My friend (Achilles) found a way of entering the opening demo scenes using the reset feature on the SRT. All you have to do is wait for the screen to go black with the text on, press F9 to reset and wait. for some reason this causes you to gain control of Jill after the text screens have finished.
The first 2 demo scene's are pretty useless as they are both fairly early into the run and there will be a strange bug that causes any healing to put you in the danger condition.
The 3rd demo scene however has you start outside of the train with the dogs allowing you to grab the wrench at the start of the game and not have to backtrack later on. After a bit of testing i found that it is possible to complete the game from this state and the healing bug present in the first 2 scenes is not present here.
As of yet i have not found a way to replicate this without SRT and although SRT is currently allowed in runs, i have a feeling this is a step to far (lol) I believe sub 40 may be possible but i am not skilled enough to test it properly myself
Ive been sitting on this for a while now as there was a debate about SRT that had recently happened and i didnt want to restart that so soon.
@Julian No, you do not need the SRT to do this trick because you do not need to press F9.
For TWN PC: Go to Original Mode, select Light Mode then press cancel key twice (Goes back to main menu). Load a save file that was in Heavy Mode and it will now be in Light Mode.
Hmmm... Why there is no such category using this glitch? I think it would be interesting for other players, but I am not sure. If you use demo glitch than you should run the game in a different way (at least the first third of the game).
It's a different route yes, and it's completable, but is not a lot faster than the normal one. A lot of backtracking has to be done, so the timesave in city is like 1-2 minutes.
