Identify the exact Mini before selecting software
This section covers Sega Mega Drive Mini and Genesis Mini products. Photograph the underside model label, region markings, power specification and connectors. Record whether the unit is a first-generation Mini or a Mini 2. A retail name containing Genesis, Mega Drive or Mini does not establish compatibility with a particular installer. Earlier licensed plug-and-play products, original cartridge consoles and the later Mini 2 require separate documentation.
Start the console in its current configuration and record the menu language, built-in titles, controller behavior and any visible modification branding. A second-hand console might already contain a replacement launcher. Keep those observations with the purchase records; a menu screenshot is more useful than remembering that the previous owner said it was hacked.
Understand the available project routes
Hakchi2 CE publishes support for Sega Mini systems alongside its Nintendo Mini work. Select the exact device type and read that release's instructions. Project Lunar is another historical first-generation route, but its current publisher says active development is on indefinite hold. The ModMyClassic homepage now points readers toward archived project material after a hosting failure. An old tutorial should be dated and matched to its original package.
This wiki does not infer Mini 2 modification support from first-generation support. Sega's stock Mini 2 FAQ describes a fixed built-in library without downloadable game additions. Before considering a community installer, require an explicit Mini 2 compatibility statement from that project's own release documentation. Similar cases and USB connectors are insufficient evidence.
Prepare a reproducible first session
- Choose one documented project and release. Retain the downloaded archive, release notes and original installation instructions together.
- Make a separate working directory for this console. Record the serial privately and identify any backups by device, region and date.
- Use a verified USB data cable and a direct computer connection for detection. First confirm that the computer recognizes the expected device before starting a write.
- Read the complete backup, install and uninstall procedures. Establish which files the tool can preserve and whether those files are sufficient for its documented recovery path.
- Install the minimum configuration first. Verify the original menu and one original game before adding software, extra cores or USB storage.
Keep compatibility claims narrow
A launcher changes software management; it does not establish that every added game works with the stock emulator. Record the selected emulator, required BIOS, game image format and controller mapping separately. Test startup, audio, saving and return-to-menu before expanding the library. Keep a known working configuration so a later experiment can be compared with it.
If documentation assumes a previous project is absent, follow that project's own uninstall procedure first. Combining installers without a supported migration path makes the final state difficult to diagnose. Continue with library and save preservation and recovery preparation.
