Questions
What parts does the SuperGrafx Schematics use?
16 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the SuperGrafx Schematics KiCad files?
From the rgalland/PC-Engine_SuperGrafx_Schematics repository on GitHub, at the commit this page was made from: the board is SuperGrafx_Schematics.kicad_pcb and its schematic SuperGrafx_Schematics.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SuperGrafx Schematics design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
