I recently made a "minecraft usb" that allows me to play minecraft on both a windows, and a mac machine (my main machine.) The root directory has two folders, "MC_MAC" and "MC_WIN". Everything works great, but I'm looking for a way to make the two installations use the same "saves" file, so that I don't have to keep copying and recopying worlds from the Mac "saves" to the "windows" saves.
I thought of using the "Alias" function on mac, but that probably wouldn't translate well onto a windows machine.
(Bonus points for getting the one "source" file to sync with the saves file on my mac when I plug in the usb...)
So far, I've got answers about how to run minecraft completely off a USB. This isn't my problem, I've gotten the game to work fine on both mac and windows, running completely off my 16GB Flash-drive, and leaving no trace (so far as I can tell) on the host machine, be it windows or mac.
Seeing as the MC for mac is a .app and MC for windows is a .exe, I can't use one install on both computers. And seeing as I have two installs, with each one generating it's own set of files, I have two save folders.
What I need is some way to make both installs read from and write to just one save folder.
