NAOMI CHD 2 GDI

You can convert all Naomi .gdi raw dumps to the corresponding Mame CHDs, using:

Code:
chdman -createcd <my.gdi> <my.chd>

But reverse process is quite easy, using:

Code:
chdman -extractcd <my.chd> <my.toc> <my.bin>

Very first bytes are track01, very last bytes are track03.
You just have to perform some basic subtractions in order to obtain track02.


NAOMI GDI 2 DECRYPTED .BIN

A. Mount track03.bin in a virtual drive, using .cue file

Code:
FILE "track03.bin" BINARY
TRACK 03 MODE1/2352
PREGAP 10:00:00
INDEX 01 00:00:00


B. Extract the main game .BIN file, using IsoBuster

C. Decrypt the extracted .BIN file, using 'DEScrypt.exe' (from Makaron T11) & the corresponding PIC Key

Code:
DEScrypt <key> <game.bin>
