There are lots of cool things like this to discover in Sega Saturn games, in large part because people are intimidated by the notoriously difficult SH-2 assembly language. However, the Saturn surprisingly has really good tools for reverse engineering. There is a very good save state loader for Ghidra, and the Mednafen debugger allows for on-the-fly memory editing. With these methods I also found a cheat code for Clockwork Knight 2 that grants access to the entire first game! Somehow that was secret for decades.
