cheers glurk,
Thanks for that.
I've been thinking the same.
I know many of the game roms are actively available for download but it's possible they were just released some years later?
It was reported that Scott Adams did release everything they had ever published (and possibly many games they hadn't...).
I have spoken to him about the CoCo releases as well and he couldn't remember, which is expected after 40 years.
I've posted on the FB CoCo collectors page as well and no one there seems to have seen physical releases of any of these games either?
What a mystery...
