I did a new conversion of C-BIOS 'cause Stokes's one is messy, pretty good compatibility but the sound is not working. Almost all games already posted here with Joy Soft loader are running with this C-BIOS, so now running on real hardware! (without the need of DahJee RAM extension adapter). Example with the homebrew Bubbo World 2 attached.

For the conversion of C-BIOS I used the first 16ko of cbios_main_msx1.rom from cbios-0.29a.

Then I changed all this value:

D3 98 --> D3 BE
D3 99 --> D3 BF
D3 AA --> D3 DE
DB 98 --> DB BE
DB 99 --> DB BF
DB AA --> DB DE
DB A9--> DB DD

Then for the sound we have originally:
D3 A0 at $1753 and $175C
D3 A1 at $1757
DB A2 at $175E (maybe controls?)

I don't know how to change this 3 values, sometimes I can get sound but not proper.

Sorry to ask Revo but what is the correct way to use that modified bios ?

Revo wrote

Grog's Revenge is now playable with C-BIOS. Pretty fun game.

To start a game push button 1 two times then button 1 of second controller and then button 1 of first controller.

Dope, thank you for giving new strength to this thread!

You are very welcome Revo. BTW for one question, how do you make the Clover or Hi-Com loader get pass the SMS US/EU BIOS (or in a simple way: How did you get the MSX loader to have a header and work on the Master System USA/Europe BIOS)? Thanks in advance. :-)

If there's code or content where the header needs to be, you'll probably need to use a disassembly to move stuff around. Emulicious can produce one for you.

The easiest way would probably be:
- Make sure you've relocated any code or data that's in the way
- Test to make sure your ROM still works in an emulator
- Use a hex editor on an export SMS title, go to $7ff0 and copy everything up to and including $7fff
- Paste that over the same area in your ROM
- Optionally blank out the product code and version number (probably a good idea to make sure it doesn't get confused for an official release)
- Optionally change the last nibble to $c, to skip most of the checksum and reduce the boot time slightly
- Use the header reader to get the correct checksum, then hex edit that in (you can skip this step unless you're planning to burn the ROM for a donor cart)

Per the documentation on the wiki, the checksum is two bytes at $7ffa. To get the correct checksum value, I've been using Maxim's header reader, then going in with a hex editor and fixing it manually. I've only done checksum fixes, but you can find all the information you need in that first link to make a full header. I believe that you can get away with making sure that the first 12 bytes and the last 4 bits of the header are valid to ensure it boots everywhere.

Final note: If relocating code at $7ff0 is going to be difficult, you could also check out $1ff0 or $3ff0, though these aren't used by any known software so you'll be relying on a perfect implementation on whatever's running the ROM. Also, I don't know whether Maxim supports these locations in the header reader, so you'd be on your own fixing the checksum there (though, I never needed to fix the checksum to run on my Mega EverDrive, so maybe you can get away with ignoring that, unless you plan to burn the ROM for a donor cart).

With an HEX editor put TMR SEGA at $7FF0, put the value 4C at $7FFF then use SMSandGGHeaderReader to put a valid checksum at $7FFA.

Revo wrote

Just slide the rom into it, then put the valid checksum with your HEX editor.

"Calculated= xxxx"

Followed update for Car Fighter and Ice World.

Glitch on text fixed. Header & valid checksum added.

Hello ,
I've tried on real Master system , and the result is very good

1) Keystone Kapers = work good but have sound issue , have you planned to upgrade the sound ?

2) Sparkie = i can't start the game because bouton 1 & 2 of joypad is not working to start the game , is it possible to remap joypad for keyboard 1,2,3,4 ? (but is see the demo work good)

3) Can you explain how you converted Keystone Kapers and Sparkie ?
(i want to try to convert Eggerland and Rambo...)

4) Have you planned to do a software (on PC) to do this automatically ?

5) is this method can work with MEGAROMS ?

Best regards

Hello ,
1) For Keystone Kapers [a2].sms , the sound working good now

2) For Sparkie when i push 1&2 during demo, the game start
but i have sound issue on Sparkie
Can you modify the sound like "Keystone Kapers [a2].sms" for the sound of Sparkie ?

3) Can you explain how you converted Keystone Kapers and Sparkie ?
(i want to try to convert Eggerland and Rambo...)

I also fixed the sound on the C-BIOS for SMS. I will send it soon.
