@liviux76 that's great to hear!
Uploaded a temporary TEST version of the intro executable for anyone having problems. If it can't see enough chipram to run the AGA mode it should gracefully downgrade to ECS mode, and even if it still can't allocate enough memory it should gracefully quit rather than guru. This is the executable only so you'd need to drop it inside the folder of an existing install to run it.
Please let me know if this does or doesn't fix intro issues.
