I want to thank sincerely to GUSVERNEGO to publish the method to extract the chd into the famous track03.bin in ppxclub forums. Here it is:

I found a easy metod to open all naomi chds and save bandwith

1 - Extract the chd
chdman -extractcd xxx.chd output.toc output.bin

2 - Convert to iso
bin2iso output.bin output.iso

3 - Remove sesion 1 and 2
I use File Split Stream 1.0 and remove the first 92160000 bytes (90000 kb)

4 - Rebuild iso
Join all parts except the first and rename to track03.iso

5 - make a cue, paste in the text editor

FILE "track03.iso" BINARY
TRACK 03 MODE1/2048
PREGAP 10:00:00
INDEX 01 00:00:00
POSTGAP 00:02:00

6 - I used cdmage to open the .cue file

7 - Extract the big file

8 - Done!!!!!!!!!

If you rename track03.iso to track03.bin, the can use gdrom2rom to create a decripted rom to Nulldc or Makaron
