Sorry to say i do not have 50 posts yet, bit of a lurker/slacker, therefore unable to up my archive to ftp .. yet! Never said which weekend to be fair
What I can say is the demo was pre-installed on my cf card when i purchased the 3.1.4 roms from amigastore.eu. This doesnt help matters, I appreciate. All the demos on the card actaully worked (there was about 20), a mixture of aga and non aga demos. About half i nabbed off a whdload demo archive do not work though.
Hope you figure it out though, will do some tinkering here to see what the issue is also.
