listdemo+ but more. Has checkpoint detection, options like cheat/jump detection, and verbose demo dumping. If none of that made sense to you, just download listdemo+, it's probably more stable. (external link)

These should be the most optimal saves for challenge mode. (direct download)

This is for Least Steps challenge mode. If you save late you can't shoot both portals because of the portal gun reload time. These saves were made early enough to make a 0 step elevator exit possible. I made these saves so you don't have to. (direct download)

NOT recommended for new runners. An earlier build of the game with free out-of-bounds movement, useful for advanced tricks like 02 skip; First found by Avetixz as far as I know, cleaned up and reuploaded for public consumption by myself, with a couple of nice extras like borderless window support and raw input. NOTE: You must own the game on Steam to play this version! (external link)
