EDIT: This is now working for the second patch (and hopefully all future patches. Will make the description more coherent later)
The quick version:
1. Installed Starcraft II Beta from http://thepiratebay.org/torrent/5371903/Starcraft_2_Beta_Client_US_Build_13891
2. Ran to get the latest patch
3. Downloaded the loader. (Did not run it at this point though it shouldn't matter) http://www.mediafire.com/?mon3ntwhit2
4. Downloaded the mappack from http://www.multiupload.com/7YY40566LH
5. Downloaded the replay enabler from http://www.mediafire.com/?xlmmwncw2ow
6. Ran the replay enabler it installed.
7. Downloaded the V4 AI http://x.00.dy.fi/sc2c/StarCrack%20AI%204.0.rar
Installed according to instructions.
8. Created the folder C:\Users\USER_NAME\AppData\Local\Blizzard Entertainment\Battle.net\Cache\00\11 (just need to make the 11)
9. Copied the maps from the map pack (after extracting) to the folder I had just named. Renamed them putting 0011 in front of each map (letting the rest be, so for example one map was named 0011(2) - Blistering Sands.s2ma (remember to launch the game using these maps, the one under the Cache\00\11 folder)
10. Enjoyed (I could view the replays launching starcraft regularly or pressing leave game after launching a game. The replays were under recent and worked perfectly)
*Edit: I really need to make this clearly and hopefully can upload a file with a bunch of different AI later today.
Thanks to marlow, just a note: Ok here is the fix to load latest replays :
Just need to download an updated cache folder (here : http://www.sc2win.com/starcraft-2-downloads/starcraft-2-cache-files-update/ )
Don't forget to put the original Base.SC2Data... et voilą
The OLD longer version:
This is a short tutorial on how to view the replays you've played against the AI. I assume for the sake of this tutorial that you have installed the hack that lets you view replays in general. (Otherwise check out Link will go here).
I recommend (but not needed) that you have the harder (cheating) version of the AI installed as your games will be more fun, but by no means is it necessary.
You will need some maps with the AI enabled on them. A great map pack you can download can be found at http://www.multiupload.com/7YY40566LH
Now once you have the maps go to C:\Users\USER_NAME\AppData\Local\Blizzard Entertainment\Battle.net\Cache (For Windows 7 and Vista users). In general just find the AppData folder and open local then blizzard entertainment... It should not be to difficult to find.
In the cache folder you should see a long list of folders named with just to characters. Your next step is to create two folders (or use some that are already there) to put your maps in. This is what I did to be able to find my maps the easiest, but you can do it with any four charcters:
In the Cache folder I opened the 00 folder (you can create one if you don't have one)
Then inside of it I created a folder called 11. Inside of that folder I pasted all of my maps. Now after pasting the maps you have to put 0011 infront of all of the maps names (but you can leave the rest so that you can see what each map is). Now when you use lazy launch just open up C:\Users\USER_NAME\AppData\Local\Blizzard Entertainment\Battle.net\Cache\00\11 (or you equivilant) and select the map you want to play. The next time you launch LazyLaunch you won't have to find the directory as LazyLaunch saves the last directory you were in.
Now just play like you would regularly and enjoy
. Now whenever you want to view a replay just find it like you would regularly under recent and viola! it will launch. Feel free to post any cool replays (or questions) in this thread for others to see. (if you do not use the default 00 then 11 we will have to place our maps in the folders you chose, so please stick to the default if your going to post replays).
(I will be editing this guide and it is a little unclear and the spelling sucks)
