A fan-made virtual-pet project for the LilyGO T-Display-S3 LCD, combining raising, local/online battles, downloadable artwork, adapter tools and D-Vault. Start with the Manual’s first steps.

No. It is an unofficial fan-made accessory and is not affiliated with, endorsed by or produced by Bandai. Digimon and related characters belong to their respective rights holders.

The LilyGO T-Display-S3 LCD model. The older ESP32 T-Display, AMOLED, Pro and other ESP32-S3 boards need their own explicitly supported firmware.

Reviewed for Stable 1.2.23 on 29 October 2026. Beta 1.2.24 has an additional Wi-Fi Setup shortcut on Missing Sprites. Beta-only instructions are marked. Check your installed version before following version-specific recovery steps.

Some care/evolution concepts follow DMC, while training, Venture/Arena progression and presentation include custom behavior. Use your installed pack’s Guide and the implementation notes for the applicable rules.

Open Status → Manage → Slots, select the empty Pet2 slot, choose an egg with A and confirm with B. Egg choices depend on installed packs. An occupied slot is not replaced by selecting it. See pet management.

Open Status → Manage → Freeze and select Pet1 or Pet2. ON means that pet is frozen; OFF means unfrozen. Freeze pauses that occupied pet’s care/evolution timers. It is separate from Light off and Screen Off. Full steps.

Clear the grave with its confirmation, then open Status → Manage → Slots and choose the empty slot to select a new egg. Clearing alone leaves the slot empty, including after restart. Grave and egg steps.

Status → Guide compares an active pet’s next-route requirements with its current values. Status → S3Dex browses built-in/installed game-line rosters, species details and routes. The Manual shows both.

Open Status → Manage → Storage. Select an empty slot to store Pet1/Pet2, or an occupied slot to restore/swap it into Pet1/Pet2. There are 30 slots. Stored parameters remain paused; their artwork must remain available. Storage instructions.

In Status → Manage → Storage, select a stored pet and choose Toggle Farm. Return Home and hold A for about 0.9 seconds to switch Main ↔ Farm. See the illustrated Farm guide.

Farm displays up to six selected pets at once; local storage still has 30 slots. Toggle one selected pet off before adding another. A missing pack can prevent a selected pet from appearing. Farm selection.

Farm is observe-only. The selected stored pets’ walking, happy and sleeping poses do not advance their care or evolution. Your active pets have separate care/pause state; switching the view does not Freeze them. Farm behavior.

Open Status → Player → Name. A changes the highlighted character; B advances. Press B after the fourth character to save, or hold B to cancel. See Status and Player.

Use Training → Train for mini-games, Training → Solo → Venture/Arena for solo play, and Training → Link → Battle/Jogress for connections. Battle paths and walkthrough.

Random Fire is best of three: stop the moving aim. Power Charge requires repeated presses before time runs out. Precision Stop requires stopping the marker in the target. Short A or B provides the action. The last two have five unlockable levels. Controls and level rules.

A completed win or loss increases the exact Training Sessions counter for eligible unfrozen active pets. Only success improves strength/effort and reduces weight. Cancelling is not a completed session. Effort Hearts and Training Sessions are different measures. Training counters.

Stage I–II cannot battle. Stage III/Rookie and above need at least 1 DP. Empty/grave slots cannot participate, and an active Competitive/transfer lock may block an action. Wi-Fi battles also need a working network/service and opponent. Battle requirements.

In solo battles, READY leads automatically to POWER charging. Repeated short A/B presses fill the bar; full charge triggers MEGAHIT. It strengthens the attack but does not guarantee a win. See the original frames and sequence.

The result animation is followed by pet reactions and applicable progress/reward screens. Venture may show area completion or item/coin rewards; Arena milestone wins can unlock poo colours. The exact sequence depends on the mode and outcome. Battle-screen walkthrough.

OK follows a completed prong exchange and leads into battle playback or an eligible Jogress evolution. RETRY means the exchange needs another attempt. Check the toy mode and connection; hold B cancels waiting. Communication screens.

Check that the room light is on, an eligible Stage III+ pet is available, and an unlocked area is selected. Screen power is a separate setting. Venture offers Walk, Map, Road and Items. Venture instructions.

Read the selected route’s partner/readiness requirements in Guide. The Link → Jogress menu offers local P1–P2, Prong and supported Dummy routes. ESP-NOW partner routes need the listed partner on another updated WiFiCom. Jogress and evolution rules.

Open Light → Content, then Updates, Sprite, Wallpaper, Attack Skin, Menu Icons, Light off, Farm Wallpaper or Poo Color. Download/manage actions live inside the relevant category. Every category and path.

Yes. Wallpaper controls the normal room, Light off controls the night background, and Farm Wallpaper controls Farm. Farm uses the normal wallpaper if no Farm background is selected. Wallpaper selection.

An already-owned menu pack or Light off/Farm wallpaper can be reinstalled or updated without another unlock charge. A new paid item shows its price and asks for confirmation. Deleting its local file does not remove ownership. Content and coins.

Attack artwork advances every ten accepted Meat feeds, with applicable Venture first-clear credit also advancing progress. Assign installed attacks through Attack Skin → Manage Attack to Pet1/Pet2. Arena milestones unlock poo colours; the first hidden-area Venture clear unlocks Rainbow. Unlock details.

Settings → System → Firmware updates the device application. Light → Content → Updates updates or restores artwork/content. Update All processes compatible entries and reports failures. Firmware · Content.

Open Connect → Tools. Punching Bag runs a toy-specific preset; BD Dex → Reader detects supported connected Color toys and records collection entries; Power Check inspects supported battle data. The Tools guide explains selection, connection, results and cancellation.

Sync Sprites downloads Dex preview artwork over Wi-Fi. Reading a supported physical toy records its collection entry. S3Dex is a separate built-in/installed-roster reference. BD Dex versus S3Dex.

WiFiCom uses a 48×48 runtime canvas. Packs can use different source proportions and conversion choices. The LCD and your Color Tuning also affect appearance. Try neutral sprite contrast/saturation before reporting a colour issue, and include the pack/species. Display tuning.

Yes, when prepared in the supported pack format with compatible artwork, metadata and evolution data. A full playable pack differs from a Dex preview asset. Keep original custom files because online recovery may not have them. Content guide.

Open Settings → Display → Menu Layout, choose Large Icon or Grid 2×4 with A, then B to save. This changes the main icon menu; submenus remain lists. Illustrated layout choices.

Choose Settings → Display → Extra Clock → On. Short B on idle Home still opens the separate large clock. Clock10x is a testing-speed setting, not a clock-display option. Clock controls.

Brightness changes the backlight. Color Tuning provides gamma, sprite contrast and saturation. Menu Color changes menu panels/highlights. These adjustments apply/save as you change them. In Color Tuning use A to adjust and B to change row. All Display settings.

Open Settings → Wireless → Setup Hotspot, join the displayed setup network, then use its QR code or http://192.168.4.1/. Save your home network credentials and follow the reboot instructions. Hotspot steps and radio policies.

No. Sleep Timer and Screen Off control the physical display. Room Light off supports pet sleep, while Freeze pauses an occupied pet and storage pauses stored pets. Use the correct option for the effect you want. Care and sleep.

Check Settings → System → Debug and Clock10x. Sprite Debug cycles artwork for inspection; Clock10x accelerates care/growth timers for testing. Turn both Off for normal raising. System settings.

There are unread system messages. Open Settings → Messages for the inbox, Check Now and Auto Check. A first rewarded read grants one coin once. Messages and automatic checking.

Settings contains Sound, Storage and System. Sound offers V1/V2/Max/Mute; Storage shows usage and cleanup; System → Load/Save contains Autosave and Save1/Save2. Check deletion/replacement prompts before confirming. Complete Settings guide.

Desktop Chrome or Edge with USB Web Serial support is recommended. Use HTTPS and a USB data cable. Android availability depends on native USB serial support in the device, OS and browser; a mobile Chromium browser alone does not guarantee compatibility. USB requirements.

Signed OTA and the current Firmware Recovery installer preserve storage on a supported layout. Fresh Install erases the whole device, including saves/settings/content. Make a USB backup before recovery when the device can still run. Choose the correct method.

Save1/Save2 are on-device snapshots under Settings → System → Load/Save. A USB backup copies progress and recovery information to your computer, useful for migration or device failure. Loading/restoring replaces target progress. Save and backup steps.

No. Start WiFiCom normally, return Home or to the startup Load prompt, then connect USB. BOOT is used for the browser firmware-installation procedure, not normal USB save transfer. USB backup/restore.

Firmware 1.2.23+ backups include saved Wi-Fi networks and unencrypted passwords: keep the file private. Artwork itself is not included; the backup records what to recover. It transfers directly over USB, not to the website. Contents and privacy.

Use compatible firmware, make a fresh USB backup and restore it to the target. The target must run the backup’s build or newer. It keeps its own device identity/D-Vault pairing, so pair it separately. Recover missing published content through Updates. Migration walkthrough.

That screen protects the save while required active-pet artwork is unavailable. B opens Updates; hold B opens Light/Content. Recover the exact recorded published files. Unavailable/custom packs need their original files. Recovery steps.

Beta 1.2.24 adds A: Wi-Fi Setup directly on this screen. Configure the network, reboot/load, then B: Updates. Stable 1.2.23 lacks that shortcut. A Wi-Fi-inclusive restore replaces the target’s networks, so use a network carried in the backup, or prepare the source’s new Wi-Fi profiles before exporting. Version-specific recovery.

Keep the required pack’s original files and reconnect Wi-Fi. A failed staged download should not be treated as a completed install. Retry from its category or Content → Updates; Missing Sprites must be resolved before continuing affected saved progress. Download/recovery guide.

Keep the device powered and reconnect. Resume the pending transfer/recovery flow before another transfer. Avoid Reset, unpairing or overwriting the slot until both device and service confirm the outcome. D-Vault transfer instructions.

If the device still boots, save and make a USB backup first. Check power, USB data cable and the exact installer message. For application repair, use the storage-preserving Firmware Recovery option; Fresh Install is destructive. Update and recovery methods.

New registration depends on the service’s current availability. The sign-in page states whether it is open; existing users can sign in when registration is closed. Pair this device under Status → Manage → DVault. D-Vault guide.

Include firmware version/channel, hardware model, exact menu path, pack/species, expected behavior and what happened. Add clear device photos/video with Sprite Debug Off. Keep passwords, USB backup contents, room tokens and private account details out of public reports. Support checklist.
