Love this. I do wonder how the bug fixes will affect speedrun attempts, and if people will start using this for speedrunning or if they'll stay on the prior version.
The Steam version is basically dead; WON is what most runners play. (Though it would be interesting if this revitalized the Steam categories.)
For those curious, you can download WON from https://www.speedrun.com/hl1/resources ("GoldSrc Package" and "Half-Life 2005 Package" are the builds allowed in the WON categories). You will need Half-Life on Steam to run them (which is currently free until Nov 20 - get it while you can).
