I've created a PSP homebrew using augmented reality.
the first step, called Area 0, is most of all a proof of concept.
But, you will aim to uncover the region's mysteries.
So, download Region X Area 0,
Print one of makers provided in the folder named "imprimables".
patt0_1500 is the most appropriate to do movements near the marker.
Although you'd better use the patt0_1800 for better result futher from the marker.
In a well-lighted place, connect your Go!Cam and launch the homebrew.
Left and Right : Move on the main menu.
Cross : select or unselect object.
Circle : return to main menu.
