Grunz will hate me for that. But just fyi:
After seeing this video
http://www.youtube.com/watch?v=jCVZe2fqc_c I tested a little and I'm pretty sure that J 1.1 has the same bomb physics as the U-version.
That means it has the fast text, the good bomb physics and a shortcut in PF (the room where you shoot the vesp nest from has a direct connection to the hookshot room).
The only thing that is missing is the zora shield while holding still in water.
And the GC J-version is a direct backport of the U-version, meaning it has all the improvements of U, plus faster text. Ofcourse that also means the shortcut in PF is removed.
But the sad thing is: Japanese runs can easily beat Grunzs TAS. Since all Jianos testing was done on J 1.0 we thought J was useless, originally...
I know it's not rally a problem for tasvideos, but it's still sad.
And to make matters worse I think 1.1 and GC have less lag.
Since U came out 6 months after J it makes sense that J 1.1 and U 1.0 are closely related. Why didn't anyone test that before? o.O
Edit: after further testing I'm not sure how the bomb physics behave in 1.1. They don't seem to be quite as crappy as n 1.0, but they also don't seem up to par with U, as you have to swing your sword before you can chu hover against a wall.
GC version however stil seems to be a port of U.
Woud be cool if you could look into it a little, Grunz.
Edit2: Ah I think from the comments I now understand why you have to swing your sword first. It has nothing to do with bomb physics. It's just that the power crouch stab works in J. Which means if you crouch stab without doing anything with your sword beforehand ISG will have the power of 0. And the power of 0 won't explode the chu.
So you have to swing your sword once to get it to the power of 1.
Btw. working crouch stab would also be a plus point for J...
Still would like to know how the bomb physics hold up compared to the U version, i.e. if HISSing and triple staircases are possible, if hovers reach the same height, etc. And if 1.1-J and GC-J are different in that respect.
If hissing and triple staircases are possible J seems way superior
