I have a couple dozen Wii VC games I want to take the WADs of, convert them to ROMS, & put them on my Wii U & New 3DS XL. First, I want to learn how to do this as I find it interesting. Second, I feel I am in over my head in not knowing what to use in trying to take the VC games off my homebrewed Wii & on my PC. May I have some help here?

Yes and no and 99% of the time just go download the ROM, indeed might even be 100% as most of the first official translations/fixed versions on Wiiware are available too (possibly even as patches) and those few occasions where they might have gone for a censored version then might as well get the original.

Yes. Use whatever you like to get the wads from the console, or from the iso (there are some games with VC and other demos onboard, https://wit.wiimm.de/ or wii scrubber for ISO fun). https://wii.guide/sr_SP/dump-wads.html and possibly showmiiwads
Once you have them then whatever tool you like to pull them apart (I think we are still suggesting libwiisharp https://code.google.com/archive/p/libwiisharp/downloads example programs). Chances are it will not be named what those in the emulation scene will be calling things but it will likely be fairly obvious by the size alone.
From there it can vary. Nintendo was quite famously caught using the ines header that emulators use but I have not seen what goes for all the consoles emulated by the Wii. Similarly there has been a history of different formats to that which the "homebrew" emulators might expect used by "official" emulation. For the most part you can probably get away with finding whatever tool ROM hackers and emulator fans use to create the headers or fix the formats ( https://www.romhacking.net/?page=ut...&level=&perpage=20&title=&desc=&utilsearch=Go has a bunch, and whatever emulator scene for the console you are looking at will likely have a bunch more).

More importantly though, which is where the no aspect potentially really comes in, I think some of the consoles emulated use external sound files rather than emulate the sound core/code (it is certainly a popular approach then and to this day). Now you will probably still have the original sound in the ROM and replacement all handled at emulator level but something to note.

For the Wii U some might say just leave it as wad and run it under vWii instead. I don't know the current state of Wii U homebrew emulation (or indeed what goes for the Wii U's own take on virtual console*) for all consoles covered by the Wii but if it is the superior alternative then play that as you will, or in some cases Wii VC might be valid for speedrunning (I know Mario 64 has some extra bugs on VC that change how some things work there) where emulated on homebrew emulators by the Wii U might not be.

*I assume you would run whatever Wii U equivalent there is in that case, if though you are injecting things that were on the Wii but not on the Wii U into the Wii U's take on emulators, which could vary between games on the higher end consoles in the range, then yeah.
