Before to start, I apologize for my poor English. I'm Italian.
Today I found my old cartridge of Pokémon Diamond.
Back in 2007 I was a kid and a friend of mine convinced me to use the Action Replay. I used a lot of codes to find shiny Pokémon in the grass and much more.
Now, when I scroll down the Pokédex my game freezes on Rhydon.
So, with Savegame Manager tool I ported my save file to my PC and tryed it with the Emulator (No$Gba).
The game doesn't freeze on Rhydon but then on Chansey this appears:
Then also with Kangaskhan, Jynx and Tauros.
Is there a way to fix this problem?
I attached my save file if you would like to find more. It's from the Italian version of the game.
