Fullsnes is a large hardware reference for the SNES created by nocash.
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]
- In https://problemkaputt.de/fullsnes.htm#snesapudspvolumeregisters, MVOL should stand for "main volume," not "master volume" because MVOL does not control the echo volume, and the offical docs say so.
