eboot invalid or unsupported format help

[MitchMitchMitch]

Will "3k3y ISO Tools" work as "an appropriate extraction tool" (step 9)?

I don't think so. I just use 7-Zip. You can also mount the decrypted ISO using mounting software like Daemon Tools and use Boot Game to boot from the virtual mounted drive if you don't want to waste space.

Thanks for all of your help for real, it was very much appreciated and very helpful.

For future troubleshooting, I found out you can use 3k3y ISO Tools for extraction, and it will work without corrupting the file. I got it working!

I figured out the step I messed up on was patching the incorrect IRD to my ISO (most likely ruing the ISO)
So I basically started from the very beginning just to make sure I did it correctly.
I made sure that I downloaded the correct IRD BLUS30443 instead of BCAS20071 from the website http://jonnysp.bplaced.net/
I did this because I didn't properly understand this little tidbit of information my first time reading through it...

Please note that it is very important you use the correct region ID.

it was pretty easy to forget that information when I started reading the dumping section. A simple mistake easily overlooked. It makes it a little funny too because there was even a section that says the proper ID for Demon's Souls.

I have the game up and running, I really couldn't have done this without your assistance. I was able to think in the right direction because of it.

Again, thank you for your patience and support! I am certain you come across a lot of duplicate threads, hence why I used the search funtion and used this post to recieve assistance!
