The pgraph tester has tests for float depth modes (you'll just need to reenable the d24s8 one that can't be run on xemu: https://github.com/abaire/nxdk_pgraph_tests/blob/main/src/tests/depth_format_tests.cpp#L21) |

Nit: if not f: would be more pythonic (here and below)

Can we use symbolic names for these rather than the raw values?

Let's just remove this since it's never invoked.

I don't think python implementations do a superb job of optimizing, I'd extract out some of these values that don't change.
E.g., move the y * pitch out of the x loop, move fmt.bpp // 8 out of the loops entirely

Nit: I think you can drop the explicit != 0

Nit: I don't think you need to explicitly check against None here, just if stencil_img would be more pythonic since anything falsey is not going to be callable.

Note: Depending on whether this goes in before or after #42 we'll want to expand this path to capture the draw count and depth_offset

Produces an image representation of the depth and stencil buffers. I don't have any games that use float mode or swizzling (to my knowledge), so I'm unable to test those formats.
