  • Online Mode.

  • Offline Multiplayer (Hot-Seat).

  • Online Top-10.
  • The playerdata is saved on the server.

  • MOD-player (all credits for the MOD-player go to Deku-Tree).
  • Awesome music from HtheB.

  • DLDI FAT by chism.


Extract the contents of the folder to your FAT-compatible flash card.

Patch the binary with the proper DLDI patch if needed (this shouldn't be necessary for most cards, only patch if it doesn't work).

Blubb uses data/blubb/ for the data by default, this can be changed in the blubb.cfg if you want to.

Online Mode

  • Use this only for LAN-play, or if the blubb-lobby is unreachable.
  • The server has to forward ports 9999 and 10000 to his NDS (not necesarry for LAN-play).
  • The client needs the Servers IP.
  • Games played in direct-connect mode won't be saved on the lobby.

  • The games played on the lobby will be saved.
  • You need at least three games plus one game per week registered on the Lobby (registering is done automatically at first connect).

Works on R4DS Original (firmware 1.19u).



  • Draw-Routine is called in V-Blank now – that should make the drawing fluid regardless of the 3D’s framerate.
  • Included output of SGIP_errno when sending / receiving fails. that might help me bugfixing the communication.
  • Included animated ships (nothing to write home about – the 3d-Designer (me) sucks…)
  • Fixed the slow-down when many “move-markers” where shown (e.g. moving the green ship) – the game should run constantly at 60 FPS now.
