SNES Controllers (sneak peek) (Patreon)

Content

As I wrote the script for this video, I considered breaking it up into two parts, one for the SNES side of things, and the other for the controller side of things. But I ultimately decided to just bundle it all together. That meant that this video is now the longest of the series, and almost tied for longest on the entire channel. Oops!
I really wanted to explain more about the Super Scope, since it has a very peculiar way of working, and a lot of caveats that stem off from its methods, but I think going all the way to the nitty-gritty details would go outside of the scope for this video series. Maybe I'll make another video just for the Super Scope that goes even more in depth.

Controllers - Super Nintendo Entertainment System Features Pt. 08

How does the Super NES gather input from such a wide variety of controllers? It's all explained right here.

You keep referring to things like "CPU register $4001". I'm assuming you mean the memory location. Why call it a register in that way?

And at 15:54 you refer to "address $4201".

Short answer: I call it that because everyone else calls it that. Long answer (this will be explained more in the next video): A register is a place where data is stored within the processor itself. CPU register $4201 can be abstractly seen as an 8-bit value held inside the CPU. Under that layer of abstraction it is really just a connection to pins 19-26 of the processor. These registers are memory mapped, so they, like WRAM, SRAM, and ROM, are given a subset of the address space they can be addressed by. The SNES CPU gets the $42xx region, and the PPU gets the $21xx region.

The terminology is kind of corrupted in a way because they are all used interchangeably... Though technically it could be "CPU register $4201" or "address $4201", but calling it "'memory' address $4201" would be incorrect, since it's not a reference to any memory. I also very often erroneously call the PPU registers CPU registers instead. Usually when referring to both at once I call them "hardware registers".
