will i be able to update minecraft to 1.3 tomorrow and still play on EMC? please tell me i need to know!
No, you have to wait until you get the 'Okay, go ahead and update' message on the website. This will be on the homepage.
No. The server needs to upgrade first, which could take a week to happen. However, you can still upgrade to 1.3 but remember to go to your run, type in appdata, press enter, go to roaming and then .minecraft, click on the bin folder and copy+paste the 1.2.5 jar file to somewhere safe, like a folder in the desktop...Or just somewhere you'll remember where it is
1.3 is scheduled for release on 1 August. Some time after that, EMC will be updated, and allow people to use 1.3. But you need to check for announcements on the forum. Do not upgrade until you've seen instructions from EMC. (Unless you really know what you're doing, and run multiple versions) (And yes, I'm repeating the same thing...in the hope others might notice)
Go to the homepage- The First Big Message by JustinGuy- will/ should answer all of your questions. It was bumped up again about half a week ago
You're not copying the .minecraft folder, just create a backup of the minecraft.jar file. By doing this, you can update to 1.3, but if you want to play on EMC you can just copy that backup in.
