This thread inspired me to get a lot of Chiptune, I'll link what I have. (a bit uncertain at come if they count as chiptune or not)
*Alex Mauer - Eat People 1,2,3, Lo-Gear and Vegavox 2
*Anamanaguchi - Power Supply
*Metronomnomnom - Psilodump
*She (Discography)
*The Depreciation Guild - Nautilus, In Her Gentle Jaws
Sonata probably knows best about where to start, and what kind of stuff I have.
