With modern games you have to wait for like six hours for the stupid thing to download, if you even have the hard drive space to redownload it in the first place
Is that hassle worth it just to revisit some game from your back catalogue for half an hour? Eeeeeeeeeeeenh
Instant load times and no launcher or menus telling you to buy things
I just timed it and it took six seconds from power on to being in-game (as in, save loaded, controls active) for Pokémon TCG for Game Boy (Color). Zelda for NES took four seconds. Doesn’t get much better than that!
