I don't know about Godzilla dubs, but iirc, they (Toho) were responsible for that awful Macross Do You Remember Love dub (no, not Clash of the Bionoids hacked version, also by Toho, but the whole film has a dub, last available on LD, from my understanding, other than fan discs which added it to the DVDs and BDs); the awful dub which featured Hong Kong natives as part of an English as a second language learning practice mixed with some Aussies for good measure. Only for watching out of curiosity, imo. Or to get drunk to, and similar fun.

that said, I kind of like the JAL/Toho Mamo dub. I only wish that there were better versions available. The only full length versions are fan capped VHS tapes from decades ago, many Nth generation. The dub was released on Italian DVDs, but an edited version missing about (iirc) 30 minutes. I have the ITA disc and the edits are pretty bad and make the movie kind of a disaster. Now I have been reminded that the Discotek version of the JAL dub is coming from a fan who is sourcing the base from the ITA DVD, and the remaining ~30 minutes from the best-known fan preservation.

If I ever can get some HDD space (or better yet, a new HDD) I will be adding these old dubs from many of these to BDs and DVDs. I have access to using Scenarist SD and Scenarist BD, so they will certainly be compliant-spec discs. The HDD space is a killer, tho :/

Cagliostro BD with both Eng dubs/subs (maybe other dubs, subs), and Mamo BD (all 4 English, maybe other dubs +subs, depending on bitrate) are definitely among those custom projects on my backburner (waiting for a HDD), along with Totoro. Kiki I do not yet have the BD... and the splicing/timestretching/pitch correction needed for the only cap we have for the Streamline dub is daunting (though I think timetrtching will fix many timing issues).

Right now I am working on an easier sub/dub BD project, since I already have the subs timed for 23.976, dub is synced for the R2J custom I did (R2J has same master as BD, and I rechecked in Vegas and the sync is perfect). I just have to re-style subs and do more fancy effects for the BD, and then render them. But this is hardly some older VHS/LD dub, so kind of more OT than I need to get in to here.
