For different versions of the same game, or alternate editions of a game, there are many factors in play for deciding if obsoleting a published movie or creating a new branch. The most important ones are movie contents and audience reception.
In my opinion, a Yellow no-save-corruption submission that uses a glitch not available in Red/Blue, should not obsolete the current
Blue "warp glitch" publication, but be published as a new branch. However, this is just my opinion, as there would need opinions from more Judges and from the audience. I really can't be sure beforehand about how complex the decision could be.
For what concerns the language versions: using a Japan version of a game is
allowed by our rules, but note that the new movie will be accepted only if it features actual gameplay improvements, and not just being faster due to Japanese text being more compact.
In any case, the current
Red save glitch publication counts as fastest completion, so it could be obsoleted by a submission with low entertaining; instead, the additional branches require to meet the entertaining standards of the Moons tier.
In that regard, I'm pretty confident that using the Japan version would be a problem for the
blank label/no memory corruption branch as, in my opinion, the Japanese language would make that kind of movie unlikely to be enjoyed by non-Japanese people.
For the
"warp glitch"/no save corruption branch I'm not sure.
