Since 1.20 the "Show Memory Stick folder" button and the log folder
button in developer tools call System_LaunchUrl with LOCAL_FOLDER or
LOCAL_FILE. The SDL implementation only handled macOS there, so on
Linux the click did nothing. Before that they went through the
SHOW_FILE_IN_FOLDER request, which already forks xdg-open.
Move that fork/exec into a LaunchXdgOpen helper and use it from both
places. The child now calls _exit after a failed exec so it doesn't
run the parent's atexit handlers.
Previously the cursor was only hidden when entering fullscreen or
starting a game, and never came back on mouse movement. Now it hides
half a second after the mouse stops moving and reappears when it moves
again, which also covers the touch-controls case that used to be
excluded entirely.

naett has had a complete libcurl backend all along; we just never built it,
so Linux ran with HTTPS_NOT_AVAILABLE. That means no homebrew store over
HTTPS, and RetroAchievements talking to plain http://retroachievements.org.
libcurl is loaded with dlopen rather than linked, the same way we handle the
Vulkan loader, so it stays a soft dependency: we need the curl headers at
build time, but a build made here still starts on a machine without libcurl
installed - it just reports HTTPS as unavailable, exactly like today. Distro
packagers get the behavior they'd expect either way, and certificate
validation comes free from the system CA store.
New net::HTTPSAvailable() answers "did that work", and SDLMain folds it into
SYSPROP_SUPPORTS_HTTPS, which everything downstream already degrades on.
Four fixes to the backend itself, all noted in ext/naett/README-ppsspp.md:
- panic() called exit(1) on a pipe or curl_multi_perform failure. Taking the
emulator down because a download failed isn't acceptable - the backend now
disables itself and requests complete with naettGenericError.
- CURLINFO_RESPONSE_CODE writes a long into res->code, which is an int. Eight
bytes into four, getting away with it only because the next field absorbs
the zeroes.
- curl_easy_setopt is varargs and wants a long for these options; int literals
and int variables are UB on LP64.
- naettPlatformCloseResponse called through a null function pointer when
libcurl was missing. Found by testing that path, which segfaulted.
CI needs libcurl4-openssl-dev (curl-dev on Alpine) or it would quietly keep
building without HTTPS.
SDL_GetPowerInfo on linux asks upower through dbus for power
information, which can block DrawFPS in UI/DebugOverlay.cpp and in
turn the main thread. Run SDL_GetPowerInfo on another thread
instead to avoid the issue.
It was removed during https://github.com/hrydgard/ppsspp/pull/21982
On Linux Wayland however this can be observed without:
34:25:550 Vulkan/VulkanContext.cpp:1401 I[G3D]: surfCapabilities_.current: -1x-1
34:25:550 Vulkan/VulkanContext.cpp:1406 I[G3D]: surfCapabilities_.current after clamp: -1x-1 min: 1x1 max: 32768x32768 computed: 1x1 cbdraw
Headless.cpp, NativeApp.cpp, and SDLMain.cpp each still hand-parsed a few
argv flags directly (mount/log/state/ignore/loglevel in headless and the
app, xres/yres/dpi/scale in SDL), duplicating and in some cases conflicting
with the shared CommandLineOptions parser. Consolidate all of it into
CmdLine.cpp/.h so there's a single source of truth, and drop the now-dead
remain_argc/remain_argv filtering in SDLMain.cpp since NativeInit no longer
reads argv itself.
