I've found that
"Save anywhere trick" on GameFAQs is also available with the pause menu abuse. For those who doesn't know what Save anywhere trick is, it is a trick to allow you to save the game literally anywhere. And the effect never disappears unless you enter a room with a savepoint. In Chrono Trigger, an event check point has usually only 16 pixels wide. That means you can skip some unavoidable cutscenes and battles if you manage to go beyond a check point and save the game before you lose control.
Here are all the result I got:
Yakra skip
Heckran skip
Zombor skip v2 & Tata skip
Also,
here is a performance showing how to make it available Save anywhere trick at the End of Time. It would be about 500 frames slower than usual, but it's necessary to perform the trick at Zenan Bridge and Denadoro Mountains as above.
I think you may need further explanation about Tata skip. Actually, there are a few points where two different landforms share the same coordinates in the game. And apparently the game saves only what coordinates are, not which landform Crono is. So, if you save/load the game on such a point, Crono will be located at one predeterminded landform regardless of which landform he was at. Very fortunately, it is always upper landform that Crono is located in such cases at Denadoro Mountains.
Anyway, I hope you enjoy it.
Also, Here is a detailed explanation about Lavos Shell skip trick. First of all, here are two facts that makes it possible to skip Lavos Shell:
1) In trying to warp to A.D.1999, if you somehow open the menu just before the fade-out starts, then the coordinates that Crono will appear at in 1999 are totally the same with where he was at the End of Time.
2) If that x-coordinate is the same with the Lavos' hole x-coordinate (which is 8) and that y-coordinate is the same with or below the Lavos' hole y-coordinate (which is 8), then the game immediately sends him into Lavos Shell.
The thing is, you can directly access the inside of Shell Lavos if you manage to open the menu at (8,8 or any less) at the End of Time right before the fade-out starts. Of course it is out of the question in a normal manner. First, you lose control of your character as soon as you examine the backet. Second, (8,8 or any less) is outside the moveable area. To solve the problem, I took the help of another two gates, Bangor Dome gate and Tyran Fortless gate.
Bangor Dome gate was used to change the direction that Crono flies to, and to get close to the needed position. Also, because Bangor Dome gate is the most left below gate out of nine gates, unlike the other gates, a line segment between the backet and the position Crono flies to contains the upper right corner of the gate floor, a moveable area, of course. This is of great importance after you regain control.
Tyran Fortless gate was used to regain control and occur the second flying action. If you choose "yes" just before Crono starts flying, you can open the menu again. And if you change your party's order twice in that condition, Crono gets out of flying and you can control Crono again. As I said above, the line Crono fly along contains the moveable area. So if you restore the control on that area, you can have Crono run around as usual.
If the other two characters finishes flying, Crono takes the second flying action. Very fortunately, a line segment between the bottom left corner and the position Crono flies to contains (8,8or7). And the fade-out starts when Crono passes on (8,8or7). So I simply moved Crono to the bottom left before he started flying again and opened the menu on a certain timing. Crono appeared at the same coordinates with Lavos' hole and Lavos Shell skip was possible.
Also, I think the other gates proably wouldn't play the Tyran Fortless gate's role well since all the gate message is generally shown in order of priority no matter how you examine them. And it is only the Tyran Fortless message that is always shown after the Bangor Dome message.
I myself have not exactly grasped the detail yet. So the explanation may be redundant and arbitrary.. But I hope the explanation will clear up some confusion.
To Vykan12: I uploaded my test tas avi on Megaupload.

I was not sure Megaupload was the right place and image quality isn't good at all. But if you have troble watching the smv again, you may want to try to downroad it from there.
To Saturn: Thank you Saturn.:) But I honestly think sub 2 hours will be still far from realistic, even with Lavos shell skip trick and all the above new skip trick. My current target times is to break 2:15. I'm doing everything I can in order to accomplish that goal.
