About Hacked Main Pokèmon Versions for Handhelds

Do you believe that there are hacked versions of the main series of Pokèmon games for the handhelds?
The official names of the main Pokèmon games for the handhelds (not the spin-offs) are (in English):

• Red
• Blue
• Green
• Yellow
  
• Gold
• Silver
• Crystal
• Ruby
• Sapphire
• Emerald
• FireRed
• LeafGreen
• Diamond
• Pearl
• Platinum
• HeartGold
• SoulSilver

If your Pokèmon game that would like to play has a different title from those above, then that game is a hacked version. Hacked Pokèmon versions are easy to detect because of the previous sentence. These games are not licensed and/or sponsored by Nintendo because they are fan-created versions of the main Pokèmon series of video games for the handhelds.
Please be honest and patient if you try a Pokèmon game, hacked versions may contain more bugs than theire base games.
