Pokemon White 2 freezes

[pikachu]

Hey!

My problem is, that in certain situations Pokemon White 2 freezes or hangs. I'm currently at the beginning, on route 20. There is a pokeball in the grass and when I tap A to open it everything freezes and I have to load a previous savestate. The second and more annoying issue is, that everytime I have to fight the attacks don't show up. It does not freeze, but I can't continue anyway, because I cannot escape either. At the very beginning everything worked, but suddenly fighting was not possible anymore. I already tried several cheat codes, that should fix some issues (e.g. Exp) but none of it worked.

I hope that anyone can help me, thank you in advance for your efforts!

Update: Apparently the game freezes everytime someone wants to talk to me, when I try to pick up any item and at specific places in the high grass. I don't know if it happens only on route 20, because I actually cannot go anywhere else. As I mentioned above, everything worked fine in the beginning on route 18.

Update 2: Look's like the drastic-savestate causes the freezing and hanging. I just loaded the ingame savestate and everything is working beautifully! However, I would be pleased if there is a solution for this issue, saving ingame is a bit more impractical than saving in drastic.

Update 3: Turns out that there are still problems, everytime I want to leave the "pokemon" menu to see my current team and change positions, the game freezes; furthermore attacks don't show up in a fight sometimes. I hope that someone will join this monologue soon

Update 4: There are two patch-cheat-codes which fix the "freeze-while-exiting-pokemon-menu-issue". Unfortunately it's apparently not possible to copy codes from drastic, so you have to try it out which codes work. The issue, where the attacks don't show up seems to be gone now too, although this is can not be caused by the cheatcodes, because I had this problem also afterwards. So everything is working pretty well for me now
