No, it is not. There may be some components that didn't change at all from 1.3 to 3.1, but these would be countable on the fingers of one hand. I suggest you name those components and let me and others verify by comparing the binaries. Exec library did definitely change. Trackdisk device may be the same, will have to check.

> some has problems with reality

I suggest a look into the mirror.

> Hyperion may do what they want with 3.1, cutting 1.3 from 3.1 also.

I doubt that the 1.3 source code is a true subset of the 3.1 source code. This wouldn't make sense. As said, used programming languages changed for many components. You can't cut ASM source code from C source code, for instance.

> What Hyperion do is full compliance with the agreement and perfect legal.

In my opinion, Hyperion distributing 1.3 is compliant neither with the agreement nor with EU or US copyright law.
