Are they very reliable? I had two for my SMS and one of them already wasn't working when I got it, although maybe it had an abusive owner (I had bought everything used). So I can't really comment on them.
It might've been the exact two you have pictured, actually!!
I know I played Ghost Manor and I know the other one (that didn't work) was a tennis game. Was there more than one tennis game for the SMS? (Yeah, I had one, but I'm not real familiar with it's library; didn't even play 50 games for it, and there were a lot more than that!)
