I start by using vgmtrans to convert the spc to midi, load it inside FL Studio and just plug in the samples. I use spctool to analyze whats going on inside the spc file and listen to the track channel by channel. If your familiar with Jammin' Sam Miller, he has done the same with the DKC series.
I also live stream my restorations, so you can see the process in real time. So be sure to get notifications from my channel for when the streams are live.
