In order to simplify things i've reverted all the rework, added a helper to identify whether a program has a parent Application and bounded it to it's proper stores. Although this is no big deal coz it doesn't have impact on emulation, it permeates to several routines, so it needs to be tested broadly.

[common] Switch to boost::unordered_flat containers (#4326)

2026-08-31T00:58:09+00:00

Replaces all instances of ankerl's unordered map/set with boost's `unordered_flat_*` classes. This uses std::hash since boost::hash is actually a lot slower. Also adds an abstraction layer in `Common` so future changes are quicker and easier. Other implementation details: - ankerl provided hash specializations for tuple and pair, so those were ported here - std::erase_if doesn't work on boost, so just used the ADL'd erase_if This should be about equal or superior performance as unordered_dense for everything except iteration.

May not be perfect but also fixes screenshots while using qlaunch - Reworked overlay display management (input and visibility) - instead of random numbers as I've previously did, I decided to add an AppletZIndex enum for better readability.

[nce, fs] tico support, fix FS bug that would nuke entire 'switch' folder (#4086)

2026-07-23T19:59:55+00:00

Contains the minimal set of functionalities to allow tico installer succeed, and tico work normally EXCEPT for game launching (which me or someone else will investigate later) First three commits are from PR 4012. The other six, kinda dizzy to explain each one. All were implemented based on tico source, switchbrew and libnx. Hopefully the commit messages will do.

[game_list] fix crash and flashing from the directory watcher (#4099)

2026-06-16T14:20:02+00:00

So the game list watcher could rebuild the content providers (CreateFactories) while the populate worker was still scanning them, and the worker would walk a torn-down RegisteredCache and segfault in OpenFileOrDirectoryConcat. Fixed by stopping and joining the worker before rebuilding. On macOS the watcher also re-armed itself every populate. Re-adding the same paths makes QFileSystemWatcher re-emit directoryChanged (the FSEvent comes in async, so the blockSignals guard misses it), so it just kept refreshing and the list flashed forever. Now it only re-arms when the watched dirs actually changed. Also null-guarded OpenFileOrDirectoryConcat so a torn-down cache cant null-deref there.

[common/logging] Simplify logging logic and fix issues when logging before system is created (#3688)

2026-03-12T17:29:15+00:00

- our logging code was bigger than spdlog itself, why???? just keep it simple - fix issues when logging before logging system is even started - removes the "initialized logging twice" issue - removes uneeded indirection in file logging - uses direct formatting instead of jumping hoopla-around the fmt::format() ressult - code duplication and dead code removal as usual I did explore dup2() but I think it's not worth the hassle I did try `fwopen()` but it's better if things are just kept as-is. there is a lot of noise because I removed a bunch of redundant files on logging and just put everything in one file now normally this wouldn't be a good idea, however consider: the complexity of logging; it's less than 500 lines... does it really need a whole subsystem?!?!?!

[android/fs] external content loader + nca/xci patches (#3596)

Foreword: WHY DON'T EVERYBODY USE ONE FOLDER FOR EACH GAME+CONTENTS? AIN'T THIS THE FORMAT GAMES COME WHEN YOU BUE THEM? DO YOU LIVE WITH ALL YOUR FRIENDS AND HAVE A 2ND HOUSE FOR ALL THE CHILDREN? Nice, i feel better now. This feat extends Maufeat's work on external content loading. It harmonically additions: "...also, if in each game folder X, you find a folder Y, and in this folder Y you detect ONLY a single game, then mount all external content for that game found in that folder Y and its subfolders." Permanent (not toggleable). External Content folders are supported equally. Also: -Reworked several routines for preserving single source of truth between android and other systems; -Fixed the annoying unknown format error for content files, by providing proper format detection.
