@rodkplay1111@PKMN_twt I followed this tutorial to install it; some games require overclocking if you want to avoid problems. In my case, I tweaked the performance a little bit for HeartGold.

@rodkplay1111@PKMN_twt It's really not that complicated. I simply downloaded a Melons emulator to my OLED Switch. I also have a DS, but unfortunately the charger broke, so I opted to emulate DS on the Switch, and it's actually worked out quite well!
