To any of those unsusccessfully trying to download Skyblock 1.0 to 2.1, kindly refer to page 283, where Noobcrew has posted new MediaFire download links to almost all versions.
Now, the astute reader might have noticed the word 'almost' in front of 'all'. I didn't just place it there as decoration, for there do not seem to be any (working) download links to the first versions of Skyblock 1.0 and 1.1, found under the spoiler 'old downloads' within the original post.
If there is anybody who knows where these can be obtained, do kindly let me know, as I should love to try out the very first iteration of this classic survival map in Beta 1.7.3.
Thank you for your reply. Though mine might be a bit late, I do think that, for the sake of clarity, I ought to point out that I am afraid there might have been a misunderstanding. By the 'first versions' of Skyblock 1.0 and 1.1, I did not mean the ones provided by the MediaFire links - those are the 'second versions'.
The first versions of 1.0 and 1.1 both contained sand as a central layer of the island, and appear to have originally been designed for Minecraft Beta 1.7.3 at the latest, judging by the look of the chest. You can find the pictures under the third spoiler in the long section comprised of the same at the end of the original post. Unfortunately, the only available links appear to be the broken AdFly-links.
Thank you for suggesting browsing other sites, such as minecraftmaps.com. Unfortunately, neither this nor skyblock.net, which I have also tried, contain download links to the versions in question.
As I stated in my previous post, I should appreciate it if anybody could point me in the right direction towards obtaining these files.
Why dont you post those Mediafire link on your OP and maybe stop people from having to try and use the clickfest malicious infested adfly links that are still on there. Its not cool man cos a lot of those sites ask you to open your PC to this and that, not very responsible or public spirited aye.
