The biggest problem with the PSP version's borked physics is if you have any experience with the original title, as there are some ways of navigating boards that are just no longer possible with the wonky line action. This is, of course, a lot more important if you're one of those weirdos that can slingshot themselves from one end of the field to the other in 30 seconds or less. Line physics are a bit hard to illustrate in a video, but I like this particular bug:

What version of DS do you have? I've got a DS Lite, and I have to admit that the diagonals are a little soggy on the control pad. I've pretty much learned just to mash extra hard in the diagonal direction for the game (oddly, this is the only title I own where I've really needed diagonals to be responsive; it's a surprise I've never ran into this problem with other games), but I like to imagine that on any iteration of the DSi or even the good old chunky first-gen DS, the d-pad is much better thanks to its size and use of microswitches.
And just to note, if you try and have a go at this one through emulation or other means, the game will crap out on you in a fairly creative way after about 10 minutes as an antipiracy measure. Basically, your lure just stops sticking to anything, even in the little animated sequences that introduce new techniques for the levels.
