You mean regular SRB2 or SRB2Kart 1.x? SRB2 maps cannot be loaded in DRRR, and DRRR is not backwards compatible with SRB2Kart Mods because they are old and DRRR use new engines and features and textures in mods... Including Maps. So trying to load an SRB2Kart Mod in DRRR will either crash the game or not work at all. So bear that in mind. A section of DRRR MODS in this Message Board will be added soon. Stay Tuned!
