Modern Big Picture Mode

A second "Modern" Big Picture Mode layout inspired by streaming services is now available, selectable from Settings:

• Hero Spotlight — Large artwork, game title, system badge, star rating, play stats, and launch buttons at the top.
• Horizontal Carousel Rows — Scroll through Recently Played, Favorites, Top Rated, Most Played, All Games, and per-system rows.
• Card hover effects, right-click context menu (Launch, Favorite, Rate, ROM Info, Artwork, Open File Location, Copy Path), and mouse-wheel horizontal scrolling.
• Sort by Play Count option added to both Classic and Modern views.
• Full gamepad, keyboard, search, filter, screensaver, gallery, and Discord Rich Presence support.

First-Run Guided Tour

A 13-step animated onboarding tour now runs on first launch, walking you through every feature of the app:

• Covers ROM Browser, Patching, Analysis, Headers, Utilities, Emulator Integrations, Big Picture Mode, and Settings.
• Step indicator dots, Back/Next/Skip navigation, and smooth animated transitions.
• Can be restarted anytime from Settings.
• Keyboard navigation supported (Enter/Right to advance, Left to go back, Escape to skip).

Emulator Configurators

Three powerful new configurators let you edit emulator settings directly inside RetroMultiTools — no need to open each emulator separately:

• RetroArch Configurator — Edit retroarch.cfg with a 10-tab UI covering 355+ settings (Paths, Video, Audio, Input, Core/Saving, Menu, Network, Frame Throttle, Achievements, Misc). Includes search/filter, 3 additional tabs, and expanded settings coverage (175→355).
• MAME Configurator — Edit mame.ini with a 6-tab UI for 170+ settings (Paths, Video, Sound, Input, Performance, Misc). Includes per-window multi-monitor options and search/filter.
• Mednafen Configurator — Edit mednafen.cfg with an 8-tab UI covering all 22 emulation modules (General, Video, Sound, Input, Paths, Per-System, Netplay, Advanced). Includes search/filter.

All three support: auto-detection of config files (including Flatpak/Snap installs), unsaved changes warnings ("dirty state" tracking), save/save-as, reset to defaults, and create new config.

Packaging & Distribution

• Linux: AppImage, Snap, Flatpak, DEB, RPM, APK (Alpine Linux), and Pacman (.pkg.tar.zst) packages are now built automatically.
• macOS: DMG drag-and-drop installer added alongside PKG and ZIP.
• FreeBSD: New build workflow and installation guide added.

Documentation & Website

• GitHub Pages documentation site with dark theme matching the app's color scheme.
• Comprehensive install instructions for all Linux distributions supported by .NET 8.
• New feature documentation for Disc Tools and USB Tools.
• README overhauled and compacted with download tables for all package formats.

Updates & Improvements

User Interface

• Sidebar navigation replaced from a flat list with a collapsible TreeView, making it easier to find tools by category.
• Sidebar search added — quickly filter and jump to any tool by typing its name.
• Drag-and-drop file input added across 11 tool views — drop ROM files or images directly onto input fields.
• Keyboard shortcuts added throughout the app for common actions.
• Tooltips added to all action buttons and toolbar items for better discoverability.
• Progress indicators added where previously missing.
• ROM Browser context menu improved with organized submenus, direct tool navigation, and new actions (Open File Location, Copy File Path).

Builds

• Removed non-self-contained builds — all releases are now self-contained (no .NET runtime required).
• Maximized compression across all builds for smaller downloads.

Bug Fixes

Auto-Updater

• Fixed the updater not detecting new releases when GitHub's "latest" endpoint didn't return the newest version. Now scans all recent releases and picks the highest version.
• Fixed network errors being silently swallowed, making them indistinguishable from "no update available."
• Fixed large update downloads timing out due to an overly aggressive 30-second limit on the entire download.
• Fixed temporary update files never being cleaned up after installation.
• Fixed UI buttons not resetting properly after cancelling a download.
• Fixed version comparison bugs where tags like v4.0 didn't compare correctly with v4.0.0.
• Fixed stale update state remaining after a failed check, leaving the UI inconsistent on retry.

Security

• Path traversal vulnerabilities fixed — file operations now validate paths to prevent escaping intended directories.
• Credential validation added where previously missing.
• Fixed socket resource leak in Discord Rich Presence when connection fails.

Emulator Integration

• Fixed macOS .app bundle detection selecting the wrong application when multiple apps existed in the same folder.
• Fixed Discord Rich Presence not being set when launching a game from Big Picture Mode.
• Fixed Mednafen launcher missing Flatpak detection paths (RetroArch and MAME already had them).

Stability & Reliability

• Fixed process deadlocks that could freeze the app when running external tools.
• Fixed race conditions in concurrent operations.
• Fixed several null reference crashes across ROM info display, gallery navigation, and artwork viewing.
• Fixed missing exception handling in settings loading that caused crashes in sandboxed environments (Flatpak, Snap).
• Fixed URL opening (links, download pages) failing inside Flatpak sandboxes — now uses xdg-open on Linux.
• Fixed CUE file path handling returning invalid paths in certain scenarios.

User Interface Fixes

• Fixed view layouts stretching incorrectly and not resizing properly.
• Fixed radio button options reading stale values from sibling buttons, causing wrong settings to be applied.
• Fixed format dropdown resetting unexpectedly when switching between views.
• Fixed button states not updating correctly (buttons staying disabled or enabled at wrong times) across 9 views.
• Fixed sidebar items getting clipped and scrollbar overlaying content in the TreeView (still not perfect but better).
• Fixed mode switching not working in several tool views.
• Fixed hardcoded English strings that weren't going through the translation system.

Big Picture Mode

• Fixed screensaver activating during gallery slideshow mode.
• Fixed search box swallowing normal keyboard input.

Packaging

• Fixed Linux DEB package missing runtime dependency declarations.
• Fixed Inno Setup (Windows installer) not offering a desktop shortcut option.

Retro Multi Tools v4.1.0

Changelog v4.0.0 -> v4.1.0

Updates & Improvements

Better Emulator Detection Across All Platforms

• More install locations are now recognized — RetroArch, MAME, and Mednafen are now automatically found in additional common locations on Linux (e.g. Debian/Ubuntu system paths), macOS (including MacPorts), and Windows (Chocolatey).
• Nix package manager support — Emulators installed via Nix on Linux and macOS are now automatically detected.
• MAME Flatpak support — MAME installed as a Flatpak (user or system-wide) is now detected and can be launched directly, matching the existing RetroArch Flatpak support.
• ARM64 Linux core discovery — RetroArch cores on ARM64 Linux systems are now found automatically.

Improved macOS Application Handling

• Smarter .app bundle recognition — Selecting an emulator application on macOS now works reliably, even if the app has an unusual name or internal structure. The app reads the bundle's metadata to find the correct executable.
• Browse button now works for .app bundles — On macOS, the Browse button in settings uses a folder picker so you can properly select .app applications. You can also paste a path directly into the text field and press Enter.
• Selecting a parent folder works too — If you select a folder like /Applications/ instead of the app itself, the tool will automatically find the emulator app inside it.
• Native menu bar now visible on macOS — The application menu bar now appears correctly in the macOS menu bar at the top of the screen.

Other Improvements

• Improved network connection handling — Downloads for RetroArch cores and controller profiles now use a more efficient and consistent connection method.
• Custom install path support — If you point the tool to a custom emulator folder (e.g. /opt/custom/retroarch/), it will now correctly find the executable inside, including in bin/ subdirectories.
• RetroArch core search follows the executable — Cores are now found relative to wherever your RetroArch executable is installed, not just in hardcoded system paths.

Bug Fixes

Crash Fixes

• Fixed crash when changing language on macOS and Linux — Switching the app language in Settings no longer crashes the application. The language change is now applied safely in the background.

Emulator Detection & Launching

• Fixed emulators not being found on fresh installs — On a first-time setup where config directories don't exist yet, RetroArch and Mednafen are now detected properly instead of silently failing.
• Fixed custom emulator paths being ignored — Setting a custom path to an emulator folder (instead of the exact executable file) now works correctly on all platforms.
• Fixed macOS apps with different letter casing not being recognized — An app named retroarch vs. RetroArch inside the bundle no longer causes detection to fail.
• Fixed selecting files from inside a .app bundle — If the file picker navigated inside a macOS .app bundle and you selected an internal file, it was previously rejected. This now works correctly.
• Fixed .app bundles in paths with spaces not being detected — Paths like /Users/name/My Games/RetroArch.app now work correctly.
• Fixed Browse button doing nothing on macOS — Selecting a .app application via the Browse button previously returned empty results silently. This is now resolved.

Controller Profiles & Shortcuts

• Fixed controller profile downloads failing on system-installed RetroArch (Linux) — Downloads now save to the user config directory when the system install location isn't writable.
• Fixed Linux desktop shortcuts with special characters — Shortcut arguments containing spaces or special characters are now properly escaped, preventing launch failures.

UI & Localization

• Fixed MAME and Mednafen settings buttons using wrong labels — The Browse, Auto-Detect, and Clear buttons in MAME and Mednafen settings now show their own correct labels instead of RetroArch-specific ones.
• Fixed broken placeholder in Italian translation — A garbled text placeholder in the Italian core-not-found message has been corrected.

Retro Multi Tools v4.0

Retro Multi Tools v4

New Features

Gamepad Key Mapper Utility

A new utility for mapping gamepad buttons, sticks, and triggers to keyboard keys, mouse buttons/movement, scripts, and multi-step macros. Includes switchable mapping profiles, auto-profile switching based on the active window, profile import/export, and cross-platform input simulation (Windows, Linux, macOS).

Mednafen Emulator Integration

Full launcher support for the Mednafen emulator — on par with RetroArch and MAME. Supports 13 systems (NES, SNES, Game Boy, GBA, Genesis, Saturn, PC Engine, and more). Includes cross-platform auto-detection, a settings UI for browsing/configuring the Mednafen path, and launch buttons in both the ROM Browser and Big Picture Mode.

Unified Archive Manager

The separate ZIP Extractor and GZip Decompressor have been merged into a single Archive Manager. It now supports extracting ZIP, RAR, and 7z archives, plus creating ZIP archives from ROM files (single file, batch one-per-ROM, or all-in-one).

xDelta / VCDIFF ROM Patching

The ROM Patcher now supports xDelta and VCDIFF patch formats in addition to the existing IPS and BPS formats. This implements a full VCDIFF (RFC 3284) decoder with all instruction types and checksum verification.

Quick System Cycle

Use [ and ] keys (or gamepad triggers) to cycle through the system filter forward/backward with wrap-around, with a brief indicator showing the selected system.

Gallery / Auto-Scroll Mode

Automatically advances through the game card grid every 3 seconds. Wraps at the end. Stops on any manual navigation or when another overlay opens.

Play Time Tracking

Automatically records how long you play each game (wall-clock time from process start to exit). Displayed in the detail panel, ROM Info overlay, and Collection Statistics. Formatted as human-readable (e.g. "2h 15m").

Fullscreen Artwork Viewer

Press V to open a fullscreen overlay cycling through box art, screenshots, and title screens at full size. Navigate with arrow keys or gamepad.

User Game Ratings

Rate games from 1 to 5 stars using number keys or a gamepad action. Ratings appear on game cards and the detail panel. A new "Sort by Rating" option is available.

Updates & Improvements

• Fixed the settings save failing silently on sandboxed platforms (macOS, Snap, Flatpak).
• Fixed temporary file leaks in the gamepad mapping storage.

Retro Multi Tools v3.0

Retro Multi Tools v3

New Features

• Neo Geo Support via Geolith Core

  • Neo Geo ROMs are now launched through the geolith core in RetroArch, which provides much more accurate emulation for both AES (home console) and MVS (arcade) hardware.
  • A BIOS mode notice is shown in the status bar and in the Big Picture view whenever a Neo Geo ROM is selected or launched.

• ZIP ROM Detection

  • The app can now look inside ZIP files to detect which gaming system the ROM belongs to (e.g., a zipped NES ROM is recognized as NES, a zipped arcade set as MAME). Previously, ZIP files were completely invisible to the scanner and organizer.

• MAME Support for Arcade ROMs

  • Arcade ROMs can now be launched directly with MAME from both the ROM Browser and the Big Picture Mode.
  • The "Launch with MAME" button and context menu option are only shown/enabled when an Arcade ROM is selected.

• CHD Converter & MAME DAT Editor

  • New tools added: a CHD Compressor/Decompressor for converting disc-based game images, and a MAME DAT Editor for viewing and editing MAME game database files.

• RetroArch Utilities

  • Added several new RetroArch-related tools:
    • Achievements Writer — manage RetroAchievements data for games
    • Playlist Creator — build RetroArch playlists from your ROM folders
    • Shortcut Creator — create desktop/OS shortcuts to launch ROMs directly in RetroArch
    • Integration View — a dedicated area for all RetroArch settings and tools

• MAME Integration View

  • MAME now has its own dedicated Integration page (just like RetroArch), where you can browse, auto-detect, download, or clear the MAME executable path.
    • The general Settings page has been cleaned up — emulator-specific settings are now found in their respective Integration views.

• New Accessible Settings

  • Two previously hidden settings are now accessible from the Settings page:
    • Big Picture Card Scale — adjust the size of game cards in Big Picture mode (0.5× to 2.0×)
    • Gamepad — enable/disable gamepad support and configure the dead-zone sensitivity

• ROM Organizer — Copy or Move Choice

  • When organizing ROMs from the ROM Browser, you are now asked whether you want to Copy or Move the files, instead of always copying.

Analogue Pocket SD Card Tools

• Library Image Generator

  • Automatically generates placeholder cover images for any ROMs in your library that don't already have one. Images are saved directly to the Pocket's library folder.

Analogue NT & Super NT SD Card Tools

• Custom Font Generator
  • Generate a custom menu font for your console:
    • Use the built-in default font — no extra files needed.
    • Or provide your own 128×128 BMP image containing a 16×16 grid of 8×8 characters to generate a fully custom font.
    • Works for both the Analogue NT and the Super NT (selectable via radio buttons).
• NES Header Repair
  • Select any .nes ROM file and repair its iNES header by cleaning invalid padding bytes. NES 2.0 headers are automatically detected and left untouched.

Analogue Mega SG SD Card Tools

• Custom Font Generator

  • Same font generation capability as for the NT/Super NT — generate a default font or create one from a custom 128×128 BMP image, saved directly to your Mega SG's SD card.

• Save File Converter (Saves-Manager)

  • Load any save file (.sav, .srm, .eep, etc.) and convert it between different formats. The app shows the file size and detected type before converting. Available conversions:

Conversion	What it does
Swap Endian (16-bit)	Reverses byte pairs
Swap Endian (32-bit)	Reverses 4-byte groups
Pad to Power of Two	Pads the file to the next power-of-two size
Trim Trailing Zeros	Removes trailing 0x00 bytes

Analogue 3D (N64) SD Card Tools

• Scan Game Paks

  • Scan your SD card for N64 Game Pak ROMs (.z64, .n64, .v64). Each game entry shows:
    • The game's internal name and game code (read from the ROM header)
    • File size
    • Icons indicating whether it already has label artwork, display settings, or hardware settings

• Per-Game Display Settings

  • Click any game in the list to edit its individual display settings:
    • Resolution (auto, 240p, 480i, 480p, 720p, 1080p)
    • Aspect Ratio (auto, 4:3, 16:9)
    • Smoothing (off, bilinear, crt)
    • Crop Overscan (on/off)

Settings are saved as JSON files directly on the SD card.

• Per-Game Hardware Settings

  • Also editable per game:
    • Expansion Pak (on/off)
    • Rumble Pak (on/off)
    • CPU Overclock (on/off)
    • Controller Pak mode (auto, memory, rumble, none)

• Set Label Artwork

  • After selecting a game from the list, you can assign a custom PNG image as the label artwork for that game. It is saved to the SD card's library images folder.

Updates & Improvements

• Emulator Config Generator Improvements

  • The config generator now automatically creates any missing output folders, preventing errors when saving to new locations.
  • Several internal improvements to keep generated config files clean and consistent.

• Settings & UI Cleanup

  • RetroArch and MAME configuration options removed from the general Settings page — they are now exclusively in their dedicated Integration views, making Settings less cluttered.

• Project Structure Reorganization

  • All gaming system names are now sorted A-Z throughout the app — dropdowns, lists, and documentation all follow alphabetical order.
  • Internal code organization improved.

Bug Fixes

• macOS: RetroArch could not be selected in Settings

  • On macOS, the file picker was unable to find or select the RetroArch.app bundle. This is now fixed — the file picker correctly recognizes .app bundles on macOS.

• RetroArch Core Downloader: ARM64 Support Missing

  • The Core Downloader always downloaded x86_64 cores on Linux, even on ARM64 devices (e.g., Raspberry Pi, Apple Silicon). It now correctly detects and downloads the right architecture.

• Emulator Config Generator: Several Silent Failures

  • Mesen: The save state directory setting was silently dropped and never written to the config file.
  • Mednafen: The "Show FPS" setting was mapped to the wrong config key and had no effect.
  • RetroArch: The integer scaling setting was omitted when disabled, meaning old config files could retain a stale "enabled" value.

• ROM Detection: False Positives for Common File Types

  • Files like Markdown documents (.md), generic binaries (.bin), and random ZIPs were incorrectly identified as game ROMs. Detection now validates file contents to confirm system identity.

• ROM Detection: Wrong File Size & Truncated Saturn Titles

  • Several system parsers reported an incorrect file size for ROM info. This is now fixed to show the actual file size.
  • Sega Saturn ROM titles were cut off at 16 characters; the correct limit of 112 characters is now used.

• BPS Patcher: Data Corruption When Patching ROMs

  • A bug in the BPS patch engine could cause incorrect data to be written when patching large ROMs, resulting in a corrupted output file. This is now fixed.

• Save File Converter: Edge Case Producing Incorrect Output

  • When trimming padding from a save file where all bytes were padding, the converter returned a 1-byte garbage result instead of an empty file.

• Discord Rich Presence: Connection Could Leak Resources

  • If the Discord connection failed after partially connecting, system resources (named pipe handles) were not properly released. This is now handled correctly.

• Gamepad: Controller Stopped Working After Closing Mapper Window

  • After closing the Gamepad Mapper window, the gamepad service was not restarted, causing controllers to stop responding until the app was restarted.

• General Stability & Error Handling

  • Fixed a potential crash when ROM detection received an empty file path.
  • Fixed a potential crash in the app's crash reporter itself.
  • Fixed a rare crash when copying text to the clipboard on Linux (Wayland) without windo...

• Updated Cloud Storage Support for sending ROMs

  • Now also supports Google Drive, Dropbox & OneDrive

• Updated MAME Arcade Rebuilder & Auditor

  • The MAME Arcade Rebuilder had no way to choose between split, merged, or non-merged rebuild modes & Auditors only searched top-level directories
  • Added :
    • Split: only non-merged ROMs per machine (existing default behavior)
    • NonMerged: includes all ROMs ignoring merge attribute — each ZIP is self-contained
    • Merged: builds only parent ZIPs, aggregating unique clone ROMs via name-based deduplication
  • Added recursive directory search options in Rebuilder & Auditor

• Updated Duplicate Finder

  • Added 'Delete Duplicates' option that deletes all copies except the first in each group, with per-file error handling and progress reporting
    • Two-step confirmation: shows file count and estimated space savings before committing
    • Post-deletion summary with freed bytes

• Dump Verifier Improvements

  • Added header validation checks for 7 more systems:
    • SMS/Game Gear: TMR SEGA header checksum validation
    • Atari 7800: ATARI7800 signature check
    • Atari Lynx: LYNX header presence check
    • Sega 32X: SEGA identifier check
    • MSX: AB cartridge signature check
    • Virtual Boy: Title presence check
    • PC Engine: Copier header warning

• Security Analyzer Improvements

  • Added checksum/header protection reporting for 4 more systems:
    • Sega 32X internal checksum
    • Virtual Boy header integrity
    • Atari Lynx LYNX header
    • Atari 7800 ATARI7800 signature

Fixes

• Application Icon fixed on Linux & macOS

• Critical ROM-Breaking bugs fixed in the "Header Fixer" utility

  • N64 CRC algorithm — The CIC-NUS-6102 checksum was fundamentally broken: it was missing the critical rotate-left (ROL) operation on each data word, had wrong variable assignments in the accumulator loop, and produced incorrect final CRC values from wrong XOR combinations. Any ROM "fixed" by this code would have had its CRC corrupted.
  • ColecoVision — Bytes 0x0A–0x0F were being zeroed as "reserved", but these are RST interrupt vectors (RST 10h, RST 18h, RST 20h). Games that used these interrupts would crash after being "fixed". Now the fixer is validation-only since the ColecoVision header has no reserved bytes to clean.
  • Atari Lynx — Bytes 10–63 were being zeroed, destroying the cart name (bytes 10–41), manufacturer name (42–57), and rotation flag (58). Now only the actual spare bytes 59–63 are cleaned.
  • Intellivision — Bytes 0x08–0x0F were being zeroed, but these contain program segment data in Intellivision ROMs (which use 16-bit words with variable header layouts). Now validation-only.
  • NES — Bytes 8–15 were all being zeroed, which destroyed valid iNES 1.0 data: PRG-RAM size (byte 8), TV system/PAL flag (byte 9), and additional flags (byte 10). Now only the true zero-padding bytes 11–15 are cleaned.
  • SNES checksum — Didn't handle non-power-of-2 ROM sizes (3 MB, 6 MB, 1.5 MB). The SNES hardware mirrors the excess portion to fill the next power-of-2 boundary, and the checksum must account for this mirroring. Games like Tales of Phantasia and Star Ocean (6 MB) would get incorrect checksums.
  • Neo Geo Pocket — Was zeroing bytes 0x30-0x3F which are executable ROM code, not reserved bytes. The NGP header is only 48 bytes (0x00-0x2F); the actual reserved area is 0x24-0x2F. Now only zeroes the real reserved bytes, preserving all program code.
  • PC Engine / TurboGrafx-16 — Was zeroing the 512-byte copier header in place, leaving a ROM with 512 null bytes still prepended. Emulators detect the copier header by file size (size % 8192 == 512), so they'd still try to parse it but find invalid/null data. Now properly strips the copier header entirely, producing a clean ROM.
  • Atari Jaguar — Was zeroing bytes 0x440-0x47F which contain GPU/DSP initialization code and boot stub data. There are no well-defined reserved bytes in this area. Changed to validation-only.
  • Watara Supervision — Was zeroing bytes 0x10-0x1F without documented justification. The Supervision header format is poorly documented and these bytes may contain bank-switching configuration or other functional data. Changed to validation-only.
