Summary

Building TPM used to take two of your own files: the executable, extracted by hand into the gitignored components/tpm/tpm-decomp/disks/us/, and the disc image for the movies. A fresh checkout gave only the warning that SLUS_008.84 was not found.

Now CONFIG_TPM_DISC_PATH is the only setting:

• If there is no file at CONFIG_TPM_EXE_PATH, CMake extracts SLUS_008.84 from the disc image into build/esp-idf/tpm/disc/. It extracts again only when the image is newer than that copy.
• The executable's SHA-1 is checked against USA Rev 1 (the value already in tpm-decomp's splat.us.yaml). Any other file builds without the game and warns, instead of recompiling into something that crashes.
• The warnings now say what is missing and which setting to use. With no input: "no SLUS_008.84: set CONFIG_TPM_DISC_PATH to your disc image (or CONFIG_TPM_EXE_PATH to the executable)…".
• CONFIG_TPM_EXE_PATH still works when the file exists, so existing setups are unchanged.
• Kconfig lists the disc image first, and its help text says it is the only setting a build needs.
• The top-level README's Build section and components/tpm/README.md say to set the disc path.

tpm-decomp 00fcb3b: tools/extract_disc.py <disc> <outdir> NAME... extracts just the files named, matched by path or basename, case-insensitively. It exits non-zero if one is missing.

Testing

Local configures:

• Only the disc path set (no disks/us/SLUS_008.84): extracted, "recomp: 1573 functions, 121575 instructions -> 16 files". A full build succeeds with the runtime and the game linked.
• CONFIG_TPM_EXE_PATH pointed at a wrong file: the not-USA-Rev-1 warning; builds without the game.
• Neither set: the new "no SLUS_008.84" warning; builds without the game.

Not flashed to the board; the generated code is the same as before.
