As we all know, the most used bios for Chankast that was released is a PAL/(Span)ish BIOS. Many people have said it is the only annoying thing with Chankast since most people including us were not able to find a NTSC/(Eng)lish BIOS or we couldn't flash it from our own DreamCast's.
We have now found a way to modify your preexisting PAL/Spanish BIOS to a normal NTSC/English BIOS, better yet, any combination you want with even more languages to choose from!!
I. What you need:
- Hex Editor (Choose Between: Hex WorkShop | XVI32)
II. Unzip Sega DreamCast Bios
Unzip the Sega DreamCast Bios if you haven't before (If you have already done this step if you played Chankast already, skip this step, if this is your first time with it all, keep reading) using WinRAR.
III. Open the Hex Editor (either Hex Workshop or XVI32 is best)
Open dc_flash.bin, then Search down through the file for "211Dreamcast" (its about 4/5 of the way into the file, just before a list of the japanese developers' names). Change that 211Dreamcast to 121Dreamcast. That string appears twice. That string appears twice. It worked with just one changed, but its probably a good idea to change both instances.
IV. Save the DreamCast Bios
Save the bios over the prexesiting original, we also recommend you keep a backup of the original just incase you mess up.
Your bios is now a normal NTSC (with the Red Swirl, PAL is with the Blue Swirl) and it's in English too! If you would like to request a different language or combination, reply to this post and we can help you out.
Notes: To change it to other languages yourself, you have to change the second digit to other numbers (either with the prexisting PAL combination or NTSC combination). Feel free to play around with it. We can't guarentee if this won't screw up playability with other games or make it any better, so try it out both ways (original and your own) and see how it is.
