[Request]Can there be offical archive of the 1.X CS's?

There already is one, it's called YouTube.

Youtube isn't official. Technically speaking, SE could ask any of those people to take it down by claiming intellectual property rights. Will they? Probably not.

But having an option that is in the game would be nice.

I mean they use old 1.0 Cutescene couple of time.

They actually didn't, they only reused parts of the pre-rendered opening movie FMV scene from 1.0 (in the 'opening' FMV for ARR and Gaius's explanation about the Battle of Silvertear when he appears in ARR for the first time). Actual story cutscenes from 1.0 which are rendered in the game engine in real time have never been used (although there are a couple of scenes with similar cues to 1.0 scenes in ARR, but they're not the exact scene or even a copy, they just share ideas and cues between them), because each game has a different engine as I mentioned: 1.0 used Crystal Tools (the same engine used in FFXIII, XIII-2 and Lightning Returns), while ARR uses a custom engine partially derived from FFXV's Luminous Engine (but not literally that one), meaning any real time cutscene used in the former game would have to be completely recoded from the ground up to use new models and features that are used by the current engine (and a lot of the resources and models used by 1.0 don't exist here in ARR).

Given the time, effort and resources needed for such a venture, it's clear SE simply do not consider it worth the effort to do so unfortunately (to say nothing of many of those scenes no longer being effectively canon narrative wise anyway (there are certain story elements in 1.0 that... seem to have been cast aside or even ignored in ARR outright, meaning SE has effectively retconned them - some aspects of 1.0's Gridania story are an example of this).

So again, I'm going to say if you want to view 1.0's cutscenes, Youtube is your only option, as it's apparent that SE simply are not going to add the old scenes to ARR.
