# PS5 Vulkan Template - the payload SDK this title builds with, at a pinned revision.
#
#   ps5/tools/setup-sdk.sh       install it into .deps/native/ps5-payload-sdk (once a revision)
#
# The SDK is my fork, ../PS5_PayloadSDK: the upstream release with the PS5
# platform layer (libps5platform.a, include/ps5platform) installed over it. The
# pinned revision is exported with git archive, so a build never depends on the
# fork's working tree, and the SDK directory records it, as PS5 RetroArch and
# PS5 vkQuake pin theirs. RADV's archive, its link recipe and the packaging
# tools stay PS5_Vulkan's.
