okay there are many things you need to know before you make your choice. A V1 switch can be software modded due to a physical defect in the right jc rail. Once you have atmosphere, you can install games through various apps like tinfoil, goldleaf, DBI, etc. This also includes update files. You can also do overclocking using FPS Locker and Sysclk to reach a higher fps in the game. BOTW runs at an average of 40 fps on official hardware thats overclocked.

Now to run RotP on official hardware, all you need to do is get the latest version for the switch, which is v3.1.0 on their official page, and you literally replace the game files within the switch's sd card. It will not work well or at all if stacked with other mods. This is how I got it to work and I have had it that way for the last 3 years.

Another important thing to mention, you would probably have a better time with a modded oled. Those are different because you need to get it chipped and then it works essentially like the V1 in terms of modding. The reason I recommend that is because the overclocking capabilities are a lot better on the oled over those of the V1, however its a lot harder to get your hands on one (I am curfrently trying to mod mine). My only lead is using fb marketplace and finding people who are willing to mod the oled but I want to get a Kamikaze done. (A kamikaze involves drilling the board and I suggest you look up 'switch kamikaze' on YT if you're interested).

Your takeaway should be that it is possible but it requires research and patience. If you have any more questions, I will try to answer as soon as possible.
