## Summary
Automatic controller assignment for Eden, aimed at couch co-op and handheld PCs (Steam Deck,
Legion Go, ROG Ally, AYN Odin), plus a set of fixes for running Eden in Steam's Game Mode
(gamescope) and under Steam Input.
## Controller Assignment Handler
Settings > Controls gains a **Controllers** tab. The handler is a segmented choice:
| Handler | Behaviour |
|---|---|
| **Modern Console** | Automatic: each controller that connects becomes the next player (up to 8). |
| **Manual** (default) | Players are set in each player's tab, as before. Its Controller Applet choice: **Disabled**, **Custom Frontend** or **Real Hardware** (the console's own applet, LLE). |
Under Modern Console, **Portable Handheld Gaming Device with Built-in Controller** (on/off)
makes external controllers take the players first, with the handheld's own controls used only
when none is connected.
In the automatic modes:
- Players follow their controllers across reconnects: a controller that leaves keeps its player
for 45 seconds and takes it back when it returns. Each controller keeps its own mappings when
it changes player, for the session.
- At most eight players; a ninth controller waits until a player is free.
- The user's saved controller setup is never rewritten; remaps made in the Controls tab last for
the session, and input profiles are what persist.
- Input profiles can be picked or removed per player, from the Controllers tab or each player tab.
- A controller whose player has no controller mappings (a fresh setup) gets its default mapping.
A DSU (cemuhook) motion binding from the manual setup is kept, for handhelds whose own gyro
needs it.
## Gameplay options
- **Pause When a Controller Disconnects** (on by default): the game pauses when a player's
controller is turned off, or has been gone for 3 seconds, and resumes when a controller takes
that player again. Pressing + on another controller goes on without it.
- **Use Any Controller as Joy-Cons**: a game that only takes Joy-Cons gets them automatically
(dual, or a single sideways one with the buttons arranged to fit).
- **Button Layout**: By Position or By Label, for Xbox and PlayStation style controllers.
- **Player Lights**: controllers that have them show their player number.
## Controllers tab and player tabs
- Connected Players: each player with its controller and battery, profile picker, Swap, Config,
Turn Off (Bluetooth), reorder arrows, drag to swap, and click to rumble. Controllers can be
given a name for the session.
- Assign Handheld Controller: auto-detect, or pick/Identify the handheld's own pad.
- P1-P8 tabs show each player's battery and can be dragged or moved with arrows to change the
player order.
- In Modern Console the Controllers and player tabs use a modern card layout that follows the
light and dark themes, including the system's dark mode (macOS).
## On-screen display
- **Controller Overlay** (View menu, Ctrl+Shift+V): players, their controllers and batteries,
and each player's recent buttons, including stick moves (LS/RS) and clicks (L3/R3). How many
inputs are kept and for how long can be set.
- **Controller Hints**: names a controller in the bottom-left corner when it joins or leaves
a player, and says when the game pauses for a disconnected one. Works without the overlay.
Both are drawn into the presented frame as crisp overlay panels (not scaled with the game, not
in screenshots), so they show inside gamescope.
## Steam Input and gamescope fixes
- **Native gyro under Steam Input.** Steam's virtual pads carry no motion sensors. Eden now opens
the real motion-capable controller behind each virtual pad for its sensors only (Steam Deck,
Steam Controller incl. the 2026 model, Sony, Nintendo), and turns on the Deck's IMU, which
Steam keeps off unless the layout uses the gyro. No DSU server or Steam layout change needed.
- **Bypass Steam Input** (Controllers tab, shown when launched through Steam): Eden opens the
real controllers itself instead of Steam's virtual pads.
- **Controller identity under Steam.** All virtual pads share one GUID and Steam moves physical
controllers between them; controllers are tracked by their Steam handle and slot instead.
- **Handheld detection under Steam.** The Deck's own controls are recognised behind Steam Input
without mistaking standalone controllers (e.g. the Steam Controller) for them.
- **Windows no longer rescale on hover in Game Mode.** gamescope scales a window to fit the
screen together with any tooltip reaching past it, so the main window and Settings grew and
shrank on hover. Under gamescope they now fill the screen.
- **VSync modes in Game Mode.** gamescope offers only some present modes, so Immediate and FIFO
Relaxed vanished silently. They are now listed greyed out with a tooltip pointing to Steam's
Disable Frame Limit and Allow Tearing settings.
- **Stick range testers on small screens.** The controller drawing scales down to fit on
800-pixel screens instead of cutting off the stick range circles.
- **Midnight Blue themes.** A hovered menu-bar item is readable again, and hovered tabs no longer
change size (which made the Settings tabs shake).
## Fixes
- Crash when HID received a controller update before NPad's applet resource was set up.
## Testing
Tested on a Steam Deck (Desktop and Game Mode, direct and Steam launches) with Xbox
controllers, plus a stress test with up to 10 virtual controllers connecting, disconnecting and
pressing at random in both automatic modes (no assignment errors, never more than 8 players,
disconnect pauses resume as expected).

Very self-explanatory; implementation of the feature for post-processing shaders for Android (at least for now); will allow users to enhance the graphic quality of video games based on the use of multiple shaders adjustable, presets and more, inspired on the PPSSPP implementation, this feature adds 22 customizable shaders (1 pass) that lives on the overlay of the screen, which means that aside of the capability to chain multiple shaders on the screen, this doesn't have depths (pixel/ depth z-buffer) so it ensures the performance with it's use. Few shaders were a faithful port from PPSSPP with their respective attribution on the shader headers for their respective owners; and there are adaptations from public references/ cinematographic (Anime4K) and the rest are my own addition.
_Special Credits:_
1.- PPSSPP Team for their contribution on the public references for shaders: Henrik Rydgard, ShadX, SimoneT, KillaMaaki and guest(r).
2.- Niklas Haas.

we have no use for it
it's dead code
most of the time users just complain about how the list isn't updated
ok so what if we update it? great now its more noise added to the git, awesome
even if we constantly update it, we introduce new breakage that makes keeping
track of things extremely difficult
either we integrate with emuready (would violate self containment principles)
or we integrate with emuready in a similar fashion to eden news outlet
(where we cache the list with some TTL of like 60 mins or whatever)
that would be better respecting of "self containment" but would probably
require having a quick way to update the list additively, probably filtered to the user's
device instead of a global thing, and i dont think emuready has that granularity
nor we have the "connect this to that" for the api stuffs
another (which is what i propose here) is throw everything out of the window
until someone can come up with something better

Adds a basic carousel view, or essentially a horizontal list a la Android/Qt Quick.
Lacks a lot of niceties like autoscroll, smooth shifts, etc. Will work on those later
Also fixed a bug introduced recently that capped game icon size to 8 at the low end, breaking the None option

- Move Game Icon Size to the main toolbar. It's cleaner that way
- Add a "Show Game Name" toggle that does as it says. Disabling it
basically creates an "icons-only" mode. Useful for controller-only
nav with big icons (TODO: maybe make a 192 size?)
- Fixed a crash with controller nav. Oops
- Rounded corners of the game icon in grid mode
- Fixed the scroll bar creating extra clamping range on the grid icons
- Item can be deselected if user clicks on the blank space outside of the view
As a bonus fixed a crash on mod manager
Future TODOs for design:
- [ ] Row 1 type. Not sure what to do here tbh.
- [ ] Move around game list settings in configure_ui to make it clear
that nothing there affects the grid view.
- [ ] 192x192 size? 256 feels too big on my 1440p screen whereas 128
feels too small.
- Set text space as a function of fontMetrics.

Basic impl of a grid view on the game list. The ideal solution here
would be to use QSortFilterProxyModel and abstract the game list model
out to a QStandardItemModel, but that is too much effort for me rn.
Adapted the "card" design from QML, can 1000% be improved but QPainter
is just such a pain to deal with. Implanting a Qt Quick scene into there
would legitimately be easier.
Anyways, margins and text sizes lgtm at all sizes, though please give
feedback on both that and the general card design.
Future TODOs:
- [ ] Auto size mode
- [ ] Refactor to use models

Adds fully functional overlay display.
- Enable Overlay Applet via "View" -> "Enable Overlay Display Applet"
- Open the overlay by pressing the home button for over 1s
- Can adjust volume
- Can toggle airplane mode (if on WiFi, maybe if overlay is enabled pretend to be on WiFi?)
- Future TODO(?): Adjust Brightness implementation for host system
- Inputs are properly registered. e.g. if overlay open, application does not register inputs.
You can control volume and airplane mode outside of the emulator window

Adds a menu option to install firmware from a packed ZIP.
This PR additionally lays the groundwork to add data import/export via ZIP. In the future, a qt_common subproject should be added to handle common Qt tasks such as this.
Furthermore, to decrease dependency complexity, this also introduces CPM, a wrapper around FetchContent. In theory, this should also lay the groundwork for #8 as well.
