Mortal Kombat X Iso Highly Compressed Instant

I need to provide accurate information without endorsing piracy. Let's outline the key points: what an ISO is, the high compression part, legal vs pirated content, where to get the game legally, and the risks involved with pirated downloads. Also, maybe address the technical aspects of compressing ISOs, like using tools such as 7-Zip or WinRAR, but again, emphasize legality.
