The PSP numbers are all over the place, but generally they are around 80m. According to Wikipedia:
"PlayStation Portable: 76.4 million units sold as March 31, 2012. [...] IGN's Evan Campbell reported around 80 million sold on June 3, 2014"
Here (http://www.guinnessworldrecords.com/news/2018/12/top-10-best-selling-videogame-consoles-551938) it says it's around 80m, and it's a relatively recent article.
