A new challenge! Similar to the first Other Castle this tries to give you fun new levels to sink your teeth into. The game saves your progress and you can continue at any point. Check out the manual for additional hints if you get stuck. Have fun!
You need to patch a unheadered USA ROM version of the game. I would recommand this tool to patch. https://romhacks.org/utilities/floating-ips-utility/
