Bootstrap the NA download using your JP download

If you're like me and your game deleted itself this morning, and you have an old (or even up to date) you can make the download faster by copying the files from your pso2_bin/data folder from the JP version to pso2_bin/data on the NA version. It will have to download some files which are different, but the download is much smaller, just around 10k files.

Just a note, this only works if you have permissions to write to the folder, and make sure to back the files up when you're done.
