NeoGeo ROM Extractor launches with 29 supported games

Edit: Metal Slug 3 is now supported, thanks to terminatorhexs direct contribution (😁 thnx) So 30 games are supported now 🙏 ______________________________ I’m pleased to share the first public release of NeoGeo ROM Extractor. This is an early preservation-focused Python project designed to rebuild verified Neo Geo ROM ZIPs from supported PC releases that the user legally owns. This does not 'dump' game carts, but 'extracts' digital store versions on Steam/Amazon/GOG. The project uses a modular system: each supported game has its own extraction module, while the main extractor handles the shared workflow. The aim is to make the process cleaner, easier to test, and easier to expand over time. This first release supports 29 games: 3 Count Bout Alpha Mission II Art of Fighting 3 Crossed Swords Ghost Pilots King of the Monsters 2 Kizuna Encounter - Super Tag Battle Last Resort Magician Lord Metal Slug Metal Slug 2 Metal Slug 4 Metal Slug X Mutation Nation Ninja Commando Ninja Master’s Over Top Robo Army Samurai Shodown IV Sengoku Sengoku 2 Soccer Brawl Super Sidekicks The King of Fighters 2003 The Last Blade The Last Blade 2 The Super Spy Top Hunter Twinkle Star Sprites What it does Scans supported game folders Uses per-game modules to locate and extract ROM data Rebuilds emulator-ready Neo Geo ZIP files Validates output files using known hashes Handles game-specific extraction quirks through individual modules Keeps the core extractor general-purpose and reusable Important notes This project does not include ROMs, BIOS files, game data, or copyrighted assets. You must provide your own legally acquired source files. This is an early release, so support is intentionally limited. Some games may require further work, and some outputs may depend on the exact PC release version used. Current status The project is now ready for public testing and feedback. After this release, I may open a short request window for additional games, but support will remain focused on titles I can personally verify and test properly. Credits This project was informed by public Neo Geo preservation research and existing community work, including projects such as NGPrimeClaim, goNCommand, mslug-rom-extractor, and other documented extraction research. Full credits are included in the README. The goal is preservation, verification, and transparency. LLMs were used in the making of this project GitHub release: https://github.com/DrRetroMod/neogeo-rom-extractor

Not sure how many people know about this yet so thought it was worth making a post.

GDMENU Card Manager is an alternative to GDEMU SD for preparing your memory card to use with a Dreamcast with GDEMU ODE.

The notable features are that it includes the ability to shrink the games within the app, and it also lets you view the cover art if any is in the archive.

Latest version is multiplatform for Win/Linux/OSX. But GDI Shrinking only for windows right now.
There's a new beta version for linux/osx with support from compressed 7z and rar files. If you guys could help test it. Would be much appreciated.
