How did you mod your switch? Any tips?
Discussion
If you have switch v1 (old model) then it's very easy. You just have to install software mod (Hekate and Atmosphere) by following tutorials on YouTube.
If you have switch v2/oled/lite then you have to buy picofly mod chip and solder it on your switch. And then you install Hekate and Atmosphere.
I got a guy in a video game store to do it for $70 (Picofly Chip + Soldering + Installing Mod Files).
Since then I have probably played 100s of games for free, on my switch.
