Jester Nintendo Manager — Native Linux 1.3

Choose a .gba file or a ZIP containing one GBA game. Check the detected save
configuration, choose an output folder, and click Make CIA.

Emerald, Ruby and Sapphire use 128 KB Flash + RTC. Uncertain save types require
you to select the correct configuration. The Cover art section accepts a local
PNG, JPG, WebP or BMP for both the HOME Menu icon and top-screen banner. Images
are previewed, fitted without cropping, and kept locally for each game. Separate
icon/banner images are also supported. Rebuild the CIA to apply an art change.
Find cover opens an image search in your browser only when you click it.

Version 1.1 corrects the GBA save allocation for 128 KB flash games: both the
extended header and title metadata reserve 0x40400 bytes for two save records.
Rebuild affected CIAs. Existing installed save containers may still need repair;
back them up before making changes. File checks now report insufficient storage.
Rebuilds preserve the title ID and increase the title version.

Copy to card creates or uses its CIA folder, flushes the whole filesystem and
verifies the copy. It never overwrites a different file. Click Eject card and
wait for the safe-to-remove confirmation before disconnecting it. An error
means keep the card connected. Version 1.2 adds this explicit eject step.
On a 3DS with custom firmware: FBI > SD > CIA > select file > Install CIA.

Recent CIAs keeps your latest builds. Tools can check unencrypted CIA integrity
and back up selected save exports. This is not an encrypted 3DS save extractor.
Other console formats need different conversion engines; this version is GBA.

Version 1.3 adds an interface language menu and offline fonts. Open the menu
at the top right, choose Language, then close and reopen the manager. Your
chosen language is saved separately from game settings and build history.

Game conversion stays local. No account, telemetry or network listener.

The GBA container template comes from vcoven. See vendor/vcoven/README.md
for its composition and vendor/provenance.json for tool hashes. No ROMs are
bundled. Nintendo signatures are not validated for custom titles. Package
checks do not replace a boot/save test on the actual 3DS.
