Notes

  • dipsw1=1 in segatools.ini, same as every other ALLS title, or the game hangs on "checking distribution server".
  • The amAppImageInit(). ErrCode -5 error means your amfs path is too long — newer AM daemon builds require the full path (C:\Games\SDDT\amfs) to be under 16 characters. This bites SDDT specifically because the code is 4 chars and people name the folder after the game.
  • If you keep games on E:\, subst X: "E:\Games\SDDT\" and launch from the drive letter. This is the "segatools issue" in the SEGAguide FAQ: games installed on a non-C drive launch with errors for no clear reason.
  • AquaDX/AquaMai mods apply here — see Resources.
