Odin est un émulateur open source des cartes d’arcade Sega Hikaru et Gaelco ATV Track, développé par Réda Chérif-Touil (Tovarichtch), également impliqué dans le développement de PCSX2x6 et de Xbox-Chihiro, ainsi que développeur du build MAME (Konami M2 Edition). Il s’agit d’un fork conséquent de Valkyrie, l’émulateur Hikaru initialement développé par Stefano Teso entre 2011 et 2013.
L’émulateur repose sur une approche d’émulation de bas niveau (LLE), qui consiste à reproduire le fonctionnement des composants matériels en exécutant les programmes des véritables puces lorsque leur fonctionnement est connu. Sur Gaelco ATV Track, cette approche concerne également le cœur microcodé du processeur Neon 250, qui exécute son propre code, tandis que le rendu 3D est généré à partir de la scène qu’il construit. Le rendu graphique est assuré par OpenGL ou Vulkan.
Odin prend actuellement en charge les six jeux de la plateforme Hikaru, avec deux titres disponibles dans leurs versions originales et révisées: Air Trix, Brave Firefighters, Planet Harriers, NASCAR Arcade, Star Wars Racer Arcade et Cyber Troopers Virtual-On Force. Il émule également plusieurs jeux du système Gaelco ATV Track: ATV Track, Gaelco Football et Smashing Drive, ce dernier étant disponible en plusieurs versions régionales.
L’émulateur propose notamment la gestion des manettes, la prise en charge des volants avec retour de force pour certains jeux, ainsi que des pistolets optiques pour Brave Firefighters. Il permet également la sauvegarde des données de Virtual-On Force sur carte virtuelle et la possibilité de relier plusieurs bornes via le réseau. Les sorties des bornes peuvent aussi être transmises, suivant un principe similaire à celui utilisé par MAME.
Une interface graphique basée sur Dear ImGui est intégrée au projet. Les illustrations des écrans-titres et les éléments graphiques des bornes sont proposés séparément dans une archive dédiée.

Citron-Nextendo est un fork de l’émulateur Nintendo Switch Citron, lui-même dérivé de Yuzu. Il intègre le support du réseau Nextendo Network afin de permettre le jeu en ligne avec un système de comptes, de matchmaking et de connexion multijoueur. Il intègre également divers correctifs de compatibilité pour certains jeux.. Disponible sous Windows et Linux.
Ryujinx-Nextendo est un émulateur Nintendo Switch basé sur Ryujinx, auquel a été intégré nativement le support du Nextendo Network, un service en ligne privé et communautaire destiné à remplacer le service officiel de Nintendo.
Le projet reprend le cœur d’émulation de Ryujinx (Ryubing), notamment pour le processeur, le GPU, l’audio, les contrôles et le système de fichiers. Les modifications apportées par Nextendo concernent principalement la partie réseau et l’interface utilisateur.
L’objectif est notamment de permettre aux jeux compatibles de retrouver des fonctionnalités de jeu en ligne via le Nextendo Network, sans nécessiter de configuration manuelle particulière, de modification du fichier hosts ou de contournement SSL de la part de l’utilisateur.

RomSieve est un outil open source permettant d’auditer, trier et organiser des collections de ROM et d’images disque à partir de bases de données DAT (TOSEC, No-Intro, Redump et MAME). Il propose notamment la création de collections 1G1R (One Game One ROM), la détection des doublons et des disques manquants, la gestion des jeux multidisques ainsi que la génération automatique de playlists M3U. Il dispose d’une interface graphique et d’une ligne de commande et fonctionne sous Windows et Linux.
ReEmu est un frontend open source permettant de centraliser et d’organiser une bibliothèque de jeux rétro dans une interface graphique moderne, entièrement utilisable à la manette. Il s’appuie sur les cores Libretro pour assurer l’émulation de nombreux systèmes, sans être lui-même un émulateur.
Il propose notamment l’analyse automatique des collections de jeux, la récupération des jaquettes et des informations associées, la gestion des cores et des BIOS, ainsi que la configuration des shaders, des Bezels et des sauvegardes instantanées (Save States). Il intègre également un système de favoris, un historique et un suivi du temps de jeu.
De nombreuses plateformes sont prises en charge, notamment les consoles Nintendo, Sega, Sony et NEC, les systèmes d’arcade ainsi que plusieurs ordinateurs rétro.
OpenEmux est une interface graphique libre et open source inspirée d’OpenEmu, conçue pour simplifier l’utilisation de RetroArch. Développé en Python avec GTK4 et libadwaita, ce frontend permet de parcourir et d’organiser une bibliothèque de jeux rétro par système, avec affichage des jaquettes récupérées depuis les dépôts de miniatures de Libretro.
OpenEmux s’appuie sur RetroArch pour l’émulation et facilite sa configuration depuis une interface unifiée. Il permet notamment de définir les répertoires de jeux, de vérifier la présence des BIOS requis, de configurer les commandes clavier et manette pour chaque système et de gérer les shaders. Lors du premier lancement, l’application prépare son environnement et télécharge les cœurs Libretro nécessaires.
Initialement conçu pour Linux, le projet propose également une version pour Windows, distribuée sous forme d’archive portable et d’installateur, intégrant les dépendances nécessaires, ainsi qu’une version pour Android. Le portage Windows est développé et testé séparément de la plateforme Linux d’origine.
OpenEmux ne fournit aucun jeu ni BIOS. Le projet est distribué sous licence MIT, indépendamment des licences propres à RetroArch et aux composants tiers embarqués.
Game Format Converter (anciennement CHD Manager) est un utilitaire open source (disponible pour Windows et Linux) proposant une interface graphique conviviale pour chdman, l’outil de MAME dédié à la gestion des images disque.
Conçu pour convertir, compresser et décompresser des images de jeux en toute simplicité (glisser-déposer, menus contextuels Dolphin/GNOME Files, traitement par lots), le logiciel analyse automatiquement les fichiers et ne propose que les conversions viables. Il intègre de série des vérifications d’espace disque et une validation post-écriture.
Il prend en charge un très large éventail de formats et de consoles:
– CHD, PBP, CDI, VCD, CSO/ZSO, ECM, ISO, CUE/BIN, GDI (PlayStation, Dreamcast, Saturn, Sega CD, PSP)
– RVZ, WIA, WBFS, GCZ, CISO, WUX/WUD (GameCube, Wii, Wii U)
– ZAR, ISO et dossiers de jeux (Xbox 360) ainsi que la compression des dumps Xbox d’origine en .xiso.iso
– ISO, dossiers de jeux et paquets .pkg (PlayStation 3)
– NSP, XCI et NUP (Nintendo Switch et Switch 2, avec gestion des mises à jour et des DLC)
– .zcci, .cia et .3ds (Nintendo 3DS, avec compression pour l’émulateur Azahar)
Entièrement portable, le logiciel intègre une fonction de mise à jour facultative, un journal d’activité (log) et gère l’appel à des clés ou fichiers BIOS externes si requis par certains formats spécifiques, sans distribuer le moindre contenu protégé.
Voici les derniers émulateurs en développement, ainsi que ceux bénéficiant des mises à jour les plus fréquentes.

Les changements:
Games
– Paprium: the game’s cartridge chip is emulated in software, hooked in from outside the core. The Paprium support is by BillyTimeGames (Genesis-Plus-GX-Expanded-Rom-Size fork).
– MD+/32X+ games (for Mega Drive or 32X: a ROM with a .cue of the same name and WAV or OGG tracks) play their enhanced music. A Mega Drive game turns the MegaSD overlay on by itself; a 32X game is started from its sheet, as PicoDrive expects, and runs its sound at 44100 Hz whatever Settings > Audio > Sample Rate says (the other rates are grayed out while it runs): at 48000 Hz the music crackled. The ROM is listed, its .cue is not (this goes for MSU-MD games too).
– MSU-MD games (a ROM with a .cue and its audio .bin beside it, for Mega Drive or 32X) play their music. They need the Mega CD BIOS for the game’s region in BIOS. Open the ROM, not the .cue.
– Games in a .zip or .7z: a cartridge game that is not the first file of the archive (a ROM beside a soundtrack or a manual) now loads, and Paprium also reads its soundtrack from the archive. Mega CD discs (a .cue with its tracks, a .chd or an .iso) and MD+/32X+ games (the ROM, its .cue and the audio) load too: the archive is unpacked whole to a temporary folder while the game plays, and the folder is removed when it closes. The 7z reader now decodes the Delta and branch filters too. Note: a game kept in an archive like this takes much longer to start (the whole archive, audio and disc tracks included, is unpacked first), so it is better kept unpacked in a folder.
– A ROM with a .cue of the same name that lists audio tracks only (all the tracks in one .bin, as MSU-MD games have), in a .zip or .7z, is started as a game with music; before it was taken for a Mega CD disc and showed the Mega CD player.
– A Mega CD .cue sheet whose FILE line names its data file without the extension (FILE « Game » BINARY for Game.bin) now loads; before, the disc showed a black screen.
– A .cue or .chd that cannot be read as a disc (its track files are missing) now says so; before, its text was run as a ROM and the screen stayed black.
– ROMs up to 96 MB (the limit was 32 MB; this takes the large Sega Channel Revival images).
– File > Run Mega CD BIOS (USA, Europe, Japan): the BIOS on its own, with no disc.
– Controls > Player 1 / Player 2 > Allow Opposing Directions: lets Left and Right, or Up and Down, be held together (a real pad cannot do it, so only one of the two reaches the game unless this is ticked).
– Tools > Fix Checksum… and a second, header-range checksum in ROM Info.
– Emulate Mega CD Disc Latency is on at first, as in Genesis Plus GX (a CD game can show a black screen without the real drive’s delay).
– A Mega CD game that fails to start because its BIOS is missing now shows a message naming the BIOS file it needs (for example bios_CD_U.bin) and the BIOS folder to put it in.
Sega Pico
– The voices of the games play: the console’s speech chip is made in the program (from PicoDrive’s), as the Genesis Plus GX core leaves it out.
– Page Down and Page Up (Input > Hotkeys) turn to the previous and next page of the storybook, up to page 7. LB and RB do it on an Xbox pad.
– Default controls: D-pad = arrow keys / pad D-pad or left stick; red button = Z, X or C, the right mouse button, or the pad’s face buttons; pen = the mouse (left button), or the right stick with RT / R2 / R3 / Start to touch; previous / next page = Page Down / Page Up, or LB / RB (L1 / R1 on a PlayStation pad, L / R on a Switch pad: the same places on any pad).
– A Storyware window shows the open page as big as its picture, and opens with the closed book when the game starts. The pictures are your own scans in Images/Pico-Storyware/
– The pen is the mouse: over the game it is on the pad, where the game draws its own pointer; over the Storyware window it is on the book’s page, so what is printed in the book can be clicked. The right stick of a gamepad moves the pen too (RT, a press of the stick or Start touches with it).
– The D-pad and the red button follow Player 1’s D-pad and A, B or C button.
– The mouse pointer is hidden over the game, and the gamepad hotkeys on the right stick, Fast Forward and Rewind are off.
– The Storyware window goes with the program’s window when it is minimized or brought back, and bringing the Storyware window back from the taskbar brings the program’s window back too.
Themes
– Seven new colored dark themes: Sapphire, Ruby, Emerald, Amethyst, Amber, Aquamarine and Diamond (View > Theme, or Settings > General). Backgrounds, text boxes, lists, menus, toolbar, title bar (Windows 11), buttons, drop-downs, the back-to-top button and the scroll bars of lists and text boxes follow the theme.
– The Style and Theme choices keep the View menu open, like the other View choices.
Debugger
– One Debugger window (Tools > Debugger…) with tabs (Memory, VDP, Sound, CPU, RAM Search, RAM Watch) and a View menu; its own taskbar button.
– CPU Debugger: breakpoints on execute, read and write, step into / over / out, run to cursor, disassembly, registers and a call stack for the 68000, and for a 32X game also the Master and Slave SH-2.
– Memory Viewer (hex, every memory can be edited), VDP Viewer (registers, palette, tiles, planes, sprites, scroll plots), Sound Viewer (FM envelopes, PSG, PCM, 32X PWM) and CPU Viewer.
– RAM Search and RAM Watch, also for the 32X SDRAM; a RAM Watch list is opened and saved from the RAM Watch tab (Open… / Save…, the .wch format of Gens).
– A tooltip on every control of the debug windows.
– Credit: the debug tools are a port of gpgx_debugger by Vladimir Kononovich (lab313ru).
Languages
– Options > Language loads translations from Languages/*.po (UTF-8, the gettext format). Only English ships; Languages/Template.pot is the template, so the community can make translations, for example with Poedit. A text left untranslated stays English.
– Windows made for English are fitted to longer text: buttons, labels, check boxes and drop-downs widen, dialogs grow, the Controls and Settings windows stretch.
– tools/make_pot.py makes the template again from the source.
Deinterlacing
– Video > Visual Effects > Deinterlacing: in a game that uses the 448-line interlaced mode (Sonic the Hedgehog 2 in 2P Vs. mode, Ys III, Air Strike Patrol …) the graphics processor draws both fields of the picture from the same moment in every frame, so nothing that moves is combed. It gives a cleaner picture than the Interlaced Mode of Genesis Plus GX. It does not touch other games. While it is on, Interlaced Mode is not used; it keeps your choice for when you switch Deinterlacing off.
Folders and Settings
– Settings > General > Data Folders…: choose where each folder beside the program is (BIOS, Cheats, Images, Languages, Profiles, Recordings, Saves, Screenshots, Shaders, States; by name), with a path box and a … button for each and a Defaults button. Files already in an old place are not moved.
– Images is a new folder beside the program: it holds Covers, Bezels and Pico-Storyware (the pages of Sega Pico books). If you used an older version, move your Covers and Bezels folders into the new Images folder.
– When the program’s folder cannot be written to (for example Program Files), settings, saves and the other data are kept in %LOCALAPPDATA%\Genesis Plus EX instead of asking you to move the program.
– Scan Subfolders moved into the ROM Directories window.
– File > Change Disc… (it was Insert Disc).
Controllers
– Controller layouts for DirectInput pads come from SDL’s game controller database (866 Windows pads, found by USB vendor and product id), on top of the maker’s layout for Sony and Nintendo pads.
– A trigger that is an analog axis can be assigned like a button (it shows as Axis Z+, Axis RX- …).
– Controls > Test Keys now names every pad button or axis the pad reports as pressed, mapped or not.
– The Controls window refreshes its device list by itself when a pad is plugged in or out.
– A pad button that is stuck is left out while listening for a button, so the others can be assigned.
– Switching between an Xbox pad and another kind of pad (PlayStation, Switch, a generic joystick) now gives the new pad its own default buttons, unless you had customized them.
– Settings, profiles and gamepad hotkeys are read and written with 64-bit button masks; files of earlier versions load as they were.
– Credit: the layouts are from SDL_GameControllerDB (zlib license, Copyright (C) 1997-2025 Sam Lantinga and the contributors of the database).
Picture
– Console Badge on Covers: a small coloured tag (MD, MCD, 32X, SMS, GG, SG, PICO) in the corner of each cover in the grid view, to tell the consoles apart. It can be turned off in Settings > General.
– Video > Window Size now goes up to 10x (it was 6x), and the window may be larger than the screen. A window dragged to a size keeps it when a game is loaded or closed, until a size is chosen again in Window Size. A Window Size you chose is kept when the program starts on a screen that is too small for it (it was lowered and saved); the top left of the window stays on the screen. The first run, with no size chosen yet, still opens at the size that fits.
– In the Video menu, the choices in Render Filter, Visual Effects, Scanlines, NTSC Filter, Aspect Ratio, Rotation and Borders keep the menu open after a click, like the View menu’s.
– Video > Picture Adjustments has a Brightness slider at the top (-50% to +50%).
– The mouse buttons did not reach the game with the Direct3D 11 renderer (the Mega Mouse, the light guns, the Sega Pico pen and red button, the Graphic Board pen); they do now.
– Show Light Gun Crosshair is on by default.
– Confine Mouse to the Picture: pressing the Windows key or Alt+Tab lets the pointer go until you click in the picture (it was held again at once, so after the Windows key the toolbar could not be reached).
– Hide Mouse Pointer has a new choice, Always, below Never.
– VSync with the Direct3D 11 renderer now waits for the display in the swap chain itself (a real VSync); the other renderers still wait for the Windows compositor. Still skipped for a frame whenever the sound buffer runs low.
– Skip Intro on Launch: the tooltip and the User Guide say the seconds are seconds of game time, which take much less real time.
– Video > Rotation: the picture turned by 90, 180 or 270 degrees, for games made to be played with the screen on its side.
– More render filters: MMPX 2x and MMPX Enhanced 2x (MMPX by Morgan McGuire and Mara Gagiu; Enhanced by CrashGG), 2x versions of Lanczos, Catmull-Rom, B-Spline, Mitchell, Sharp Bilinear and LCD Grid, and 4xSaI, Super 4xSaI, Super Eagle 4x, Eagle 4x and Scale4x.
Fixes and Small Changes
– Accented text in menus and the status bar is converted explicitly from UTF-8, whatever the code page of Windows is.
– Game names with Chinese, Japanese or accented letters show correctly in the game list and the grid (they were shown as other characters).
– Save-state buffers have room for Paprium’s chip on top of the core’s worst case.
– A save state remembers the checksum of the ROM it was made from: loading it into a different ROM (two files with one name share their saves) asks first instead of crashing the game.
– Open Game Folders submenu shows the game’s ROM in Explorer and opens its saves, states and cheats folders.
– File > Open ROM… starts in the ROMs folder beside the program when no ROM directory is set (it was Documents).
– Command line: –config FILE uses another settings file, and –profile NAME a controls profile.
– Refresh (toolbar and right-click menu) looks at every file again, instead of using the saved game list.
– The File Type column of the game list tells what is in an archive, then the archive: MD (ZIP), 32X (7Z), MCD (ZIP).
– The filter bar has a Filters: label, its button is Reset (as wide as the search bar’s Close) and both buttons have tooltips.
– The log is far more complete: the machine, the whole settings file, a report for each game and a summary when it closes.
– While the game is paused, each press of the rewind key goes back one frame (held longer, frame after frame), and Tab advances one frame like the frame button advance key (\).
