Paper Mario: The Origami King is already being played on PC
Official publication not until Friday.
Nintendo Switch exclusive Paper Mario: The Origami King is already playable on PC via emulator, days before the game's official launch.
Footage of the upcoming adventure role-player running on PC has been posted by several YouTube accounts, which are now uploading whole chunks of the unreleased game (thanks Resetera).
Hacked copies of Nintendo Switch games regularly appear on PC emulators, but the leak of a game yet to officially go on sale is a relatively new headache for Nintendo. The quality of Switch emulation is also improving - in the first video below, the game appears to be running with no technical issues.
To be clear, there's no legal way to play Paper Mario on PC - or any other Nintendo game downloaded from the internet for that matter. Illegally ripping a game's contents and then distributing them online is something which Nintendo has historically got litigious over.
The Origami King is the latest in Nintendo's long line of Paper Mario RPGs, and the only game from the company currently with a release date. After its launch on Friday, Nintendo has no firm dates for any other first-party release on its schedule - though a handful of Mario remasters are not too far away.
