Where can I find old versions of MCEdit? I mean the ones for Alpha and Beta. I've seen some of the old ones can also be used to convert Classic .mine saves to newer versions. I still have some old .mine save files from 2010-2011.

Can we stick a fork in this and call it done? There's been no news in over a year, I would say she is dead Jim.

Hi!

I'm super excited to tell you that I've been trying to do exactly that for years now, and tonight I've finally managed to do it. So! Here's what I did:

1. Download the oldest available version of MCEdit (you can go through all of MCEdit's versions on GitHub here, or you can skip to the oldest one here)
2. Run the program (you don't even have to install it if you don't want to, just leave it in your Downloads folder)
3. In MCEdit, click Open World and navigate to your .mine file to open
4. Once you open the .mine file, you can click and drag to select areas (or click the MCEdit menu in the top left and hit Select All)
5. On the left side of the screen you can select Copy and then Export to save this world somewhere as a schematic
6. Still within MCEdit, create a new world (or load one you want to add your old .mine world to)
7. Once it's open, click the Import icon (along the bottom of the screen) and navigate to wherever you saved the schematic
8. Import the schematic, place it somewhere on your map, click Save under the MCEdit menu, and you're good to go!
9. Open Minecraft (this version of MCEdit exports worlds for Minecraft 1.8) and you can now play!!

I hope this goes wonderfully for you and you enjoy it as much as I have. It's only been a literal decade... Safe to say my nostalgia is really intense tonight :') Happy gaming and let me know if you have any questions!!

You can find even older versions of MCEdit here; I still use 0.1.7.1, the last stable release from CodeWarrior, the original creator (there's also a newer "dev" version which may or may not be fully functional):

https://bitbucket.org/codewarrior0/mcedit/downloads/

Notably, even 0.1.7.1 can load worlds from versions as new as 1.12; it just has issues with editing tile entities and items, though those don't matter since I play on 1.6.4, thus I've never bothered updating MCEdit (it is also important to note that 1.8 changed the way items are saved and if newer versions of MCEdit do not account for this you must not use them to edit items, though copying e.g. chests seems to work):

Is there a way how I can convert my world from beta 1.3 to beta 1.2_02?

To the developer of MCEdit, I have the following feature request:

Please re-add the ability to edit legacy MC worlds (those before the Anvil update).

Also, please add the ability to import raw data for a region (it should interpret any file who's size is 67108864 bytes) as being valid region data and replace the current region data for the currently loaded region with this imported region data. For editing a region in a legacy MC world (MCR files instead of MCA files) it should consider any file who's size is exactly 33554432 bytes as being a valid region raw data file and import it (if a legacy world is loaded in MCedit).

Also, any file who's size is exactly 65536 bytes, this should be treated as a valid chunk (not region) raw data file and imported into the current chunk, for current version MC worlds. Likewise any file who's size is exactly 32768 bytes should be treated as a valid chunk for legacy MC worlds, and successfully imported into the current chunk (if a legacy world is loaded in MCedit).

Also for each of the imports I described above, there should be a corresponding export.

MCEdit is long dead; the last update was 4 years ago, 2 1/2 if you count a developmental version:

https://www.mcedit-unified.net/ (Jan 24, 2017)

https://www.mcedit.net/downloads.html (August 14, 2018; this version was to be a successor to the original but never got out of beta and the front page only says it supports 1.7-1.11, though I assume it works down to 1.2)

Also, 32/64 KB is not enough data to represent an entire chunk unless it is compressed, only block IDs and only 256 at that (16x16x256 = 65536); 4096 block ID support (only fully supported by mods) would add another 16/32 KB and metadata would also add 16/32 KB for a maximum size of 64/128 KB (the game also saves light data but MCEdit can recompute it at the expense of the time required) and all bets are off for the 1.13+ chunk format (the changes in 1.13 are why MCEdit was abandoned as it was just too much work to refactor the code, any successors are unlikely to support pre-1.13 versions for the same reason).

It is also quite unfeasible to use raw (uncompressed data); a region would be 64-128 MB compared to as little as 4 MB for an actual save file (including lighting and other data, which shows just how well compression works on chunk data; assuming an average depth of 6 sections my first world has about 7 GB of uncompressed data compressed into 583 MB of region files, a ratio of 12:1. This also understates the compression since compressed chunk data is aligned to multiples of 4 KB, which is why an empty "void" world still takes up 4 MB per region, but becomes much smaller when compressed in its entirety, and my worlds are larger than usual due to all the caves I lit up, increasing the complexity of the data).

That said, you can still download older versions of MCEdit here (these are the true original version, made by codewarrior), although I don't know when they dropped support for pre-Anvil worlds; the version I still use is 0.1.7.1, the latest release version (I originally downloaded it back in 2013 when it was the latest release and never bothered upgrading due to lack of need; it actually can load worlds from versions as new as 1.12 despite not recognizing new blocks):
