Fullsnes is a large hardware reference for the SNES created by nocash with several ascii art illustrations.
Errata
- In https://problemkaputt.de/fullsnes.htm#snescartridgecicnotes, the formula for the Polynomial Counter is missing an inversion in the second term.
- In https://problemkaputt.de/fullsnes.htm#snesapuspc700ioports, it could be clearer that bits 0-3 of TnOUT are reset to 0 automatically by hardware after reading - it is not the programmer's responsibility to zero them after reading. [1]
