the switch 1 has a pretty cool homebrew community. you can run linux on it now (they've specifically ported Ubuntu and Fedora). and that means you can play any game that runs on linux, or can be easily emulated on linux.
also, if your switch 1 was made in 2018 or earlier, it has an unpatchable hardware exploit that makes it super easy to load custom programs at boot time. the exploit tool is designed to make no changes to the switch's internal storage, everything you do is saved on the SD card only. if you eject the SD card and reboot then its just a normal switch again! if it was made in 2019 or later it probably has patched hardware, but you can solder a bypass chip to it for about $50 in parts (and you can get someone on etsy to do it for you for around $100 in labor, last I checked).
so basically it's extremely low-risk and if you weren't using your switch anyway then hey now you have a pretty damn cool portable linux console. ive been using mine to play retro homebrew like o moku e mun :D
