I know these are not supported version since they are pretty old, but the problem is not on those versions exactly, because when I simply want to play an older version for a nostalgia session It is so hard to do so because there is absolutely no sound in them, I heard it was some problem with the mojang servers not having those sound files anymore, but I would really love (and plenty of other people to) for this to be fixed so I can properly play on them withouth having to rely on a alternate launcher or having to ocassionally tweak the files myself, life would be so much better this way, I sincerelly hope someone sees this and is able to fix it, It has been a problem for so long, I just want to be able to paly those version normally like the newer ones

Also skins do not work in the same versions, from early alpha and classic to release 1.6.4
