This is something I have actually already done some years ago. I still have my GBP and the disc from when I bought it (waaaay back when). I don't remember seeing anything interesting in Dolphin, though I'm not a GC expert. Ideally, I should have just inserted my own print/output statements into Dolphin's source code to watch ARAM DMAs more closely. However, I suspect most of this stuff was already figured out by the people behind the Game Boy Interface. They probably know exactly how the GBP works (since they made replacement software). However, I don't think the source code for the Game Boy Interface is available...
