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.

[file_sys] robust-er IPSwitch compiler (#3911)

2026-08-30T06:10:51+00:00

this PR reworks IPS parser to be less stupid what do i mean by this? well generally give it a bit of love so it doesn't do a lot of unsound allocations also simplify the logic greatly (and use memcmp() string idiom instead of trusting the compiler so blindly...) no this doesn't mean to uber optimize IPS to handle 999 gb/s it's more so it doesn't outright crash with edge cases as the previous codebase was quite spaghetty also the major overhead is obviously the vector shenanigans and the I/O -- but thats out of scope Test that IPSwitch mods still properly work WITH ANY GAME IF THERE IS ANY REGRESSION IN SOME GAME/MOD THEN TELL ME Signed-off-by: lizzie Reviewed-on: https://git.eden-emu.dev/eden-emu/eden/pulls/3911 Reviewed-by: crueter Reviewed-by: CamilleLaVey

[core/file_sys] implement IApplicationFunctions::GetPseudoDeviceId; common PatchManager::GetNACP for base|updates (#4159)

2026-08-03T23:50:54+00:00

a bit of refactoring so there's less code duplication... probably a good idea to make it a lambda anyways maybe this is why QLauncher didn't have proper DLCs and updates? either way "GetPseudoDeviceId" is now implemented (still stubbed) with a proper hash instead of just 0 Signed-off-by: lizzie Reviewed-on: https://git.eden-emu.dev/eden-emu/eden/pulls/4159 Reviewed-by: Maufeat Reviewed-by: CamilleLaVey

[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] patches bin button + version bug fixes (#3691)

2026-03-08T23:30:10+00:00

This fixed the delete button enabled for external content (which is auto handled and the proper way to get rid of them is either by removing its folder from ext content list, or removing the file itself) by streaming patch source thru jni. Along the way stumbled upon another bug: If you have an external content update installed (say latest version for example) and you NAND install a previous update (like in silksong's hard mode update), the newest update version string would leak to the previous one. Did videos for both. Fixed both. Seems good to go.

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

2026-03-04T21:51:35+00:00

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.
