While every single one of the old dubs is available on japan dvd except for kiki, including the old dub for castle of cagliostro. None have been carried over to the blu ray.
The Japan blu ray for cagliostro has no dub or subtitle. The Europe releases are all the new dub and probably the dubtitles.
I wish i could watch the blu rays with the older dubs but that is not going to happen.
The so called JAL mamo dub apparently was an in house dub by TOHO, the same people who did the godzilla dubs that are not currently available right?
