RetroArch core info file vs core binary on Android
The core binary executes emulation; its `.info` record supplies frontend metadata such as name, systems, extensions, firmware notes, and database associations. Updating Core Info Files cannot install or repair a missing or incompatible core binary, while replacing a binary does not guarantee matching metadata.
Do this in order
- 01
Record the RetroArch package/version and the core name shown under Information.
- 02
Check whether Load Core can select the binary and whether Information shows a library name and version.
- 03
Inspect the configured Core and Core Info directories without assuming shared-storage paths.
- 04
Use Update Core Info Files only if the distribution documents and exposes it.
- 05
Restart RetroArch, select the core, and test one authorized known-good item directly.
- 06
If loading fails, collect the log and verify CPU architecture, binary source and package boundary.
Decision and diagnostic table
| Object | Purpose | A missing object causes |
|---|---|---|
| Core binary | Runs emulator code | No execution or load failure |
| Core info file | Describes capabilities/metadata | Missing labels, extensions or firmware notes |
| Database | Recognizes content for playlists | Scan omission |
| Core backup | Version rollback copy | No automatic compatibility proof |
Metadata is not executable code
A polished core entry can still point to an incompatible binary, and an executable core can be hard to discover when its info record is absent.
Distribution policy controls updates
Some Android packages expose online updating and others ship cores through the package. Follow the official distribution's mechanism rather than mixing binaries from unknown sources.
A core and its metadata grant no rights to game or firmware data. Use authorized content and obtain emulator binaries only from their official distribution channels.
