Settings lists the internal storage and every mounted drive (/mnt/extN,
/mnt/usbN) with its free space. New downloads go to <drive>/patchdl on
the chosen drive and install from there. A title keeps its folder on
the drive where it already has one, so packages downloaded earlier are
still found, listed and installed; while the chosen drive is unplugged,
downloads go to the internal storage. Config and caches stay in
/data/patchdl. Closes#18.
The tile's param.json sets applicationCategoryType 65536, which puts it
in the Media section. The home screen keeps the section a tile was
registered in, so an older tile is uninstalled once and registered
again. Closes#19.
Write param.json + icon0.png into /user/app/<TITLE_ID>/sce_sys/, then
call sceAppInstUtilAppInstallTitleDir to register the directory as an
app. No package, no code signing — the installer reads the metadata
files directly.
The tile uses TITLE_ID PTDL00001 and deeplinkUri
http://127.0.0.1:12880/, so tapping it opens PatchDL's own UI in the
on-console browser. Only useful while the ELF is running.
Asset pipeline: param.json + icon0.png live under assets/ and get
.incbin'd straight into .rodata. Makefile lists them as TILE_ASSETS so
a touch on either forces a relink.
Stat-guard: file_matches() diffs each asset against the on-disk copy
first; when nothing changed the install API isn't called at all. Keeps
repeated payload starts from re-registering the app. Repeated
/api/install_tile calls return "already installed and up to date".
Backend lazy-load: AppInstUtil isn't mapped until something pokes it,
so the helper polls patchdl_install_backend_check() for up to ~15 s
before resolving sceAppInstUtilAppInstallTitleDir.
Wiring: /api/install_tile POST triggers the install on demand;
patchdl_websrv_start() runs it at startup when home_shortcut is on;
and flipping the toggle from off to on in /api/config also fires it.
All three paths share the stat-guarded helper so they're safe to
repeat.
