Unlike the Game Boy, there are very few flashers/dumpers for the WonderSwan.

  • GameBank used to make a WS adapter for their retro dumper, but it has since been discontinued and removed from their page.
  • Sanni's Cartreader can dump WS cartridges using a custom adapter. It requires salvaging of a cart reader slot from a WonderSwan console (the Save the Hero version of the Sanni dumper has adapters planned for the WonderSwan).
  • A manual dumping guide exists, but it is an advanced project.
