or CT, were you being humorous about how we naturally use both thumbs on a gamepad, therefore using 2 stylii isn't so different.
are you people having protection foils on your NDS touch screen? i saw some public installed nintendo ds in a local warehouse beeing BADLY worn and scratched on the surface.... i have a P800 sony ericsson handy and iam happy i have such protection foils on its touchscreen. it happens way to often that it slips off my hands / desk and falls onto the touch. without the foil it would have some serious scratches.
I think we've found our Tetris Attack Japan Finals video. But then the skill chain (sliding a tile into the space left by a removed tile) appears easier with a stylus because instead of rejecting a press of the A Button unless the tiles have completely disappeared, it appears to have "busy number redial": it retries the swap each frame until the space opens up. The gravity rate appears to be much slower than the 1G of TA on Super NES as well.
Looks like he's playing on easy (could be normal) but the gravity on hard is almost instant in PdPDS. edit: Is that a reference to how people call that TAP vid "Tetris Japan Finals" all the time? Because the videos I linked to are really just a demonstration of the combo system in the game.
On TA for Super NES, easy/medium/hard affected only the delay between the last block in a combo disappearing (which turns the cleared blocks from invisible blocks to air) and the onset of gravity above that combo, not the rate (which was 1G on easy, medium, and hard).
Super Mario 64 DS has a minigame that uses the touch-screen to fire rocks at bob-ombs. After a long high-score competition on that game, the extensive playing meant the centre of the touch-screen was completely wrecked with scratches. Just from using the stylus a lot in the same region of the screen. Luckily, Nintendo UK replaced his DS for free, as it was still under warranty. I use screen protectors. They scratch relatively easy, but at least it's cheaper to replace than the screen. I'm on my 3rd set probably now.
tepples: In addition to hover time, the different difficulties in the SNES version affect how long the panels flash after matching and how long it takes for each "pop" animation. 2 styluses/2 thumbs: Yeah I was sort of being humourous. Technically you could play the game using only one thumb... Anyhow, if you want to see some awesome double stylus action look up Trauma Centre videos. Not every video will use 2, but those that do are really impressive. scratched screens: I absolutely have had no problems, and I've played a lot of Meteos, Polarium, Magnetica, Puzzle Quest, and, erm, Pokemon Trozei. All those games use sliding motions of the stylus. Maybe I have a light touch? I write for real with a lot of force though. (I use a DS Lite btw)
Yeah, I've seen those Trauma Center vids, and as I mentioned before I used two stylii in the whac-a-mole minigame (where you just tap the moles) in Mario. I'm just not convinced of the advantages in this particular game. You have to be quick on the block feed button if you want to do big combos, and while you could hold your second stylus there for most of the time, you could just aswell just feed the blocks with the shoulder buttons instead - and play with a single stylus. Edit: I don't have any troubles with scratched screens either, and I have also played many stylus based games.
