Sonic Advance 2 - Lower SP Ring Requirement is a modified version of Sonic Advance 2, changing a specific gameplay element, the number of rings needed to maintain the Special (SP) meter. This likely originates from a ROM hack or fan-made alteration, focusing on a specific gameplay tweak without potentially changing other elements of the original.
