You can use Nologic's CHD to GDI tool that was linked above.
If for some reason this fails, please let me know which .chd you want to convert and I will try to do it manually.

Some XML file is needed for that tool and I don't have it I only have the CHD.

Jikkyou Powerful Pro Yakyuu - Dreamcast Edition v1.003 (2000)(Konami)(NTSC)(JP)

I just ordered the disc but it is coming from Japan so it will take some time but this is for a good friend of mine so I want to make it ASAP. BTW new NTSC-U dump on the way, not much but needed Buzz Lightyear of Star Command.

Unfortunately I don't have the data for this one, but luckily I can supply you with the .gdi file contents:

Code: Select all

3
1 0 4 2352 track01.bin 0
2 450 0 2352 track02.raw 0
3 45000 4 2352 track03.bin 0
Look at this topic from AvS to see what to do.
First you extract one single .bin file from the chd, using this command:

Code: Select all

chdman -extractcd jikkyou.chd jikkyou.toc jikkyou.bin
If you don't have chdman, it can be found in the regular MAME pack.

The last 1.185.760.800 bytes of the jikkyou.bin file are your track03.bin. Chop them off with a hex editor or something like that. This is the only thing you need to rip the game. :)
Hope this is clear and easy enough to follow. If you still have a hard time with it, point me to a place where I can find this .chd and I'll do the job for you. :)

I think I can handle that, if not I will let you know. I can at least get it ready for hexediting for sure. Might PM you on how to rip out just that data.

The XML file needed if I recall is the ClrMamePro DAT file from Tosec...as the script needs the file size's to know how to cut up the resulting Mame CD image.

However it's my understanding that CHDMan now supports producing a full blown GDI rip...in it's latest versions...so my scripts are no longer needed (thank god)

Okay just tried it...and seems to work fine...but everything is dumped like Redump so all file extensions are bin.

Code: Select all

chdman.exe extractcd -i <DC.chd> -o <DC.gdi>
