My Pokemon games has been acting up...

Well last month my friend and I were look at my Combusken's stats in Sapphire and well we picked to looked at them and suddenly my Mightyena and Sableye were gone and the game froze and Combusken was now a Torchic but I was sure as it was months before playing the game I was convinced I had a Mudkip,Sableye and Mightyena.

And recently I was playing it and for some weird reason instead of battling Shelly I was battling Courtney but the text was mucked up as when I beat "Courtney" it flashed between Shelly,Courtney,Maxie,Archie,Tabitha,Matt and then once again Shelly's sprites in that order!So I turned it off but the amount won was 9999999 so I knew something was wrong and it was normal but it said I beat her!So I now had a Castform and I went out went up against May and I never stood a fricken chance!Her Pokemon were all level 100 and what was even scarier was the fact she had Groudon,Kyogre,Rayquaza,Regice,Regirock and Registeel and they were all to my suprise silhouettes!So I shut the game off and oddly enough instead of the internal battery has run dry message it just said the game can be played 6 times and said the internal battery message then the game can be played right after and creepy thing was I was now May!And I was still to battle May and not Brendon!

Also this is pretty strange I was play Diamond and I wanted some repel and I could afford 99 so I bought some and it cost me nothing!And the money I had was now 0!

I think my games are super fucked up!

In Black some of my Pokemon like my Chikorita now had no ability my Groudon is now shiny and has no such ability and my Arceus,Mewtwo and Deoxys have crazed moves!Like Giga Drain and Horn Drill or Hydro Cannon!And when I walked into White Forest once it was Black City!!!!

And when I connected my Black and White with Feeling Check it said on Black:
75% Travelling Partners
Then a white box popped up with a sad face then saying "Misty hasn't been nice to Aura..."

Once I was playing Emerald befo
