I USE SOURCE UNPACK. I WANTED TO SEE THE FULL SCREEN SO I CLICK "FULL SCREEN" IN THE SETTINGS. BUT NOW I CANT CHANGE IT BACK. WHEN I RELOAD AND OPEN SOURCE UNPACK AGAIN, THIS HAPPENS.
You could try editing your Portal.bat in your SourceUnpack file. Just rightclick the file and select "Edit in Notepad". Where it says "start" copy/paste:
hl2.exe -game portal -novid -console -fullscreen -high
Then save Portal.bat and double-click the file to open the game. In the game go to "Options" then "Video" and change the Resolution to whatever is needed, click on "OK" and the game should change resolution without any errors.
Note: When using Fullscreen, LiveSplit won't show on top and you can't see your Splits because of it.
Hope I could help you.
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
