Please report any issues encountered to this repo. Most likely any problems are a result of my port, not the original core. Issues will be upstreamed as necessary.
I highly recommend the updater tools by @mattpannella and @RetroDriven. If you're running Windows, use the RetroDriven GUI, or if you prefer the CLI, use the mattpannella tool. Either of these will allow you to automatically download and install openFPGA cores onto your Analogue Pocket. Go donate to them if you can
Download the core by clicking Releases on the right side of this page, then download the agg23.*.zip
file from the latest release.
To install the core, copy the Assets
, Cores
, and Platform
folders over to the root of your SD card. Please note that Finder on macOS automatically replaces folders, rather than merging them like Windows does, so you have to manually merge the folders.
ROMs should be placed in /Assets/wonderswan/common/
You must provide the BIOS files for both the original and WonderSwan Color. The BIOSes should be named bw.rom
and color.rom
, and should be placed in /Assets/wonderswan/common/
.

Known as "Memories" on the Pocket, this core supports the creation and loading of save states, and by extension, the core also supports Sleep + Wake functionality. Tapping the power button while playing will suspend the game, ready to be resumed when powering the Pocket back on.
Hold the -
button (default) to run the WonderSwan at 2.5x speed. Tapping the button will lock fast forward on, and it will continue fast forwarding until the button is pressed again.
The WonderSwan has a lot of buttons for a handheld in an unusual layout. The default button mappings for the Pocket are as close as I can get to the original control layout.

System Type
- Choose what type of WonderSwan to boot. Changing this option requires resetting the coreCPU Turbo
- Allows the CPU to perform additional processing per frame, which can be used to eliminate some slowdowns.
The WonderSwan has a native refresh rate of 75.4Hz, but the Analogue Pocket doesn't support higher than ~62Hz (and 60Hz on the Dock). This core provides the option to either run the display directly at 60Hz, introducing tearing, or to triple buffer frames at 60Hz, introducing latency and skipping some frames entirely.
Triple Buffer
- Triple buffer image to prevent tearing. Please note that this does increase latency and will cause frames to be dropped.Flickerblend
- Use a combination of 2 or 3 frames of data to perform blending on flickering UI elements. This will decrease the flickering and resolve the flicker into a lighter grey color. Please note that this enables the frame buffer implicitly.Orientation
- Lock the screen rotation to a particular direction. When set toAuto
, the core will automatically rotate the display.Flip Horizontal
- Flips the display whenever the WonderSwan would display in horizontal mode.
Fast Forward
- If enabled, play sound when fast forward is active.
