After the success of portages such as Quake 1 to 3, here are now the adaptations of Doom on Nintendo Switch, through the Doom 3 and Doom64.
Several options are available to you, or you choose to go on Doom 3, you will have to have the original game with including files pak000.pk4 pak008.pk4 files for Doom3 and 1.3.1 update, and for Doom64EX you must have the Nintendo 64 Rom to have the DOOM64.WAD and DOOMSND.SF2.
Be aware that Dhewm3, the port of the source engine of Doom 3 is very unstable, so it is better to settle for Doom64EX, which is a reimplementation of Doom 64 Samuel "Kaiser" Villarreal. It is based on Doom3D, although it has been rewritten for OpenGL instead of DirectX.
Installing Domm64EX:
Have a Doom64 Rom
Extract the wadgen folder from doom64ex_nx_v010.zip somewhere on your PC.
Run it wadgen / WadGen.exe and point it to your Doom 64 ROM. This should generate the 2 files DOOM64.WAD and DOOMSND.SF2.
Extract the folder doom64ex_nx_v010.zip at the root of your SD card.
Copy DOOM64.WAD and DOOMSND.SF2 to / switch / doom64ex / SD card.
