core: page-aware TryReadUtf8Z and unify exit/_exit handling (#57 )

Brando	48a694e509	GUI: redesign library as a cover-art grid with game management (#48 ) * GUI: redesign library as a cover-art grid with game management Replace the sidebar game list with a full-width grid of cover tiles. Cover art is loaded automatically from each game's sce_sys/icon0.png (pic0.png fallback) and decoded off the UI thread; games without art get a deterministic gradient placeholder with the title's initials. - New layout: search/scan toolbar, tile grid with hover and selection states, bottom launch bar with cover thumbnail, collapsible launch options and console panels (console auto-opens on launch) - Right-click context menu on tiles: launch, open game folder, copy path/title ID, remove from library - Removed games persist in an ExcludedGames settings list; re-adding a folder restores any removed games beneath it - Search now also matches title IDs - Fix: placeholder brushes were constructed on the scan thread, which throws in Avalonia and was silently swallowed, yielding empty scans * GUI: show full install folder size instead of eboot.bin size The library previously displayed the size of eboot.bin alone, which wildly understates a game's real footprint. The install folder is now totaled recursively in the existing background pass (after cover art, which is cheaper and more visible), and each tile updates live once its size is ready. * GUI: selection backdrop, smaller tiles, controller navigation Address review feedback on the library redesign: - Selecting a game fades its key art (sce_sys/pic0.png, pic1.png fallback) in as the window backdrop, dimmed by a gradient scrim; decoded off the UI thread and cached per entry - Cover tiles reduced from 156px to 128px - The library can be driven with a DualSense: d-pad/left stick moves the selection (hold-to-repeat, row-aware), Cross launches, Circle stops; input is ignored while the launcher window is unfocused. Reuses the pad HID reader by compile-linking its dependency-free sources instead of referencing all of SharpEmu.Libs	2026-07-11 13:17:10 +03:00
Brando	165927882b	Pad: native DualSense support via raw HID (#52 ) * Pad: native DualSense support via raw HID Read a real DualSense (or DualSense Edge) controller directly over Win32 HID and feed its state into scePadRead/scePadReadState, replacing the keyboard-only input path. No new dependencies. - Device discovery by Sony VID/PID through setupapi/hid.dll, with hot-plug: disconnects fall back to keyboard and reconnect automatically - USB input report 0x01 and Bluetooth extended report 0x31 (activated via the feature report 0x05 handshake) are both parsed - Full mapping to SCE_PAD_BUTTON conventions: face buttons, d-pad hat, L1/R1/L2/R2 digital bits, analog triggers, L3/R3, Options, touchpad click, both sticks - Controller and keyboard input merge: buttons OR together, controller sticks win past a small deadzone, triggers take the max * Pad: rumble and lightbar output for DualSense Wire scePadSetVibration, scePadSetLightBar and scePadResetLightBar to real DualSense output reports. The output payload follows the same layout as the Linux hid-playstation driver: both rumble motors, lightbar RGB and the player LED indicator. - USB uses output report 0x02; Bluetooth uses the 0x31 wrapper with a sequence tag and CRC32 (0xA2-seeded) trailer, transport detected from the first input report - Output goes through a dedicated device handle so writes never contend with the blocking input read loop - On connect the controller gets a default state (blue lightbar, player 1 LED); rumble state resets on disconnect Verified on hardware over USB: lightbar color cycling and both motors. Bluetooth output is implemented per spec but not yet hardware-tested.	2026-07-11 11:54:38 +03:00
