Revive Aeris/Play with Sephiroth Codes

Hallo alle. I started using CEP to have some extra fun with FF7 today, and like any decent FF fan I am trying to find a way to revive Aeris and have Sephiroth (maybe not at the same time).

I have found several sources giving this method using a Gameshark. (Same process, different code for Sephiroth)

However, these do not work. I have used alot of other codes today, so I know there is nothing wrong with my game or CEP. I'm just wondering if these codes only work on an actual PSX with gameshark, since I can't explain why they wouldn't otherwise.

Those codes work fine with PEC and real hardware, you do need the correct region game though

The game will crash though there are lots of battles and cuts screnes (not FMV) that will crash having Aerith (After she goes) or Sephiroth or Young Cloud in your team (<- those two will crash the game most the time), same goes for the parts that are ment to have Sephiroth will crash if you change the team members

So although it sounds cool to have Sephiroth the game will only crash out most the time (If I remember thats all battles aswell) if you remember the flash backs you don't get the control Seph anyway
