This is the data a neogaf user tabulated right? Nice to see it in graph form anyway.
I also have this bookmarked if you want to do anything with it: https://docs.google.com/spreadsheets/d/1_ktRB2qmldCTsto2HFhGCK9V9W6D07RfaWlnfGYypCk/edit#gid=0
Someone recorded the quarterly shipments of everything including breakdown by SKU (there are 3 sheets, one each for handheld, console & a graph), unfortunately whoever made it stopped updating in 2016, and I think Nintendo only recorded every 6 months before 2003, but makes it easier than trawling through Nintendo's old IR reports.
