Hm, that's not the latest build label iirc. Did you install the game via steam? Is this copy legitimate?
nahh thats crack
no judgement but i don't think anyone here can really help in that regard lol. just buy Portal, it's like $1 right now for the autumn sale.
ask a friend to gift it to you then or something lol. speedruns are usually done on Source Unpack anyways which requires you to own the game on steam (AFAICT, I imagine it's probably crackable but I'm not gonna bother since it's easier to just own the game honestly) so you're kinda out of luck if you're looking to actually speedrun
Build label 1910503 signifies the 2013 version, integrating steampipe and switching to the Source 2013 engine branch. From its release until March 2022, this version was on steam. Notably, this build alters portal bump properties, making some glitches more challenging and some methods unusable. Quicksaving on this version causes a distinct stutter, rectified in the March 2022 version and not present in other iterations.
Starting now and currently being grandfathered, all console runs will be manually retimed with load times removed. This process will be redone by the verification team anyway, so don't worry about doing it yourself when submitting. Massive shoutouts to Tactix1 for doing this basically single handedl
