## 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).
## AI disclosure
Developed with Claude Opus 5.5 (implementation and debugging). I reviewed, tested and can

Problem
When opening a file in a BCAT directory, Eden validated the file name using the directory validation rules. As a result, valid file names containing '.' (e.g. "VSSetting_0.byaml") were incorrectly rejected.
Fix
Use VerifyNameValidFile instead of the directory validation routine when validating file names.
Test
Verified with Splatoon 2. Files such as "VSSetting_0.byaml" could not be opened before the change and now open successfully.

thanks to @chrelliott978 for the initial impl, basically clang will yell at you if you dare use wstring_codecvt<> and some other shit, and to be fair one day it will be removed because it's deprecated (but it's c++, we know it will NEVER be deprecated)
either way this makes clang shut up
untested at all

main idea is basically to manually manage the file backed storage ourselves
basically the libc will use pooled workes who will read off sync data and may or may not use mmap, this detail can vary between libcs, so id rather have one unified concept of "paged file" as opposed to relying on the libc doing what it should
the main benefit is that one doesnt need to call fwrite/fread or whatever, they can just do normal paged file ops and such
this pr has seen changes from mapped flags as well, as some OSes; particularly android, do not enjoy being told to make hugepages that are 1GB in size, especially for lower end devices.

Aimed to fix Ender Magnolia missing shader textures. Main example is Yolvan character bullets.
By using windows version of the game, dxvk lib to make it vulkan, and renderdoc, it was possible to capture bullets, and by tracking backward composition and comparing with a similar scene from eden with missing bullets, it was possible to unveil the missing functionality: conditional Phi inputs resolve for bindless handles.
By ignoring the boolean predicate register in the shader, handles for these shaders were resolving to some old value instead of proper live conditional ones.
TESTS:
-Compare Yolvan bullets
-Usual roam on main titles for regression check.

- Add NCZBLOCK (nsz -B / .xcz) reader: each read decodes only the covered blocks and re-encrypts CTR sections, no disk output.
- Allow installing solid .nsz to NAND via DecompressNCZForInstall (lazy, incremental decode with frontier, O(n) instead of O(n^2)).
- Accept BKTR updates with thousands of sections (MaxSectionCount = 0x10000).
- Wire .nsz/.xcz into loader, registered cache, scanner, and NAND install (content_manager.h), and reject solid NCZ from the game list.
- Bump the pinned zstd to 33618c8 in cpmfile.json, which includes the upstream AArch64 revert ([33618c89](33618c89e5)) for a ZSTD_decodeSequence branch optimization that could corrupt data on ARM64; without it, solid NCZ decoding on Android fails with "Data corruption detected".

This PR primarily focuses on upbringing constexpr maps for handlers.
Each time an HLE object of a service is construed, it registers it's own handlers, over and over.
Regardless of whetever it needs them at the moment or not.
Additionally we don't require to keep track of different function pointers amongst each object.
This can be done by overriding the given function instead, as opposed to having a separate
hash map for every given object.
In other words: Remove handlers (and handlers_tipc) map for every instance
then read from a static defined per-class.
- [x] Migrate all HLE functions to new `frozen::map` constexpr time finder
- [ ] Measure if this approach actually makes better codegen
Optional:
- [x] Properly gate all functions (that have versions commented next to them)
- [x] Maybe store `HandlerFnP<>` and `const char*` separately, version gating can go in a different map as well
Information such as name can be used on debug builds, but doesn't particularly help on release as one can consult an external reference (or have an annotated IPC map)
