Sets up this project as the native pipeline's scaffolding plus RetroArch's
sources, so RetroArch is compiled for the title pipeline rather than converted
into it.
- tools/scaffold-native.sh builds the scaffold from
../ps5-native-app-boilerplate-main: tooling, runtime (digest verified),
Makefile and its tools, merged into this repository's tools/ rather than
replacing them. An earlier version replaced tools/ wholesale and deleted this
project's own scripts; the copy is now additive and the reason is in the file.
- tools/fetch-retroarch.sh clones the pinned upstream tag into vendor/ and
records the revision, so "built from RetroArch 1.22.2" is checkable.
- src/display.{hpp,cpp} owns the console's display: VideoOut, direct memory, two
registered buffers, present-and-wait. The sequence and its two load-bearing
details come from the sibling application that proved it on hardware.
- src/main.cpp draws a moving bar: the cheapest thing that proves build, title
format, launcher, VideoOut and the direct-memory path together.
- sce_sys/param.json is this project's identity, PPSA99169.
Evidence: src/display.cpp compiles through the pipeline's compiler
(tooling/prospero-clang18 with PS5_CLANG=/usr/bin/clang, -std=c++20), and a
RetroArch source file compiles the same way with its include paths.
