Here is new easy way to extract/decrypt naomi CHD using MAME 130u1:
Start any Naomi GDR game using MAME
Wait message "Type OK or move joystick...." then press Esc
Look into MAME root dir - you see two new files here "decrypted <gamename>" and "encrypted <gamename>"
Just rename "decrypted <gamename>" to some thing like game.bin, make LST file and run it with nullDC-Naomi

example LST:

Code:

Game Name
"bin-file-name",   0x0000000, <length of bin-file-name>
