# build_sdk.sh - OrbisRPC daemon payload via ps4-payload-sdk (daemon-world
# linkage: no libkernel.so, BSD sockets, SDK libc). Test vehicle: elfldr.

# Usage:
#   PS4_PAYLOAD_SDK=/path ./scripts/build_sdk.sh
#
# The SDK must be built from git, not downloaded from the release ZIP: see
# scripts/build_sdk_from_source.sh for why. Set PS4_SDK_SRC to that checkout to
# have the firmware gate below verify the SDK actually supports 13.52 instead of
# trusting it.

# Checked against source, not the linked ELF: a 4-byte offset pattern occurs by
