Digital Series One "unlock" cards for Pixel Pup

These are digital e-reader cards that will unlock the e-reader puzzles in Pixel Pup when played in an emulator such as mGBA. Download seriesOneUnlockCards.zip, unzip the bundle, then use them in mGBA (or another emulator) as explained by the Pixel Pup e-reader page.

Are these the full Series One games?

No, these are simple "stub" cards that will fool Pixel Pup into thinking they are the real Series One cards. These cards can only be used to unlock the e-reader puzzles in Pixel Pup. If you try to run these cards on their own, you will find they don't work.
