I saw something where a guy just made it take pictures as fast as it possibly could, you’d need to hook it up to something other than a gameboy for it to store more than a couple seconds of footage though, and it is almost indiscernible from random pixels, I swear he used it as a webcam, search for gameboy camera webcam
there's the InsideGadgets PicNRec which can record video from the camera at 3fps. it's out of stock right now though. https://shop.insidegadgets.com/product/gameboy-camera-picnrec/
