A Classic Mini library is a combination of game data, menu entries, emulator choice and saved progress. Preserve the desktop tool's collection and the console's saves before reorganizing or synchronizing a large set. A list of game files alone cannot reconstruct every configuration decision.
Keep stable game records
Record title, edition, region, file checksum and the identifier assigned by the management tool. Keep any patch information and command-line options beside the unmodified input. Renaming a menu entry is different from changing the internal identity that links it to saves.
Use the project's documented game-adding and synchronization workflow. Start with a small collection and test browsing and launching. Cover art and metadata improve presentation but do not repair a bad image or supply an unsupported cartridge mapper.
Choose an emulator per title
hakchi's documentation describes both stock-emulator use and additional emulator modules. The correct choice depends on the game. NES cartridge mapper behavior and SNES special hardware can affect compatibility; the presence of a familiar file extension is not a complete compatibility test.
Record module and core versions with any alternative emulator setup. Test the exact scene or feature that previously failed, including controls, sound and a later loading stage. Avoid turning a single opening-screen test into a claim of perfect compatibility.
Suspend points and ordinary saves
Nintendo's menu manuals explain the stock suspend-point behavior, while hakchi's own tools provide their documented save-management features. Distinguish a suspend point or emulator state from a game's ordinary battery-backed save. Keep both where available because they preserve different forms of progress.
A state can depend on the emulator and version that created it. A migration to another core should first be tested using copied data. Do not overwrite the only save while checking whether another implementation imports it correctly.
Backup and migration checklist
- Record the console model, tool version and installed modules.
- Preserve the desktop collection, metadata, patches and launch settings.
- Export or copy saves using the project's supported method.
- Keep ordinary game saves and states clearly identified.
- Test a restore of one important game in the original environment.
- Try a copied subset in the new layout before deleting older entries.
Check that the latest checkpoint loads, not just that a file exists. Preserve the known-good emulator configuration and keep an untouched backup during migration. A save-management display can help locate files, but a restore test provides stronger evidence.
Space and organization
Watch available storage and the size of installed modules, images and saved data. Use manageable folders and test navigation after changes. If using documented USB storage support, retain its filesystem and directory layout with the backup and follow the project's shutdown procedure before disconnecting it.
A failed save can arise from low space, an unexpected path or incompatible state format. Compare those causes before deleting data or reflashing a kernel. Repeated large synchronizations are less useful than a controlled test with one known working title.
Use project selection for installation prerequisites and accessory diagnosis for intermittent power or storage faults. Contribute the tested model, emulator, save type and restore result when documenting compatibility.
