Hello, everyone!
Yesterday I managed to take some screenshots the hard way, using a logic analyzer to sniff the data bus going to the Game Boy LCD. It has been done many a time before but was a fun challenge for me. I photographed and documented the process and wrote a little program that takes the exported data from Saleae's Logic Software to generates a screenshot.
In the picture above you can see a photograph of my Game Boy screen (to the left) compared with the final screenshot (to the right) constructed from the data I captured using my logic analyzer.
I hope this will help someone else like me, who are just getting started with the hardware side of Game Boy.

Cool stuff. 50 MS/s seems like way overkill. I don't know if you're planning for a streaming version, but if so you may want to choose a lower rate.

Yes, you're absolutely right. It's just me being lazy and leaving the default setting. Saleae recommends at least 4× oversampling for digital signals so 16 MS/s should be enough for capturing the pixel clock at 4 MHz.
