About the runs : Trevor Seguin made a segmented run with Jill, you can find that on
http://www.youtube.com/watch?v=R3qXLfcvV1Y (1st part out of 10).
I'm mostly referring to this run because it's pretty damn good, and it's with Jill :).
So, for the run I'm ok. About the dogs, I managed to kill only the important one, but without rapid firing... I guess it can be several seconds faster, but I can't get why the glitch isn't working (and I tried A LOT).
If someone wants to help out, this is the most important part. Why isn't rapid firing working on emulator everytime...
Furthermore, on console, I almost managed to get the same skip as the PS1 TAS, what I like to call the Chemical skip. Some invisible wall stopped me though, and teleported Jill everytime I got close to the mask. How I did was : turn around, and get hit (Jill makes a few steps backwards when getting hit). At some point you'll get teleported, and I don't really know if there's the same problem on PS1, though. I'll have to investigate when I'll get there. For now, DOGS ! T_T
