None in my area. I just was crazy for the idea that the home system and the portable took the same games. I remember trying to convince my mom that we’d only need to buy a game once for both systems… She did not bite. We had a NES and a Gamboy.
Can confirm, i never do this. Have terrible battery life. Instead of becoming less of a slacker, i just have twice as many batteries waiting. It's easier than changing. 🫠
