Wallpaper Studio

X4 Sleep Wallpaper

Import any image — or generate one from the Pokédex — preview the 480 x 800 X4 output, then export a .bmp ready for sleep-image folders.

Drop an image here or select one above. Output stays fixed to the X4 sleep-image frame.

Output: 480 x 800 BMP, grayscale-ready for the X4.

Placement

Fill crops edge-to-edge, Fit preserves the whole image, Stretch forces a full-frame remap.

Anchor

Anchor controls crop bias in Fill mode and padding placement in Fit mode.

Output

Background

4-bit keeps gradients cleaner. 1-bit produces a smaller, higher-contrast bitmap.

Adjust

Rotation: 0°

Export stays fixed to 480 x 800 even when the source image is rotated.

Pokédex

Generate a Pokémon wallpaper in the browser, download the PNG, then import it above to apply placement, depth, and rotation before exporting the final BMP. For the full party flow (per-book assignments, levels, evolution), enable pokemon_party in the feature grid.

Open Generator Open on Device

Device Handoff

Put the exported BMP in /sleep for Custom source mode. For Pokédex wallpapers, use /sleep/pokedex.

Open /files

No image selected. This tool runs entirely in your browser and exports an X4-ready BMP.

Screen Previews

Auto-generated PNGs from the firmware UI harness. Regenerate with the commands in configurator/README.md.

Plugin Modules

Anki Flashcards WIP

This feature is a work in progress and not yet complete in this build. Card capture works but the review flow and export are still being built out.

Create flashcards while reading — select a word or phrase for the card front and capture its surrounding sentence as the back. Browse, edit cards, and manage your deck from the device web UI at /plugins/anki. Export as JSON for import into Anki Desktop.

Pokédex Wallpaper

Generate Pokémon wallpapers for sleep screens. The browser-side generator lives in the Wallpaper Studio tab; the device-side plugin is at /plugins/pokemon-wallpaper.

Requires pokemon_wallpaper_plugin in the feature grid. Enable pokemon_party for per-book party assignments.

Baked Settings

Pre-configure device-side settings. Download settings.json and place it at /.crosspoint/settings.json on the SD card. The device loads these on first boot. Settings on the left are generated from firmware and use the same layout as the on-device Settings screen; the preview on the right shows reader, home, and sleep effects.

interactive webui preview

Illustrative preview only. Edit values in the Settings panel; only non-default values are written to the exported settings.json.

Only changed/non-default values are included. The device merges this file with its existing settings on load — fields not present keep their current values.

WiFi

Add up to 8 networks. Download wifi.json and place it at /.crosspoint/wifi.json on the SD card. The device imports on first boot, connects to a matching network, then re-saves with device-specific obfuscation.

No networks added yet. Click + Add Network.

Passwords are stored as plaintext in this file. The device XOR-obfuscates them with its MAC address on import — the file on SD is not long-term sensitive, but treat it like a password file.

OPDS Servers

Add up to 8 OPDS catalog servers (e.g. Calibre, Booklore/Grimoire). Download opds.json and place it at /.crosspoint/opds.json on the SD card. The device imports on first boot and re-saves with device-specific obfuscation.

No servers added yet. Click + Add Server.

Passwords are stored as plaintext in this file. The device XOR-obfuscates them with its MAC address on import — treat it like a password file.

KOReader Sync (Booklore/Grimoire)

Pre-fill KOReader (KOSync) progress sync. Enter your Booklore/Grimoire base URL and the KOReader credentials you set in Booklore (Settings → Device). Download koreader.json and place it at /.crosspoint/koreader.json on the SD card. The device imports on first boot and re-saves with device-specific obfuscation. Books must be downloaded via the OPDS feed; matching is Binary.

Booklore / Grimoire base URL

KOReader username

KOReader password

The password is stored as plaintext in this file until the device re-obfuscates it on import — treat it like a password file. Prefer the on-device web UI "Use for Sync" button if you'd rather not write credentials to a file.

Custom Fonts

Official Font Manager

Custom SD-card fonts now use the upstream Font Manager. It converts TTF/OTF font families into CrossPoint .cpfont files with the current upstream workflow, including Unicode coverage presets and multi-style family export.

Open official Font Manager

Upstream currently notes that custom SD-card fonts require the beta firmware. After generating the files, upload them from the device's Fonts page or copy them to /fonts or /.fonts on the SD card.
