# Set up the DuckStation oracle build:
|
|
# 1. Ensure duckstation/ submodule is initialized and at the pinned upstream commit
|
|
# 2. Fetch + extract Windows prebuilt deps if missing
|
|
# 3. Rewrite stale absolute paths inside the extracted deps (artefact of how
|
|
# upstream packages them — the prefix is baked in at pack time)
|
|
# 4. Apply the PSXRecomp oracle patch (psxrecomp_oracle.patch) if not applied
|
|
#
|
|
# After setup, run `tools/duckstation/build.sh` (or the commands in its tail) to
|
|
# compile duckstation-qt.exe into duckstation/build/bin/.
|
|
#
|
|
# Safe to run repeatedly — each step checks for "already done" and skips.
