I have registered version of doom 1.1 with blue disks, but my box did not come with the addendum. If my memory serves me right, my game came from the UK and I would like to know what is the difference with these different looking version? Is my copy even supposed to have addendum? My disks looks similar to these:

There is no bold registered text or version on them like there is here:

If anyone happens to know this, I would be pleased to hear.
Thanks!
