I do this as well but with a slightly cheaper solution. You can find a used SNES, Super Gameboy, and Gameboy Camera for a reasonable price on Ebay if you look around and are willing to do some minor cleanup and repairs. If you're fine with a bit of analog noise, you can capture it with a cheap composite -> USB ADC you can find on Amazon for under $10.

As an aside, I also do photography with the Gameboy Camera. A company called Epilogue makes the Operator, a USB device for dumping Gameboy carts. It has native Gameboy Camera support, allowing you to dump pixel-perfect pngs of your on-cart shots. The 2-bit dithering is lovely.

Wiring the stuff to do it yourself isn't the worst in the world. When the pandemic started and I was cloistered inside and cabin-feverish, I found a blog post that had a link to the following: https://github.com/Dhole/gb-link-stm32f411 and I bought a board to run that code on. I wasn't able to figure out how to actually write out the raw data as a png so I wrote a script to take the data and convert them to pngs myself. Now that the operator exists (I don't think it did in 2020) that'd be the solution I'd use, but failing that, there's always the microcontroller route.
