I've been playing your simulations for a few weeks now and I just discovered you can play the alarms on all the game & watch games! I'm totally blown away by the amount of detail you put into each game. Thank you for making such an amazing collection!
You could set them up on your bedside cabinet (I seem to remember a little wire stand pops out from the back of some of them to prop them up), batteries lasted forever so would have made a good alarm clock for kids. I don't think I ever used to wake up to an alarm as a kid though, but handy to check the time.
I have a strong memory of my dad becoming a bit addicted to my Donkey Kong dual screen when I was about 12, one day I left for school and he was sitting up in bed playing it, and when I got home he was still playing and shouted at me to not disturb him as he was getting a high score... haha.
