My experience is that the SD to CF adapters do not work properly so try to get an original Sandisk 4GB or 8GB CF card.
As for LEDs what about the Red one is it on constantly ?
@magicman nice to see the WD worked, what cables and what settings did you have on the drive ? I.e. were they both MASTER ?
Can you share a picture of your CF adapter ?
And did you try with an 8GB CF card and a trimmed image ?
My cable has labels, BLUE is system, GREY is slave and BLACK is master.
Set your CF interface to master and try that.
As I also said, try truncating the image to 3 GiB and using a smaller CF card, 8 GB should work,
@magicman just use a straight IDE cable and set the CF adapter to master. Some IDE cables have both a slave and master marking in that case choose master. Some are straight.
The actual disk data is actually only 3GiB so you can truncate it and try a smaller card like an 8GiB.
What do you mean by extract the ISO ?
I found the NM00009 game.
@defor If I use isobuster on the file: NM00009 NPY1 CD0C (CD-ROM).iso, I do not find a file system.
If I use the image from MAME all is good and I find: RB_ARC and the file: RBA.DAT
Here is some technical differences between...
@El_isra thank you for your hard work on this.
Is there a place one can follow the development ?
I would really like to use my sd2psx to play Gradius V but last time I checked it was not supported ?
You are on fire @alamone ,I guess you have seen the Konami announcement.

Now the question is, why no Gradius IV or V ?
