On an Analogue Pocket, playing a GBA game file is a separate openFPGA setup rather than the Pocket’s normal cartridge experience. Update the Pocket, install a compatible GBA core, copy the required BIOS and your legally usable game files to the exact SD-card directory, then launch the core from the openFPGA menu. The documented Spiritualized GBA core uses /assets/gba/common/ for both gba_bios.bin and ROM files.
Check the current Pocket firmware and the core maintainer’s instructions immediately before you begin. Firmware, core packages, filenames and directory layouts can change, and another FPGA handheld may use an entirely different process.

What this method does—and what it does not mean
The Analogue Pocket is compatible out of the box with physical Game Boy, Game Boy Color and Game Boy Advance cartridges. Analogue’s product page states: “Pocket is compatible with Game Boy, Game Boy Color and Game Boy Advance game cartridges.” That cartridge support is distinct from loading files from an SD card.

That technical capability is not a license to download or use games you do not have the right to use, and it does not establish that a personal backup is lawful everywhere. Use only files you are entitled to use under the law that applies to you.

The steps below are specifically for an Analogue Pocket using the Spiritualized GBA openFPGA core. Do not assume that another FPGA handheld, or even another Pocket core, uses the same BIOS name or folder. Analogue’s openFPGA documentation describes a package-based system in which cores and their assets are placed on the Pocket’s SD card: Analogue’s openFPGA overview and Getting Started with openFPGA.
What you need before copying anything
- An Analogue Pocket with a microSD card inserted. The cited documentation requires a card for this file-based workflow but does not specify a capacity, speed class or brand.
- A computer with a way to read the card. A USB microSD reader is convenient but is not identified as mandatory; you can use any reliable method that lets you copy files to the card.
- The current Pocket firmware instructions from Analogue’s Pocket Support page.
- The current release and installation instructions for the Spiritualized GBA core from its maintainer’s repository: https://github.com/spiritualized1997/openFPGA-GBA.
- A GBA BIOS file named
gba_bios.binobtained through a lawful source. The core documentation establishes the filename and location, not a source or permission to download a BIOS. - GBA game files you are entitled to use. The instructions below do not recommend commercial downloading.
Back up any important files already on the card before changing its contents. Core packages can add folders and files, while a careless format or deletion can remove other cores, saves or configuration data.
Step 1: verify and update Pocket firmware
Open Analogue’s Pocket Support page and follow the current firmware procedure shown there. The page listed firmware v2.7, dated 2026-09-04 when this guide’s information was checked. That is a dated listing, not a promise that v2.7 remains the newest release.
- Read the support page’s current release notes and update directions.
- Download the firmware package only from the official support page and follow its stated placement and restart steps.
- Allow the Pocket to complete the update before installing or troubleshooting the GBA core.
- After the update, confirm that the Pocket starts normally and that the SD card is recognized.
If Analogue has changed the update process, use the current labels and files on the support page instead of trying to reproduce an older procedure. A core built or documented for a different firmware environment may require an updated package.
Step 2: install the GBA openFPGA core on the SD card
Download the current Spiritualized GBA core release and read its README before extracting it. Analogue describes openFPGA core packages as ZIP archives containing the directory structure that belongs on an SD card. The Spiritualized README likewise instructs users to unzip the contents onto the root of the Pocket SD card in the appropriate folders.

- Power the Pocket down and remove the microSD card, or use the card reader while the card is safely unmounted from the Pocket.
- Open the core ZIP on your computer; do not merely copy the ZIP file itself to the card.
- Extract the archive’s contents to the root of the SD card, preserving the folders supplied by the core.
- Eject the card cleanly, put it back in the Pocket and power on.
The root-level extraction detail matters. If you copy a containing folder so that the real package is buried one level deeper, the Pocket may not list the core. For example, the archive’s supplied assets directory should end up as /assets/ on the card, not /SomeDownloadedFolder/assets/. Do not rename core directories unless the maintainer’s current instructions explicitly tell you to.
Step 3: add the required BIOS file
For this core, place a BIOS file named exactly gba_bios.bin in:
/assets/gba/common/- At the SD-card root, open
assets. - Open
gba, thencommon. - Copy
gba_bios.bininto thatcommonfolder. - Check the spelling, extension and capitalization against the README. Avoid an accidental name such as
gba_bios.bin.bin, which can occur when a file manager hides extensions.
The requirement is technical: the README specifies the filename and directory. It does not provide a BIOS download and this guide does not link to one. Use a BIOS obtained in a way permitted by the law where you live.
Step 4: copy your GBA game files
The Spiritualized README says: “Place rom files in the assets/gba/common folder.” On the Pocket card, that is the same directory used for the BIOS:
/assets/gba/common/- Copy the GBA files you are entitled to use into
/assets/gba/common/. - Keep the original file extensions and names unless the core’s current README says otherwise.
- Do not put the files inside an additional folder beneath
commonunless the current instructions specifically support subfolders. - Eject the SD card cleanly before reinserting it in the Pocket.
There is no documented requirement here for a particular microSD capacity, transfer speed or manufacturer. Choose a card that fits your existing Pocket setup and follow the device’s current handling instructions; do not infer a performance guarantee from the absence of a stated specification.

Step 5: launch the GBA core and select a game
- Insert the prepared card and power on the Pocket.
- Open the Pocket’s openFPGA section.
- Select the installed Spiritualized GBA core.
- Use the core’s file browser to open a game from
/assets/gba/common/.
The exact menu wording can change with firmware or core releases, so use the labels displayed on your Pocket. If the core appears but the game list is empty, return to the directory checks below rather than copying files to random folders.
Troubleshooting: when the core or games do not appear
The GBA core is missing from openFPGA
- Confirm that the archive was extracted, rather than copied as a ZIP.
- Check that the archive’s folders were placed at the SD-card root. Remove any unintended extra directory level.
- Compare the card’s folder names with the current core README.
- Verify that the Pocket is running current firmware and restart it after reinserting the card.
The core launches but reports a missing BIOS
- Open
/assets/gba/common/and verify thatgba_bios.binis directly inside it. - Check for hidden extensions, capitalization differences and typographical errors.
- Do not substitute a differently named BIOS or place it in a similarly named folder; the documented requirement is the precise path and filename.
The game list is empty
- Confirm that the files are in
/assets/gba/common/, not only at the SD-card root or in a desktop download folder. - Check that the files were copied completely and that the card was safely ejected.
- Read the current README for supported extensions or naming rules if a release has changed them.
- Test the directory with one known-good file you are entitled to use, rather than moving many files at once; this makes a path or naming mistake easier to isolate.
The Pocket cannot read the card
- Power down before removing or reinserting the card.
- Inspect the card for a damaged filesystem or incomplete copy and restore your backup if necessary.
- Recheck the firmware support page for any card-preparation or update-specific requirement.
- If the card works on a computer but not on the Pocket, preserve the files, then consult current Pocket and core documentation before reformatting. Reformatting is destructive and is not a substitute for finding the required directory.
These checks follow from the documented package and path requirements. They are practical inferences, not a claim of independent hardware testing.
Choosing a transfer method
Ordinary microSD-card copying (the standard approach)
The normal workflow is to remove the microSD card, copy the core, BIOS and game files with a computer or card reader, safely eject it and return it to the Pocket. It is the most straightforward method for installing a core package and moving multiple files.
USB SD Access (a developer debugging feature)
Analogue’s Debugging Aids documentation describes a feature called USB SD Access. When enabled, it mounts the Pocket’s SD card to a computer or phone over USB-C. The documentation quotes a transfer speed of about 700 KB/s and says the method is not recommended for large files.
That figure applies specifically to USB SD Access. It is not a specification for every SD-card reader, the Pocket’s card slot or ordinary card copying. Treat USB SD Access as a developer/debugging convenience, not the default installation route. Use the documented setup and disable or exit the feature as instructed before normal Pocket use.

Playing a cartridge versus loading a file
There are two different goals that are often confused: playing a physical cartridge and loading a file through an openFPGA core. The choice depends on what you already own and whether you need a backup made from a cartridge.
| Approach | What you need | Setup and purpose | Documented limitations |
|---|---|---|---|
| Physical GBA cartridge | A compatible cartridge inserted in the Pocket’s cartridge slot | Out-of-box cartridge play; no openFPGA ROM directory is required | Does not by itself create a file on the SD card |
| Spiritualized GBA openFPGA core | Pocket firmware, microSD card, installed core, gba_bios.bin and an entitled game file |
File-based play from /assets/gba/common/ |
Core instructions, BIOS requirements and folder names can change; legality of a particular file depends on applicable law |
| Third-party cartridge-dump utility | A Pocket cartridge and a compatible utility release | Potentially creates a backup file from a cartridge; separate from simply launching a game | Availability and behavior may change, and the listed utility’s save-restore limits are significant |
Analogue’s product page describes cartridge compatibility, while its openFPGA documentation and third-party core README describe the separate SD-card workflow. Neither should be read as a blanket endorsement of copyrighted files.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Optional route: dumping a cartridge with a third-party utility
If your objective is to make a backup of a cartridge you own rather than obtain a game file elsewhere, the openFPGA Library lists kroy.CartTools version 0.9999.20260920.1, dated September 20, 2026, as a utility for identifying and dumping GB, GBC and GBA cartridges through the Pocket’s cartridge slot: kroy.CartTools listing.
This is an optional third-party path, not a prerequisite for the Spiritualized core. The listing says save restoration is alpha and that GBA saves are not restored. It describes verified save restoration for several named GB/GBC cases and says other cases remain untested. Do not extend those statements to GBA or assume that a dump includes a restorable save. The utility’s version, availability and behavior may change, so read its current listing and instructions before relying on it.
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Repair Windows errors before they cause bigger problems3Scan for outdated or missing drivers - takes under a minute- Read the utility’s current documentation and confirm that your Pocket firmware and cartridge type are supported.
- Insert the cartridge and follow the utility’s on-device procedure to identify or dump it.
- Keep the resulting file in a backed-up location before copying it to the GBA core’s
/assets/gba/common/folder. - Do not erase or alter the original cartridge while experimenting with an alpha save feature.
A cartridge dump may help when you already own the physical game, but it does not remove the need to check the law that applies to making or using backups.

Keeping the setup maintainable
Record the versions you installed
Write down the Pocket firmware version, core release and any utility version you use. When something stops appearing after an update, this record shows which component changed.
Keep the directory simple
Leave the core’s supplied directories intact and keep the BIOS and GBA files in the documented common folder. Avoid renaming folders for convenience; a path that looks equivalent to a person may not be equivalent to the core.
Back up saves and configuration
Before updating firmware or replacing a core package, copy important save and configuration files to a computer. The cited documentation does not promise that every update or third-party utility preserves every save, and the cartridge-tool listing specifically excludes restoration of GBA saves.
Quick wins for a faster PC:
Fix the driver behind crashes, sound loss and screen glitchesFind Drivers →Clear out junk files and repair common Windows errorsFree Scan →Recheck instructions after updates
Firmware and core packages evolve independently. Before repeating the setup on a new card or after an update, read the current Pocket support page and the current core README instead of relying on an old screenshot or remembered folder.
Practical checklist
- Current firmware instructions checked on Analogue Pocket Support.
- Spiritualized GBA core downloaded from the maintainer’s current repository.
- Core archive extracted to the SD-card root, with no extra enclosing folder.
gba_bios.binplaced at/assets/gba/common/.- Only GBA files you are entitled to use placed in the same folder.
- Card safely ejected and reinserted before launching.
- openFPGA opened and the GBA core selected.
- If anything is missing, path, filename, archive extraction and firmware checked in that order.
Bottom line
The documented Analogue Pocket method is precise: update the Pocket, extract the Spiritualized GBA core to the SD-card root, put gba_bios.bin and your entitled GBA files in /assets/gba/common/, then launch the core from openFPGA. The Pocket’s ordinary cartridge support and Analogue’s statement about copyrighted ROM files remain separate from this third-party technical workflow. Use current instructions, keep backups, and treat USB SD Access and cartridge-dumping utilities as specialized options rather than the standard transfer method.
