Well...I found that it seemed to get stuck on a picture after awhile, and wouldn't let me switch to another one. Also, it'd probably be nice to be able to have a browser so you can choose which image you wanna see..dunno how hard that'd be to do though. And do you think it's possible to increase the sensitivity? I found it to be incredibly finnicky...though I guess it's quite understandable, seeing as how the DS was never meant to use multitouch in the first place.

It is rather finnicky, yes, but I'm thinking that perhaps all it needs is some calibration. The Colors! application indicates that different DS systems have different pressure sensitivities, and looking through the sourcecode to this multitouch program, it looks like there are a few "magic numbers" scattered about for threshold values and such. Perhaps if these magic numbers could be changed by the user, better results could be had.
It looks like he's using a PAlib-provided function to load the bitmap into memory and display it at a specific zoom level, and this function appears to only work with images with a maximum resolution of 256x192. I wonder if there's an easy way to increase the max resolution without rewriting the whole thing...
I too sometimes get the issue where it gets stuck on a specific picture, and I don't know why this is. Some bug in the file-reading code I suspect.
hmm no it is because this app is limited to loading 4 files yet. so if you choose the 5th one or 6th it stays on the 4th but "the file number = 6" so you have to go back to 5 and then to 4 and then to 3 to get another image, so yes you could see it as a bugDanTheManMS said:
and yes there are some magic numbers
Would be nice to have a zoom function which can load bigger files...
Hello. I am searching your program sources but it seem they are offline.
Could someone upload again ??
A lot of thanks

A lot of thanks
You've resurrected a thread from 5 years back, that might be the problem. All GBATemp downloads have moved on to FileTrip, use that for future reference.

Hi,excuse me for posting here , i found the creator had posted and i did thinking he could see .
Thanks for your answer , i would like ask something : i have download the post but it has only the binary ,no the sources (which was offline).
i have searched on filetrip but i dont see them
sorry and again excuse me
thanks
I found no other files matching what you're looking for - you'll have to try and contact the original creator or use your Google-fu to find the source. It's not like it would be of much use to you though - the application was based on PALib which is grossly outdated at this point.
A lot of thanks for all. I will try contact the author (on google only give me a link which is offline)
I know it use PALIB but i am interested only in the multitouch part he implemented (as i read it is diferent as Mtouch lib) and i would love try to update it and try to add dsi and 3ds screen support (i am doing some experiment with this screen and my arduino)
thanks for all

I do warn you that all implementations of multitouch on the DS's screen are... uhm... "hit and miss" at best - it's simply a resistive screen and those aren't great at multitouch unless specifically designed to support it. It's actually easier to implement pressure sensitivity, but the results vary between the screens, making is application troublesome. Good luck in your search!
A lot of thanks for all.i know i never will have "real multitouch" (and i doesnt search also) and the problem which same code doesnt work well (or simply doesnt work ) on other touchscreens .
The objetive is go on learning about digital-analog electronic/programing devices with experiments/trials .
Now i am "studing" touchscreens : my intention is create some kind of "macro" or "library" could use hands for simple gestures : pinch ,zoom and roll (and maybe other) on resitive screen.
I have already several ideas for implement them ( the touchscreen "see" this as huge finger) for ths i wanted see what has been done already.
(i have remember now i found a great article on arduino forums about how filter resistive touchscreen data for better adquracy ,if you wanna i can send the link)
Also is curious the fact than on capacitive touchscreen are searching the oposite : a way to use a pen/stylus
with the precision of resistive touchscreen ( i read recently nvidea tegra k1 make some kind stuff via hardware
for its "pen" ; and samsung (watcom really) is making a lot of invest for its SPEN technology.
I make mention of this because i also have some snips (which i have to develop more) using a touchpad
(or other capacitive ) for "emulating" the precision of resistive touchscreen.
As example i have on mind is using the touchpad for android x86 for gestures , create a simple pen (only need
doest break the touchpad and give them some contact with my hand ) for more precission matters and
use as actually does (emulating a mouse)
Again thanks for all
yours

You can make a post on the DS forum about your findings, and they'll do their best to respond. They have a GBAtemp account here, you know. -

Well, from what I've heard from my parents, he had a seizure last night, perhaps an epileptic episode, fucking died, had a near death experience, my dad called the paramedics, they showed up, took him to the hospital, and he woke up covered in tubes, and started complaining.
