[desktop] Basic grid view implementation (#3479)

2026-02-06T18:51:01+00:00

Closes #3441 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 Signed-off-by: crueter Reviewed-on: https://git.eden-emu.dev/eden-emu/eden/pulls/3479

[desktop] Add smooth scrolling and shift scrolling to game list (#3452)

2026-02-02T18:07:12+00:00

Intercepts Qt's awful scroll wheel handling and passes it off to a continuously self-integrating animation on the scroll bar positions. Code kind of sucks right now and I think has a bit of a perf bottleneck, but that's somewhat expected in the way I implemented it. Maybe look for a better sln? QScroller? Also while I was at it I added shift scrolling. TODO: - [ ] TouchGesture? With overshoot off - [ ] Perf Signed-off-by: crueter Reviewed-on: https://git.eden-emu.dev/eden-emu/eden/pulls/3452

[macos] Fix infinite refresh loop in Game List (#3418)

2026-01-30T17:06:57+00:00

On macOS, adding paths to QFileSystemWatcher can trigger immediate 'directoryChanged' signals (likely due to FSEvent behavior or .DS_Store updates during directory access). This caused a recursive loop where PopulateAsync would trigger itself indefinitely, leading to constant UI refreshing and high CPU usage. This fix addresses the issue by: 1. Temporarily blocking QFileSystemWatcher signals while the watch list is being populated. 2. Correcting the usage of QList::mid() in the loop (passing length instead of an end index) to avoid massive path duplication. These changes are isolated to macOS using #ifdef __APPLE__ to ensure no side effects on other platforms.

[desktop, fs] main_window separation; fix Ryujinx save data link issues (#2929)

2025-11-09T17:07:38+00:00

Some genius decided to put the entire MainWindow class into main.h and main.cpp, which is not only horrific practice but also completely destroys clangd beyond repair. Please, just don't do this. (this will probably merge conflict to hell and back) Also, fixes a bunch of issues with Ryujinx save data link: - Paths with spaces would cause mklink to fail - Add support for portable directories - Symlink detection was incorrect sometimes(????) - Some other stuff I'm forgetting Furthermore, when selecting "From Eden" and attempting to save in Ryujinx, Ryujinx would destroy the link for... some reason? So to get around this we just copy the Eden data to Ryujinx then treat it like a "From Ryujinx" op Signed-off-by: crueter Reviewed-on: https://git.eden-emu.dev/eden-emu/eden/pulls/2929 Reviewed-by: Lizzie Reviewed-by: CamilleLaVey

[qt] Ryujinx save data link (#2815)

2025-10-28T02:46:47+00:00

This adds an action to the Game List context menu that lets users link save data from Eden to Ryujinx, or vice versa. Unfortunately, this isn't so simple to deal with due to the way Ryujinx's saves work. Ryujinx stores its saves in the... config directory... in `bis/user/save`. Unlike Yuzu, however, it doesn't store things by TitleID, instead it's just a bunch of directories from 000...01 to 000...0f and so on. The way it *maps* TitleID to SaveID is via `imkvdb.arc` in `bis/system/save/8000000000000000/0/` and also an identical copy in the `1` directory for... some reason. `imkvdb.arc` is handled by `FlatMapKeyValueStore` in LibHac, which, as the name implies, is a key-value storage system that `imkvdb.arc`, and seemingly `imkvdb.arc` alone, uses. The way this class is written is really weird, almost as if it's designed to accommodate more types of kvdbs... but for now we can safely assume that there aren't gonna be any other `kvdb` implementations added to HorizonNX. Regardless, the file format is ridiculously simple so I didn't actually need to do a deep dive into C# code... of which I can basically only read Avalonia. A simple `xxd` on the `imkvdb.arc` is all that's needed, and here's everything that matters: - The `IMKV` magic header (4 bytes) - 8 bytes that don't really have anything useful to us, except for a size byte (presumably a `u32`) strewn at offset `0x08` from the start of the file, which is useless to us - Then we start the `IMEN` list. I don't know what the `IM` stands for, but `IMEN` is just, well, an ENtry. Offsets shown are relative to the start of the `IMEN` header. * 4-byte `IMEN` magic header at 0x0 * 8 bytes of filler data. It contains two `0x40` bytes, but I'm not really sure what they do * TitleID (u64) at `0xC`, for example `00a0 df10 501f 0001` for Legends: Arceus (the byte order is swapped) * 0x38 bytes of filler starting at offset 0x14 * SaveID (u64) at `0x4C`, for example `0a00 0000 0000 0000` for my Legends: Arceus save * 0x38 bytes of filler starting at offset 0x54 Full example for Legends: Arceus: ``` 000001b0: 494d 454e 4000 0000 4000 0000 00a0 df10 IMEN@...@....... 000001c0: 501f 0001 0100 0000 0000 0000 0000 0000 P............... 000001d0: 0000 0000 0000 0000 0000 0000 0100 0000 ................ 000001e0: 0000 0000 0000 0000 0000 0000 0000 0000 ................ 000001f0: 0000 0000 0000 0000 0000 0000 0a00 0000 ................ 00000200: 0000 0000 0000 0000 0000 0000 0000 0000 ................ 00000210: 0000 0000 0100 0000 0000 0000 0000 0000 ................ 00000220: 0000 0000 0000 0000 0000 0000 0000 0000 ................ 00000230: 0000 0000 0000 0000 0000 0000 494d 454e ............IMEN ``` Ultimately, the size of the `IMEN` sits at 0x8C or 140 bytes. With this knowledge reading all the TitleID -> SaveID pairs is basically free, and outside of validation and stuff is like 15 lines of relevant code. Some interesting caveats, though: - There are two entries for some TitleIDs for... some reason? Ignoring the second one seems to work though. - Within each save directory, there are directories `0` and `1`... and only `0` ever seems used??? It's where Ryujinx points you to for save, so I just chose to use that. Once everything is parsed, the rest of the implementation is extremely trivial: - When the user requests a Ryujinx link, match the current program_id to the corresponding SaveID in `imkvdb` - If it doesn't exist, just error out (save data is probably nonexistent) - If it does though, give the user the option to use Eden's current save data OR Ryujinx's current save data. Old save data is deleted depending on which one you chose. Signed-off-by: crueter Reviewed-on: https://git.eden-emu.dev/eden-emu/eden/pulls/2815 Reviewed-by: Lizzie Reviewed-by: MaranBr

[core, android] Initial playtime implementation (#2535)

2025-10-17T20:47:43+00:00

So firstly, playtime code is moved to src/common and qt specific code to yuzu/utils.cpp. The dependency on ProfileManager was removed because it was working properly on Android, and I think a shared playtime is better behavior. Now, playtime is stored in a file called "playtime.bin". JNI code is from Azahar although modified by me, as well as that I added code to reset the game's playtime which was missing for some reason on there. Before this gets merged, I plan to add the ability to manually edit the database as well. Note: Code still needs a bit of cleanup.

[qt] refactor: qt_common lib (#94)

2025-09-15T15:21:18+00:00

This is part of a series of PRs made in preparation for the QML rewrite. this PR specifically moves a bunch of utility functions from main.cpp into qt_common, with the biggest benefit being that QML can reuse the exact same code through ctx passthrough. Also, QtCommon::Frontend is an abstraction layer over several previously Widgets-specific stuff like QMessageBox that gets used everywhere. The idea is that once QML is implemented, these functions can have a Quick version implemented for systems that don't work well with Widgets (sun) or for those on Plasma 6+ (reduces memory usage w/o Widgets linkage) although Quick from C++ is actually anal, but whatever. Other than that this should also just kinda reduce the size of main.cpp which is a 6000-line behemoth rn, and clangd straight up gives up with it for me (likely caused by the massive amount of headers, which this DOES reduce). In the future, I probably want to create a common strings lookup table that both Qt and QML can reference--though I'm not sure how much linguist likes that--which should give us a way to keep language consistent (use frozen-map).
