Zone of Enders 4.21 fix.

I have been seeing a lot of people having problems getting the Zone of Enders HD pack working on 4.21 cfw. The same thing kept happening to me too. The game would load fine and the intro would play but when you would try to play either of the games it would go to back to the XMB. Re-signing the BIN's didn't seem to work.
All I ended up doing is checking the BD-Mirror radio button for the game in multiMan and hey what do you know, it worked. It is also located on the internal drive too. I figured there was some obscure sprx fix I had to do since the game started out working fine and then crashed.
I guess you wouldn't call this much of a fix as much as a common modification to loading the game. The only reason I thought I would post this is because of how often I have been seeing people complaining of the same crash. I stumbled upon this by accident when I was loading the JAP version of One Piece a month after Rebug 4.21 came out.
Anyway hope this helps someone.

Edit: I have gotten a couple PM's asking how I got this fixed. I should not have bogged down the message so much and just put the fix.
1. Copy to internal (It may work on external, dunno)
2. Press square (or triangle) and go to the game options and dot the BD-Mirror and Internal radio buttons.
3. Play.

I did notice some lag here and there when I would pause/un-pause but this is nothing compared to the lag and chunking on the 3.55 fixed versions.
