Some Wonderswan related Projects and Links:

Somewhat up to date (2015):

• WonderMadeleine
  Project that reverse enginered the memory controller put on each WonderSwan Card.
• Flashmasta - WonderSwan Color Flashcard
  Flavor is trying to do an WSC Flashcard. ZOMFG UPDATE He did it! The WS Flashcard is available!
• Oswan for opendingux
  Since Cygne and its successor O-Swan never had been made open source this got my attention. It is a leak? Code piracy? I jet have to find out.
• Liranuna's DualSwan
  WSC Emulator made for the NintendoDS. He made this emu from scatch and I think thats why it worths a look.
