How to Turn Your Artwork into a Custom Tamagotchi On or Meets Wallpaper

To turn your artwork into a custom Tamagotchi On or Meets wallpaper, prepare a 128 × 128-pixel PNG, convert it into a wallpaper file with MyMeets Studio, then transfer that file using MyMeets. The artwork needs a limited palette and a carefully reserved corner color to avoid unwanted green areas. Artist Seline Jongman documents these requirements in her custom-content creation guide.

This guide takes you from an existing drawing to a selectable room background. It uses the desktop MyMeets workflow and includes a practical way to identify whether a problem comes from the image, conversion, or transfer.

Section 1

What do you need before preparing your artwork?

You need your Tamagotchi On or Meets, an image editor that can export PNG files, and the MyMeets package containing MyMeets Studio. Tama Town’s download page currently lists MyMeets V2.3.7 and specifies fully updated Windows 10 plus Bluetooth Low Energy support, either built in or through a compatible Bluetooth 4.0 USB adapter. These are the page’s documented requirements; check them before spending time converting your artwork. MyMeets download and requirements

MyMeets and MyMeets Studio handle different stages. Studio creates the custom content; MyMeets sends it to the toy through Bluetooth. Designer Bulleblue describes this division in her introduction to creating MyMeets content.

Keep three files as you work: your editable drawing, the exported PNG, and the compiled wallpaper TXT file. Use a shared base name, such as blue_studio, so you can trace a transferred wallpaper back to its artwork. This is an organizational recommendation, particularly useful when you begin revising colors.

Section 2

How should you adapt an existing drawing to 128 × 128 pixels?

Create a square canvas measuring exactly 128 pixels wide by 128 pixels high. Jongman’s guide specifies this size and recommends using layers so individual decorations remain easy to move or change. Export the finished image as PNG. Wallpaper canvas and export instructions

For a larger illustration, decide what must remain recognizable before resizing. A room drawing might depend on its window shape, floor line, and one distinctive decoration. Small lettering, fine textures, and closely spaced outlines are candidates for simplification. Treat the reduced image as a fresh composition: move objects, enlarge essential details, and remove marks that have become visual noise.

For example, imagine adapting your own drawing of a blue art studio. As an illustrative layout, place the wall–floor boundary around row 88, position a small shelf toward one side, and leave the lower center relatively plain. These coordinates are design suggestions, not device specifications. Their purpose is to give you a concrete starting arrangement that can be adjusted after viewing the result.

Inspect the image at its actual size as well as enlarged. Use the enlarged view to repair individual pixels; use the actual-size view to decide whether the room still reads clearly. Keep decorative detail where it contributes to the scene.

Section 3

How do you prepare the palette and prevent green patches?

For this MyMeets Studio workflow, plan for 15 artwork colors plus one reserved color. Jongman’s guide gives a maximum of 16 colors and recommends reserving a separate color for a corner pixel. Palette preparation guidance

Use the top-left pixel for that reserved color, and make sure the color appears nowhere else. In the original wallpaper tutorial, Wonderpuff reports that the converter uses the top-left color as transparent; reusing it throughout the picture can produce unwanted neon-green areas on the toy. This is a creator-documented workaround for the conversion process. Original top-left-pixel instructions

For the illustrative blue studio, you could allocate three blues, three neutral shades, three wood tones, two greens, two accent colors, one outline color, and one highlight color. That totals 15 visible colors. Choose a sixteenth color solely for the top-left pixel. The exact colors are your choice; the useful constraint is keeping the reserved color separate.

Check the exported PNG, not just the editor’s swatches. Resizing and soft brush edges can introduce intermediate shades. If your editor provides an indexed-palette conversion or color-count display, use it to inspect the final image. Preserve the editable original so palette adjustments remain reversible.

Section 4

How do you convert the PNG in MyMeets Studio?

Open MyMeets Studio and choose its wallpaper mode. Select the wallpaper image area, load your PNG, and enter the wallpaper’s name, price, and ID. Then choose Compile and save the resulting TXT file. These controls and the compilation sequence are described in the original MyMeets wallpaper tutorial.

Use a short, recognizable name for the first version, such as BLUE ROOM. Record the ID you choose alongside the filename so you can distinguish experiments. Avoid treating an ID suggested in an old tutorial as a universal requirement: Wonderpuff’s report about changing an ID to make a wallpaper appear is an individual troubleshooting observation, not a documented rule for every installation.

Inspect the Studio preview before continuing. Check the crop, the wall–floor boundary, and the colors of your main objects. If the preview has already lost important detail, revise the PNG before attempting a transfer. Compiling an image packages it for the workflow; it does not improve the underlying composition.

Section 5

Where does the compiled wallpaper file go?

Place the compiled .txt file inside the MyMeets installation’s assets/items/en or assets/items/jp folder, then launch MyMeets again. Bulleblue’s own download instructions confirm these folders and explain that new content appears when the application launches. Bulleblue’s MyMeets import instructions

If the wallpaper is missing, check both the English and Japanese selections in MyMeets. Bulleblue notes that content placed in the Japanese folder can still appear under the English tab. Also confirm that you copied the compiled TXT file rather than the source PNG. Folder and language-tab behavior

Keep the folder distinction clear: the image editor produces the PNG, Studio produces the TXT, and MyMeets loads the TXT from its assets directory. Following that chain gives you a specific place to check whenever a wallpaper disappears between stages.

Section 6

How do you transfer and select the wallpaper?

Select your wallpaper in MyMeets. On the Tamagotchi On, open Connection → App → Download. In MyMeets, choose Send, then Connect, and follow the connection prompts. Michiko Michi documents this transfer sequence on her custom-content instructions page.

For a Japanese Meets, use its corresponding app gift-receive option rather than looking for the English word “Download.” A Japanese walkthrough identifies the route as つうしん → アプリ → プレゼント. Meets transfer-menu walkthrough

After the transfer, check the room selection at Tama Depa. On owners report that transferred wallpapers become available under the store’s Room category, where they can be selected for purchase with in-game Gotchi Points. A completed transfer and an applied room are separate checkpoints. On wallpaper-selection instructions

How can you diagnose a wallpaper that does not work?

Check the earliest stage where the result differs from what you expected. The following sequence combines the creator documentation above into a practical diagnostic aid.

What you observe	What to check next
Important details are missing in the PNG	Rework the 128 × 128 composition before compiling.
Studio’s preview looks wrong	Inspect the exported palette, dimensions, and selected image.
The wallpaper is absent from MyMeets	Check the TXT location, relaunch MyMeets, and inspect both language tabs.
The transfer does not finish	Re-enter the toy’s receive screen and follow MyMeets’ prompts again.
Green areas appear on the toy	Check whether the top-left color occurs elsewhere in the artwork.
Transfer finishes but the room looks unchanged	Check Tama Depa’s room selection.

For transfer failures, wallpaper designer Jun specifically recommends reopening MyMeets and trying again; her instructions also note that a transfer can take several attempts. Treat this as a designer’s troubleshooting suggestion. Jun’s wallpaper transfer notes

Once the room is visible, make one kind of change at a time. Adjust the composition, palette, or individual details, then export, compile, and transfer again. Keep the version you liked so an unsuccessful experiment does not replace your only usable artwork.

Your finished wallpaper should preserve the parts of your drawing that matter at 128 × 128 pixels. Keep its editable source, PNG, and compiled TXT together, and use the device display to guide the final adjustments. That leaves you with both a custom room you can select and a repeatable process for your next illustration.
