Try this way.
1. Rename CHD file to 1.chd (for ease of use).

2. Extract CHD = chdman.exe -extractcd 1.chd 1.toc 1.bin

3. Delete 1.toc (not needed).

4. Create a cue sheet for the bin file = bin2iso.exe 1.cue -c 1.bin

5. Edit the cue sheet with notepad, find the last track and edit "AUDIO" to "MODE1/2352" then save.

6. Open the cue sheet with isobuster and extract the last track (Extract RAW Data (2352bytes\block)(*.Bin,*.Iso))

save as or rename to track03.iso (for ease of use).

7. Now use gdrom2rom to create a decripted rom and lst file put both these in a folder with the games name

and now delete bin cue and track03

Check the photo thread for proof it works.
