SAROO Dynamic Frontend 0.2.0 - SD card files
================================================

Windows users: the "SAROO Frontend Manager" download does all of this for you
(backup, install, verification, library and artwork). Use this package only
to install by hand.

Install by hand
---------------
1. BACK UP your card's SAROO/ssfirm.bin, e.g. copy it to
   SAROO/ssfirm.bin.orig on the card.
2. Copy the SAROO folder from this package onto the root of the SD card
   (merge it with the existing SAROO folder, replacing ssfirm.bin).
3. Optional: build the library and cover art with the manager, or with
   tools/saroo_fe_prep.py --sd <card> from the project.

Files
-----
SAROO/ssfirm.bin                SAROO's Saturn firmware + 7-line frontend hook

Back to stock
-------------
* Hold B at power-on (one boot), or Options (START) -> Stock SAROO menu.
* Permanently: copy ssfirm.bin.orig back over SAROO/ssfirm.bin.
* Deleting SAROO/frontend/frontend.bin also brings back the stock menu.

The firmware is built from SAROO revision in manifest.json. It pairs with the
SAROO MCU firmware of the same release or newer.

Not yet verified on real hardware - see docs/HARDWARE_TEST.md in the project.
