Hm, interesting. Long time ago, I intentionally tried cracking games to detect anti-piracy methods, and Donkey Kong Countrty 2 was one of those, and I triggered the empty SRAM check while doing so (and added that to the TCRF page). I checked the game with more SRAM than the cartridge normally has, and... nothing??? Checking that is a very typical routine in SNES games, and yet... I simply assumed due to that it's the only check, and an incompetent one at that -- first, it would be more evil to let the game continue with no save RAM only for saves to not work, second, why not check for more RAM. But then it turns out there are actually were more anti-piracy methods, and they are quite evil. Wow. I'm not surprised I did not find those considering how those worked however, I had no reason to change the ROM to add a crack intro.
