What is the ruling on re-programming and developing old electronic games that have been shut down by their original developers and re-publishing them? Does this affect moral and legal responsibility? And is one sinful if they provide a feature in this game for male and female players to communicate via chat, with rules put in place to prevent inappropriate conversations, or should there be a complete separation between them?

The First Part: Intellectual property rights are protected for their owners, and it is not permissible to infringe upon them. If the game is copyrighted, it is not permissible to modify it in a way that violates copyright. Whether the discontinuation of the game constitutes a waiver of its rights depends on custom, circumstantial evidence, and the experts in the field.

The Second Part: It is imperative to prevent the mixing of genders in playing together due to the potential harms that may arise from such interaction.
