Ah - I don't mean to be making assumptions, but you realize you have to unzip it first right?

Data Disk mode

Alternatively, you can put your Playdate in “data disk” mode without installing the Playdate SDK. This will let you access its filesystem and copy the game file over.

NOTE: It’s possible to break the software on your Playdate by accessing the files on it directly. Please proceed carefully.

There are two ways to do this. One is:

• Attach your Playdate to your computer via USB cable.
• On your Playdate, go to Settings.
• Go to the System section.
• Choose Reboot to Data Disk and confirm.

Alternatively:

• Attach your Playdate to your computer via USB cable.
• On your Playdate, press and hold the following three buttons at the same time: Left, Lock (top edge of your Playdate), and Menu (round button in the top-right corner).
• Hold the three buttons for a few seconds, until the screen reads Sharing DATA segment as USB drive.

Whichever way you used to put your Playdate in data disk mode, do this next:

• On your computer, open the newly mounted PLAYDATE volume.
• Open the Games folder.
• Place the .pdx (not a zip file) into the Games folder.
• Unmount the PLAYDATE volume.
• The game should now be available on your Playdate.
