I launched the steam version of portal to test an idea I had, but shortly closed it. I went to the Source Unpack to do some runs, but when I tried save glitching, it didn't work, so I checked the version, and and it said 5135 (Steampipe) although it should've said 4034 (i think so), i launched 3420 and it was on build 3420, but Source Unpack just went to the Steampipe.
source unpack is build 5135, you likely just did whatever saveglitch incorrectly. 4034 isn't a real build of portal.
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
