It's funny because custom electronics are way more cheap and accessible than they used to be. In the 90s, I wished I could dump my game carts and saves. I saw someone posted PCBs to do it over ISA bus but I didn't have the skills or ability to do it myself. Recently, I found this open project that can dump that era: https://github.com/sanni/cartreader
