loader: read a loose dump's display version from its own files

2026-10-30T20:41:32+00:00

Mario Kart World 1.8.0 reported 1.0.0: GetDisplayVersion only knew installed titles' metadata, and a loose ExeFS/RomFS dump has none. The dump's version now comes from its control.nacp (in ExeFS, or up to three directories above it), else from RomFS System/Resource/ResourceSizeTable.Product.NNN (Mario Kart World has no NACP; Product.180 is 1.8.0). Folder names are never parsed.

loader: load a loose ExeFS when given its main

2026-10-27T16:00:22+00:00

'main' is also a valid NSO, so IdentifyFile picked the single-NSO loader, which skips main.npdm, rtld and the sdk modules and then crashes writing into an uninitialised process. Prefer the ExeFS directory loader when the file is named main and sits in an ExeFS.

[core] Support block-compressed NSZ and XCZ (#4552)

NCZ format and CTR counter semantics follow the reference nsz tool and its Rust port: - https://github.com/nicoboss/nsz (Decompressor.py, BlockDecompressorReader.py) - https://docs.rs/nsz-rs/0.3.0/src/nsz_rs/decompress.rs.html The last-block edge case (decompressed size is an exact multiple of block size) is handled as described in https://github.com/nicoboss/nsz/issues/210 Reviewed-on: https://git.eden-emu.dev/eden-emu/eden/pulls/4552 Reviewed-by: CamilleLaVey Reviewed-by: Shinmegumi

[core, hle, video_core, memory] Improve multi-process, display layers, dynamic shader cache and rework overlay (#4238)

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. Also split capability of input by touch and gamepad. - etc. Reviewed-on: https://git.eden-emu.dev/eden-emu/eden/pulls/4238 Reviewed-by: Samuel Reviewed-by: CamilleLaVey Reviewed-by: MaranBr

[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)

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.
