WS Flash Masta USB (Cartridge for WonderSwan)


NOTE!  We have these built, but they need some testing before we can ship them out.  During the holiday season, we may not get to do this in a timely manner.

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.
