The log appears to indicate hashing is non-functional for chd on switch, implying the switch build of retroarch doesn't have functional chd support (though the cores themselves may separately). I'm uncertain if this is a bug or simply unimplemented functionality in that build.

[Jamiras]

It sounds like HAVE_CHD is not enabled for the Switch build. The hashing code relies on being able to read the CHD in the RetroArch code and is independent of whatever implementation is present in the cores.

I just verified this issue extends to 3DS as well, and is indeed due to the chd library not being active/present in RetroArch itself. For clarity, I'd recommend an issue rename to the following: [3DS, Switch] chd files can't be scanned or hashed While I'm not 100% happy with that title, it's about as succinct as I can come up with, and it's more clear than the current one.
