Yeah that's pretty much it. Carts aren't an issue it's just a matter of tracing the connections and convert the LCD images, that blob will definitely need a decap. Do you have any idea of what's hiding behind the blob?
If you are willing to sacrifice one that would be great Rik, all I have is 1 cart (Submarine). How many of the games do you own? Beasts Planet seems to be kinda rare.
