I downgraded to alpha 1.2 or something and made a world in world 1. In my saves folder it has world 1 there but nothing shows up in my 1.4.7 minecraft. I downgraded, because I would like the old generation with the trees and the sand and stuff, with no jungles. Any ideas?
i think this can help. if it does, let me know: i've never tried to de-update my Minecraft, and i don't plan to. but here a is ONE good tip. if it's a tip at all :/ you can play a really outdated version of Minecraft: it's called Minecraft classic. you can find it on Minecraft.net. try it out. because i like it. it's basicly all the old-school stuff.
If you are asking to update your alpha world, then you need to do these things.
1.Update your game to any beta update before 1.8 (1.7.3 would be a good update to go)
2.Play the world. It will then be upgrading it to it's own world format.
3.Now you can update it to 1.4.7. Play the world and it will now transfer it to the Anvil format.
4.Play world and enjoy!
P.S. Make sure to backup the world in case anything goes wrong.
