SA-SRB2 is a modification made by BlazeHedgehog that emulates the style of the Sonic Adventure games in SRB2. To this end, it utilizes Adventure Mode, a feature in old versions of SRB2 that changes Sonic's ability to the homing attack, gives players the ability to light dash and enables analog control. On top of this, it features many custom sounds and graphics, including textures that were later added to SRB2 itself, several custom SOCs and OpenGL-only lighting effects. Some of SRB2's levels were modified as well; in particular, Greenflower Zone Act 1 received a new ending area and Greenflower Zone Act 2 received a new starting area and was modified to play in reverse. An SA-SRB2 version of Deep Sea Zone as well as an Adventure Field map called Mystic Ruins Zone were also developed, but never finished. The original version of SA-SRB2 was released for Version 1.08, but a later version is compatible with Version 1.09.4.
