Hi Circo and welcome aboard

You should contact some of the guys currently leading TOSEC ISO part. Since idoru is MIA for some time now i would recommend you contact Ripper006 or Maddog, you can find the first here so just send him a PM.
Also, i'm not working with the iso part but i think toseciso dreamcast dumps are made by the
dumpcast, if the above plan fails you might try to contact them too.
Good luck and keep us informed, anything just ask
