Good to see the worldwide reach of this site add another nation to the list.
To anyone who's turned off by the 73.3MB filesize of blaze's link, I downloaded it to see what it was. It's an assortment of clips of SA2 levels, showing off trick points. You probably already know of most of them for Sonic and Shadow. Tails' and Eggman's sections show how you can get a bunch of x10 and x11 lock-ons, as well as the obvious but useless x32 in Weapons Bed. It finishes off with the Death Chamber 3 floor clip (albeit with a bad point of re-entry to the stage), the double-perfect in Dry Lagoon 5, and the good old Meteor Herd 5 divebomb to close out that level in 0:44.95 which would be good for 5th place. Altogether, rather well put together, except for the low quality audio used in Tails' section (taken from his SA1 theme instead of SA2 for some reason).
[EDIT] I didn't see it at first, since I have signatures turned off, but the 0060 link in blaze's signature is Cannon's Core 1 in 1:32.02 (the 640x480 resolution combined with the 7:09 file length makes it unlikely to be added to the videos page for now). A lot of it is already known to top players here, but there's some exceptional placement management in Eggman's first moving block room, and it turns out Knuckles can jam through the ceiling without having to use a moving block (more like Death Chamber that way), meaning the timestop switch in that room can be taken advantage of. I used that new method to cut 9 seconds off my Cannon's Core 5 time [EDIT2] and 15 seconds off m1, as well as 16 off m3.
