Hiya,
I was having a browse though various fakebook groups and came across a post from Eric Cubizolle from the Commodore Amiga group.
Dragon Slayer is an unreleased game which was ripped Christian Weber. Eric was kind enough to share the ISO publicly,
Eric's website which is where the ISO is stored is at
http://amigamuseum.emu-france.info
Inside the "Unreleased" section
I Hope Eric and or Christian are members here @ eab and pop in sometime to say hi
In the meantime Thanks to both guys
I have uploaded the ISO in the eab server under ransom1122
