Some of the legitimate ones, yes!

They're all legit.

Just post your times if thine claims be true or else I say yer a...poser!

Hahahahahahaha I know all along about the glitches, I have managed the frappe one ( and I think royal raceway, which is my favorite course, too)! I don't like that way, I prefer  a  real skills (the shade) face off :P. Of course it needs a lot of skill to manage some of the glitches ( I mention the royal raceway one, because I discovered it when I was playing a gran prix against my brother and he hit me in the right place and right time (aftewards I was cunnigly pursuing that, braking on purpose without an apparent reason e.t.c) .                                                                                       

I just saw the note, nice! I'll post mine someday, I hope my brother hasn't erased my time records (as he was used to be doing)... Mario Raceway is my obsession, I had nearly destroyed on of my controller's stick.

Wow! It's just the opposite way around for me: I still have tons of trouble with the ramp shortcut in Royal Raceway to this day. That's like the toughest one in the game that you can find in the guide to me! The fact that the ramp also boosts your speed throws off my angling. I find it much easier to make the first wall jump in Wario Stadium, for example, precisely because there aren't any factors like that involved. I can pull off at least that first wall jump in Wario Stadium like 4 out of every 5 times. Jumping through the wall on D.K.'s Jungle Parkway is actually pretty tough for me too, but I can pull that one off more often since I know basically where to jump and basically how; I just find it tough to actually execute at top speed (which I've discovered is, in fact, necessary) given the precise angling required. Still, 1 out of every 25 or 30 times I can pull it off on all three laps and that's all you need to set Time Trial records.

I will agree with you though that fundamentally making the long jump in Rainbow Road is actually among the easier big shortcuts in the game. Once you know the tile you need to jump from, it's a piece of cake. It just looks fancy...which makes it even more fun to do.

Oh, the Frappe Snowland trick is super easy actually! Just turn around from the starting line and drive onto the wooden bridge, then turn around again. From there, just hop directly from the bridge onto the right-hand snow bank and drive out on the snow until Lakitu picks you up, being sure to pass the starting line before he does (i.e. don't drive out at too far of an angle). From there, he puts you down back on the wooden bridge. Just repeat that last step two more times; back up and hop directly onto the snow bank and drive out past the starting line until Lakitu picks you up. Each subsequent time, you skip a lap. Then on the final lap, just drive through the starting line. In Time Trial mode, I recommend using your mushrooms after you land on the snow bank to speed up the drive into Lakitu's waiting fishing lure. Just make sure that you hop DIRECTLY from the bridge to the snow bank on the right each time because if your wheels touch the driveway in-between, the trick won't work. After a few tries, you'll likely have mastered it and be able to consistently finish the race in under 50 seconds, if not under 40, including in Grand Prix mode.

The only times I've managed to like skip whole parts of Bowser's Castle in Mario Kart 64 was when I got hit with a shell that knocked me clear to a different part of the course...which of course ain't possible in Time Trial mode and were freak accidents anyway. Maybe you discovered a glitch that I didn't!

Mario Raceway is fun! I was motivated to master that track by a Nintendo Power contest where you could win a gold N64 controller if your record time ranked in well enough. I never did master the big shortcut where you jump through the right-hand side of the wall to skip half the course, but I have been able to pull off the smaller one where you jump the left-hand sided of the wall to skip the hairpin turn on all three laps a number of times and that's helped my record, but my fastest time to this date remains more then 20 seconds behind the one set by the programmers and play testers ahead of the game's release according to my '97 player's guide. And people have since bested even that record. Jeez! Well it was reportedly the developers' favorite track and I think I get why. I like Koopa Troopa Beach, Wario Stadium, and D.K.'s Jungle Parkway best myself, I think. (Although I am concerned about that boat's passengers, seeing as they seem to be headed straight for the waterfall! ) Well and Toad's Turnpike in Mirror Mode with the oncoming traffic 'cause that just makes for crazy races, lol! Also really, really like the background songs in Toad's Turnpike and Rainbow Road in particular.

Heh, well, "occasionally" means a lot less than once in 25-30 times for me, even for only one lap.

For Bowser's Castle I was thinking about how you could drive on top of the walls and skip all kinds of things near the end, but looking up a video of this, it looks a whole lot less spectacular than I remembered lol.

Lol, I understand! The D.K. Jungle Parkway shortcut where you jump through the wall takes a LOT of practice and even though is more than a little difficult. I've memorized the spot -- the particular sun-soaked little space on the ground -- where you need to jump from over the years, as well as the angle that you have to jump from, and that's helped a lot, but it's still 50 times easier said than done, considering you have to be barreling toward the corner at full speed and a curvature! The window for proper execution is exceedingly small.

Ooooohhh yeah, I remember that Bowser's Castle shortcut! But I don't remember ever being able to do it in the original Mario Kart 64 version of the course. Were you playing the N64 version or like Mario Kart Wii's version like in the video?

Then why doesn't he say so?

(Also, thanks!)

The N64 version, also played the Wii version of course but I didn’t dabble in time trail anymore at that point. I don’t remember whether or not I thought it was hard though.
