I never had one, and often lamented it!
Being able to pause a running game and peek/poke at the RAM would have been very useful for hacking games, though of course I'd still need to crack the loader to share the POKEs with other people.
Oh it was. It had its own handy interface where you could alot of things live in the memory. I remember hacking for infinite lives/credits and finding out secret passwords. It was a very fun and very expensive ( for me ) device. I did not need it for copying games. There were some local hobby clubs which had almost every game and software.
