Okay, that's odd. You're right of course. But there shouldn't be?
I have no idea where it got those savegame files from. Must've made them during the creation of the TAS.
But the curious this is the "desync". It's caused by the game bein in the wrong video settings.
While you're playing, when you open the menu (the big P in the middle of the inventory), you can choose between "Half Screen" and "Full Screen".
By default for me it was set to "Half Screen", but apparently it was "Full Screen" on your end. The final chase scene happens all in that specified video format, meaning for me the window was a lot smaller than for you, and therefore my inputs are in the right position for "Half Screen" but the wrong position for "Full Screen".
Can you please confirm somehow that the default on your end was indeed "Full Screen"?
Now there's 2 ways of fixing that. The easy slow fix that costs frames is to add like 10 menu frames where that setting is changed at the very beginning.
The proper way would be for me to rerecord the final chase in full screen. I personally highly favour that second option.
If it weren't for

BUG
https://github.com/clementgallet/libTAS/issues/540
That prevents me from TASing Sierra games in Full screen. If it weren't for this bug I'd have already started more TASes.
In fact, I only discovered this bug AFTER finishing this Phantas 1 Tas, because it was "Half Screen" by default on my end and didn't happen.
Open for debate and discussion. I mean we can always do the slow fix, and then if someone scoops me for those 10 frames I won't be mad.
