Online if there are platforms that allow you to try the games without downloading, although for my preference the download is better because as they are retro games, they do not weigh 200MB and if they need emulator then the weight is reduced more, anyway if there are platforms for you to try them online, just recently by mistake I found one and I started to play a random game, if I get its name again I will write you if you are interested.
Thank you for your comment
Yeah share it with me here and I'll take a look to it.
ok, let me look for the page again and pass it to you by Discord if you want.
Cool idea. You can send me from there.
