A glitch has been found on Lumiose City. Don't save your game at Lumiose City or your game will be corrupted. Don't want that or you have to save (or it is urgent)? Here are some places that you can save:
Pokemon Center
City Buildings.
Nintendo is working for an update. Till then, don't save your game in Lumiose City.

Cure of Glitch:
Two weeks ago, Nintendo released Pokémon X and Y simultaneously across the globe. Unfortunately though, some users experienced a glitch when they saved their games in Lumiose City's various Avenues, where the game's controls would be unresponsive upon loading a save file, leaving the only course of action to be to delete a save file. Nintendo was quick to acknowledge the issue and released a map of where it is safe and where it isn't safe to save without risking setting off the glitch while promising that a more permanent solution, a software patch, was in the works.
Today, Nintendo has released that patch worldwide. A 227 block update for each version is available for free from the Nintendo eShop digital store. If a copy of either game is in your console at the time of accessing the eShop (either with the Game Card in the slot, or a digital copy on an SD card) you will automatically be prompted to download the update. As well as fixing the infamous Lumiose City glitch, this patch also fixes a minor GTS bug where using a filter may have resulted in an error message.

Yeah. How many pokies did you get for that??
Anyways, I think it's foolish to upgrade the game for 227 blocks. Nintendo made the mistake and they are taking blocks for the upgrade

Hey you people, do you have any emulator to play pokemon x .

Unfortunately, nope.

We are always active to find it.
If we find one, we will tell you for sure.

Yes.
