AFAIK, Batteries in pokemon cartridges were only for the in-game clock, not the actual save files! So he is not safe!

Edit: i stand corrected! Ive never had or worked with pokemon carts specifically, but i have worked with & modded a lot of GB, GBA and N64 carts and not all of them have batteries, in fact most dont. I know n64 mempaks do, tho, but almost none of the carts. Info i had gathered from the various retro communities led me to believe that GB/GBA pokemon carts were a type that didnt need a battery for the save file, only the clock, but apparently that isnt always the case!

So i used to dabble in doing jobs for Amazon’s Mturk work system to try and make some extra money. I’m not gonna go into the details of what that is or how it works here, but we would get a lot of little jobs that could be “write out closed captions for these short videos”, OR “select any squares of this image that meet the request”, like on this post. We’d be allowed to not select any squares if that was the case. They always looked like screen shots from google earth or something. A lot of times, like here, the solution was not in the provided image. I always felt like us Mturk human workers were providing the solutions to these “anti bot” measures.

Their dvd library went to shit a looooong time ago, so to echo some other comments here- i’m surprised the service was even still around. I used to get multiple discs at a time. (i think they had a 3 disc at-a-time plan where you could send one back and they’d send you the next in your cue, but you’d always have 3 at home.) Then as streaming started to take off and they started making their own TV shows it seemed like there was less and less DVDs for rent, and not just because id watched them. I was getting notices of things on my “wish list” or whatever about to become unavailable, or movies i wanted to rent again were just gone from the library. This effected movies, documentaries, TV series, lots of different content types. They rolled streaming into my plan for free and i eventually gave up on discs entirely and just canceled that part of my plan, sadly. Eventually completely canceled everything a few years ago, ended up never using the service anymore. There’s my experience no one asked for!
