toseciso.org is dead.
Unfortunately, because none of the participants of the TOSEC-ISO ‘branch’ are properly active here, we (the main TOSEC project) can’t give you a very informed answer as to it’s current status.
Maybe someone from TOSEC-ISO can give you more info, or hopefully we can offer a proper statement re TOSEC-ISO soon.
CUE files are available in our release packs which can be found in the downloads section of the website.
