A LITTLE TOOL BY 589 SOFTWARE

R36S image
converter.

Make your handheld feel like yours. Turn an image into a properly sized BMP, pick a screen design, and give your R36S a fresh welcome.

01 / MAKE IT YOURS

One image. Ready to boot.

Your image stays in your browser.

Or drop it here. PNG, JPEG, WebP or BMP.

Up to 25 MB and 40 megapixels.

No image selected

Output size

640 × 480 is a common R36S boot-logo size. Match the image you’re replacing if it differs.

BMP: logo.bmp, 24-bit, uncompressed.
JPEG: loading.jpg, for screens that require it.

Choose an image to begin.

640 × 480 / MADE FOR YOUR HANDHELD

640 × 480 px · 24-bit BMP · 921,654 bytes

Check the preview before downloading. “Fill” crops the edges; “Keep the whole image” adds borders in your chosen background color.

The filename matters. Before copying any download to your SD card, rename it to the exact name of the file you’re replacing, including capitalization and extension. logo.bmp is a common example, not the name for every screen. Renaming a BMP to .jpg does not convert it—use the JPEG download when needed.

02 / PICK YOUR PALETTE

A screen to match your style.

Free screen designs from 589 Designs, now at home on 589 Software. All designs are 640 × 480. Download the original BMP or JPEG, or open it in the converter to resize it and change formats. Match the format required by the screen you’re replacing.

These are image files, not firmware or themes. The low-battery design only changes the artwork on a compatible screen; it does not add a battery warning feature.

03 / FROM BROWSER TO HANDHELD

Put it on
your R36S.

You’ll need your handheld, its microSD card, a computer and a microSD card reader (or SD adapter).

R36S devices ship with different firmware and card layouts. Treat folder names as starting points, then check the actual files on your card.

Back to the converter

  1. Notice which screen you want to change.

    Watch the device start and launch a game or app. Remember the artwork—or take a photo. The first boot logo, later startup screens, game-loading screen and low-battery image can be separate files.

  2. Shut down, then connect the card.

    Use the device’s shutdown menu and wait until it is fully off. Remove the operating-system microSD card, usually in the slot labeled TF1 / OS, and put it in your computer’s card reader. In a two-card setup, the second card may hold the games and some loading images.

    If your computer asks to format or initialize an unreadable partition, cancel. A Linux partition may not be readable by Windows or macOS; that does not mean it is empty or broken.

  3. Find the original image and back it up.

    Start with the locations below. Copy the original to a backup folder on your computer before replacing anything, and note its full path, exact name, dimensions and file type.

    First boot logo

    On many ArkOS setups, look for logo.bmp at the top level of the BOOT partition. It commonly uses 640 × 480 pixels and 24-bit BMP.

    Game-loading screen

    Look for launchimages on the ROMs partition, often labeled EASYROMS. ArkOS can use loading.jpg in /roms/launchimages/ or /roms2/launchimages/. That file needs a JPEG export.

    These are ArkOS examples: boot-logo documentation and loading-screen documentation. Other firmware may use different locations or formats.

  4. Different folders? Search for the picture.

    Search each readable partition on the entire SD card for .bmp files, then preview the results. On Windows, open the card in File Explorer and search for *.bmp. On macOS, open the card in Finder, search for .bmp and choose the card as the search scope instead of “This Mac.”

    Look for the image you recognize from the device. If you can’t find it, also check .jpg and .png, including folders named boot, BMPs, logos or launchimages if present. A folder name is a clue, not proof: confirm the artwork and its use before replacing it.

    A computer search only covers mounted, readable partitions. If the original is elsewhere, use your firmware’s file manager or documented file-transfer method to find it.

  5. Match the image, then match the name.

    Use the converter to match the original’s dimensions and format. For a BMP boot logo, the default export is 24-bit and uncompressed. If the original is a JPEG, use Download JPEG. If it needs a PNG, keep that format in an image editor.

    Rename your download to exactly the original filename, including uppercase/lowercase letters and the extension. For example, replace logo.bmp with a new logo.bmp, not RedYellowWelcome.bmp or logo.bmp.bmp. Show file extensions in your file manager so you can check. Then copy it into the same folder and replace only that image.

  6. Eject, reinsert and try it.

    Safely eject the card’s mounted volumes, return the card to its original slot, and turn on the R36S. Test the same startup or game-launch step you noted earlier. If the result is wrong, shut down again and restore the backed-up original.

    If the picture later changes back, your firmware may cycle boot logos from another folder or regenerate the file. Check its documentation and the images it actually uses before changing more files.

A FEW USEFUL DETAILS

Before you swap screens.

Why use this instead of renaming an image to .bmp?

An extension does not change the file’s encoding. This converter writes a real 24-bit uncompressed BMP, including the bitmap headers and row padding. Transparent parts are filled with your selected background color.

Why do the boot logo and loading screen use different files?

They appear at different stages: firmware draws the initial boot image, while the game frontend can draw a separate loading image. Change the file that matches the screen you want, and keep its required format and filename.

Can I use my own image, and is it uploaded?

Yes. Choose an image or drag it into the converter. Resizing and export happen locally in your browser; the converter does not upload or store your image. Animated images are exported as a single still frame.
