"I got MGA2 USA working. Simply decrypting and replacing the prxs doesn't work. This is what I did. I decrypted the prxs and put them aside. I replaced all of the MGA2 prxs that are also available in swbf2 with the swbf2 files. MGA2 has a couple that were not in swbf2; for these, I used the decrypted MGA2 ones. There are 4 files that do not decrypt using prx decypter and are not in swbf2: kjfs.prx, sound.prx, kjnet.prx, and zlibdec.prx. I left these exactly as they were. Works like a charm so far"
