EB0MGP
3) http://www.zshare.net/download/7569512673f5554b/

The following worked on my V64 upgrading from BIOS V2.02 to the new Hdd BIOS.


The rar archive has the same filename as the old archive from rapidshare found on various pages in google but it now contains more files and by clicking test.bat it will now compile a test.bin file that you burn as a file and not as a image file using DAO 9660 MODE. It is important that you rename the test.bin file to "v64_ver2.03.bin" or else the Doctor V64 will not recognize the file as a BIOS upgrade file but just as a game rom.

If you have named your BIOS file incorrectly it will look like this picture:























And if you've named it correctly it will look like this:















Boot up your cd with the BIOS file on it and press the CH button and then the "Play" button

After you have pressed the MENU button it will flash your BIOS and now you will see the new screen that says Doctor V64 HDD V1.30B.




When on the main menu,you can press the CH button on the V64 to switch between HDD / CD mode (displayed on screen). This will ONLY work on the main screen though.

The BIOS is based on the old 1.30 V64 BIOS, so you won't get any of the new fancy features or test menus.

If there is ANY type of corruption of the file system at all (or other problems), it will probably freeze the V64 or keep loading indefinitely. There's a very small possibility that it could end up randomly writing to the drive / CF card as well, so watch out.

The V64 PSUs usually suck, so you might need a separate PSU for bigger / older HDDs. Plus, it will only read up to 128GB from a drive (if it even works).

It doesn't work with all hard drives/Cf adapters but what worked for me was the Ide2Cf adapter "ADIDE2CF-A1" using a Sandisk Ultra 4gb CF card.


I also tested an old 4gb hdd from 1995 and it worked fine;).

That cd-rom cover from an old tower came in handy.


Thanks to Marshallh and OzOnE_2k1 for helping me with this.

    Thanks for the tutorial.
    I have doctor v64 bios v 2.02 with a cd-drive
    when I am trying to boot up games I receive the following message : no cd or drive error.
    Will it help if I will downgrade to this version?
    Thanks
