WS Flash Masta USB (Cartridge for WonderSwan)


International Customers: Please scroll way down and read the “International Shipping Note” below.

Use the WS Flash Masta USB to upload files from your computer to the cartridge via built-in micro USB and play them on your WonderSwan, WonderSwan Color, or SwanCrystal console.

Due to variations in 3D printing, the shell or dust cover that you receive may not look exactly like the photos shown here.

We are currently offering a “Repaired PCB” option at a reduced price.  These PCBs have a minor repair wire applied to them.  They function the same, but you may need to exercise extra caution (to not damage the wire) if you intend to open the shell for any reason.

Please read the full description for important information.
