armoured core silent lines portable

I tried playing it but it had anti piracy. My psp is running on 5.00 m33-6 CFW. Help, please?

If you want to play new games, you will want to update to 5.50 GEN D3. It really isn't that much different than 5.00M33 in terms of how it runs. And I'm pretty sure it runs Armored Core without any patches needed.

I have no idea how to update, plus I'm on a mac. Someone else hacked it for me.

You just need to put the updates on your PSP and run them like you do a game.
