Unlike the version in the Japanese sprite pack, this chain chomp has a real chain movement, like the one in SMB3.
This version fixes a bug that caused the sprite to glitch on the Higan/BSNES emulator. Credit to Kaijyuu for the fix (which he discovered nearly 3 years ago at the time of writing...why did nobody submit it sooner?).
Now SA-1 hybrid, but also incompatible with Wigglers due to the need of a large chunk of RAM for segments. The RAM used can be easily changed via defines.
