Space Moster / Spider Moster

I recently got the attached cartridge "Space Moster / Spider Moster".

It seems to be this cartridge, just with a different label:

I also found this old post from 2001:

But the description does not match. It has the same typo, but the front and end label is different.

Can anyone read the end label?
