Moved for ya.
As far as converting, you basically run it through ASH step 1--- copy the folders. Run the other region pac through ASH step 1--- replace with previous folders, run step 2. But... that requires that ya get the files for the other region... most stuff we have up for download is NTSC --- if you need PAL files, you'll probably need to acquire your own ISO (see FAQ).
As for your Project SA... yeah I suppose so. Just open up the file and go.
