Polandyou can't, such addons don't work for versions 2.0.9.1 and older
look at your left-hand side of the screen, select Level Leaderboard, select the campaign you are interested in
Join the L4D2 Speedrunning Discord to get 2.0.0.0 version, it works a lot better than 2.0.0.8 one. Its gonna be avaible in #old_version_downloads chat.
Btw I tried massaging you on Discord first but the one you have on profile doesn't work.
Having experience from moderating other game on sr com, knowledge about Patapon games and will to speedrun it I think that keeping Real Time in that game isn't fair and can have the massive result on the speedrun time at the end. I would like to offer help with creating proper timing rules for Patapon games so the leaderboard is kept as fair as its possible.
No, it will not be "correct" because all of these old version were actual "Steam versions" before and it would be unfair if someone did a speedrun at that time and someone else couldnt beat this time later because the skip got patched. All of the versions released by Valve are allowed to be speedrun on.
