I have no idea where to even start. All that I know is that once I get the file format into .spc I can get into Winamp and convert.
You should be aware that an SPC is not exactly a piece of audio data, like a WAV or MP3 is (compressed or not compressed doesn't matter). SPCs are machine code, interpreted by software (synthesizer).
It's comparable to MIDI - MIDI being more abstract (SPC uses special machine code, which can only be executed by special software - MIDI does work with any MIDI sequencer/synthesizer).

I already have a .wav to mp3 converting method that works well so I'm OK there.
Does it involve LAME?

Specifically, I would like to rip N64 games and Dreamcast (for which I have a DC to PC connector that is useless without something commuicating to both). I've seen the threads for PS2 ripping and I even saw the NES thread that mentioned getting from .spc to mp3 format, but the writer assumed that no one needed the help in getting the base format, which is what I need.
There is a nice overview about PSF ripping (I think Zophar has the docs). You should check this first - maybe you don't like the technical stuff.

Ah, yes. Here is the link: http://www.zophar.net/psf/

At first sight it has nothing to do with N64/GC ripping, but you should find docs that use an analogue aproach for this kind of ripping.

EDIT: Of course you can also use the (low quality) analogue recording approach.

Jam it back in, in the dark.

I just wanted to add that this line-recording approach is really the last resort because it means at least two conversions (digital-to-analog on the console side and analog-to-digital on the recording side). And both the DAC on a console and the ADC part on the common soundcards are not the best in general.
You get both noise introduced by the DAC/ADC and noise/distortions from the different ground levels the systems are operating on.

You better learn assembly for direct ripping of music data. AFAIK the PS2 music format is well understood. This also applies to N64 and maybe Dreamcast (I'm not really sure about that).
Information about file specs can often be found on emulation sites or (if open-source) in the emulator source.

There's nowhere I can't reach.
