• Fix spelling text of no game & no app pop-up message.
• Deleted color GUI option.

#General:

• Implemented a new NVM system to save the user configuration on the non-volatile storage.

TODO:

This is a list of issues that are known issues and will be revised:

• Some games didn't open due to the name. Those names don't have any special character or are too big a size.
  Temporary solution: Change the name for something simple but not changing the extension of the file.

• Some GameBoy Color games with a size bigger than 3MB don't run. This issue is due to a lack of space on RAM. It's required a reorganization of the software to free more space.
