Title: Tutorial: create moving screenshots of a TI-nspire
Post by: Jonius7 on September 04, 2010, 08:19:33 pm
Tutorial: Create Moving Screenshots of a TI-nspire
1.   Open nspire_emu
2.   Open CalcCapture
3.   Click the configuration button in the top right hand corner
4.   Click New
5.   Name it nspire_emu or something that resembles TI-nspire for you.
6.   Click the little button to the right of the Window title box
7.   A dialogue box will pop up.
8.   Find nspire_emu and select it.
9.   Now make sure you can see both the CalcCapture window and the nspire_emu window on your screen.
10.   Click the capture button on the left and set the pixel options so that it captures the emulator screen
11.   Recommended settings that worked for me are: Screen Width: 320, Screen Height 240, Screen Top 43, Screen Left, 83. Settings may vary from computer to computer.
12.   Make sure that you save your config settings at the top right by clicking Ok when it indicates config has changed.
a.   If it does not appear you may have not selected the emulator correctly from the drop down menu. Retract to step 4 and try again.
13.   Close the window and go back to the first window
14.   Click on the configuration tab
15.   Press the new button to create a new configuration for capturing images
16.   Now there are two types of configuration I recommend making:
a.   Name the first configuration nspire_gray or something similar, set the palette to Grayscale (256 shades) and set Contrast, Lightness, Darkness, Noise to 0
b.   Name the second configuration nspire_color or something similar, set the palette to Optimised (256 colors) and set Contrast, Lightness, Darkness, Noise to 0
c.   Don’t forget to save the config when it indicates config has changed.
d.   Advantages and disadvanges of the configurations are outlined next step.
17.   In file properties change the capture type to animation. It is recommended that the capture interval and GIF interval are set to as low as possible, however I have created decent screenshots with higher intervals for both.
a.   Grayscale config slows down the overall fps when capturing, and can be useful if it doesn’t really matter if there are slight lapses in fps from time to time and to slow things down in general. However I have discovered the file size is significantly larger than when using 256 colors
b.   Color config provides a nice flowing image, fps is much quicker (for some reason) and the file size is significantly smaller than when using Grayscale. However, the frame rate is slightly faster than in real time.
18.   Choose the filename directory for your screenshot
19.   You can start capturing by clicking the capture button or you can set a hotkey to start capturing when it is pressed. Choices are printscreen and numlock.
20.   Record on the emulator
21.   Click stop capturing.
22.   You now have a nice moving screenshot.

There is some emulator out there somewhere but I don't know where to get it or how it works.

It's Goplat's emulator at http://www.unitedti.org/forum/index.php?showtopic=8191&view=findpost&p=138702 (http://www.unitedti.org/forum/index.php?showtopic=8191&view=findpost&p=138702).

Post by: DJ Omnimaga on September 04, 2010, 08:26:05 pm
Indeed. It doesn't create smooth screenshots, though :(

The only way to have high framerate is to slow down the Nspire emu a lot, capture at the default speed then use a video program (VirtualDub, for example) that supports GIF and edit the screenshot in there. But then you get an AVI file. Alternatively you can set the final screenshot to be faster than the speed at which it was captured, so it can make it smooth without using a video. Keep in mind Nspire screenshots are really massive, though. About 30 seconds of capture is 5 MB, I think.

yeah i have that but how to link it with calccapture
wiat i  think ive got it

ive got it with xspire's 026 gtk emulator!!! it's a bit complicated though.

here's a tutorial for anyone who needs it
if you have the emanulator set up
1. open calccapture
2. go to configuration at the top right hand corner
3. click new
4. name it nspire_emu or something
5. make sure the emulator is already running and click window title
6. find nspire_emu and select it
7, on the left click capture and set the pixel options so that it has the screen
8. close the window and go back to the first window
9. click on the configuration tab
10. choose animation on capture type
11. choose filename
12. click on capture
13. do your stuff on the emaulator
14. click stop catpuring
15. done!
16. its not that good quality.

Hmm seems pretty fine to me. However, the Gtk emu seems to screw up the display a bit

i know it's good, however i do know that xpire's emu does make the display unclear, ive looked on unitedti.org and there havent been any updates.
i don't really know how to use the goplat commandline version

Yeah same, I had to ask Bwang or someone else for a version that he setup so we just double-click a batch file to run it. I'm no good with command line.

ok i just updated my emulator. i think i was actually making a mistake when i was referring to xspires and goplats, i updated my 026 gtk to 026r1, i copied my whole folder then i got the goplat 031 and copied that stuff into the folders that i already had. i ran the specially made batch file i had (im not sure its xspires but i think it is) and did options and it came up with goplat's 031!!! so now i have 2 copies, when i want the graphical version i posted in my screenshot above i go back to my original folder, when i want to run os2.1 then i go to the goplat version. i wish however that xspire would post more updates for a clearer screen and update his gtk version to 031.

I shall be posting my 'HYBRID' 031 version soon onto here.

NOTE: now it is here! i had to remove the raw, img, and os files otherwise the file would be humoungous to download (was 189MB now just under 4MB

also i shall be adding this to my list of tutorials i have to complete at my website: http://www.jhgenius01.webs.com

one problem... i can't send a document in goplat's 031 version but i can in the gtk version
maybe because i modified it too much, ill try and fix it

ok made a mistake, its because installed os1.1 onto gtk version and i could send document. however i also tried installing 2.0 onto gtk version when i press connect i notice in the cmd that it says Unknown OS version, hmmm... this also is displayed when i try to install 2.0 and 2.1 onto goplat's version. any help here?

ok i think i got it now, i read the 026 readme and foundout that only 1.7 can transfer the documents

I don't know if you are still having trouble running the emulator (w/ the command line format), but here is a batch file that will run it for you (attached).

Just make sure your .rom file is named nspire.rom and your boot2 is named boot2.img.raw and it is in the same folder as these two files, along with Goplat's latestest version or ncubate (which I would recommend), which should be named "emulator.exe" for usage with this batch file.

Likewise, if you don't want to rename all of these files, just open up the batch file with notepad, and change the names of these respective files to whatever you want them to be!  This can be helpful if you want to run more than one .rom version.

Also, I believe this is a trick that will allow you to send files to OS 2.0 (it takes a little bit of time though):

Make a new 1.7 .rom image
Send the file
Upgrade your OS (Connect, Upgrade OS) to 2.0
Run the file!

This might take a while, espically updating the OS, but if you increase the speed of the emulator, it might make it go faster if you really need to use a file on the newer OS.

I think ncubate is by ExtendeD, not Goplat, actually.

I first found that trick when I wanted to try out Nleash on the emulator.  It works perfectly!

I wish you luck with all of your projects (and screenshots :)), jhgenius01!

I tried your poker game for a short period of time today, and it seems pretty nice, espically since it is in Nspire BASIC.

Great job! :)

Phew! I have exams and i just sat a physics exam, as i will be busy over the next few days, I won't have time to develop my games. I hope to order a ti-84 keypad and USB link today EDIT (8Sep2010): i didnt get it after all but got a faulty unit-to-unit cable replacedand I hope that it will arrive in the next few days otherwise I won't be there to receive the package!!! Next Tuesday I won't be in australia, so just before I leave I will post an exclusive beta release of my upcoming strategy for the nspire, Battle of 16s.

After that I won't be available for at least 17 days.

thank you apcalc, i am still not finished with the hold' em project. i released  a new version, 0.9.1 yesterday, and i hope to make the game much more graphical, like elliot way's hearts, and solitaire, however i will need to learn more advanced programming which i don't know how to yet. I followed the programming tutorials part 1 on ticalc.org but i would like to know how to create graphical games, also i would like to create computer AIs, but that would be complicated, i would appreciate it if someone would help i would put your name in the contributors

ok ive tried it
nice but i still like the FULL version that i hybrid crossed with goplat's because it actually makes the rom file for you through easy steps and also the boot2.img.raw file too. also the version i have allows you to name the files to anything you want. try it!!! it's back on the previous page.

I believe I have a copy of that, but I still find the cmd interface easier because I find myself constantly opening and closing the emulator when I am testing my C programs.  I am too impatient to have to go through the menus every time I start the emulator.  I do find that I use that to make a new .rom file, though, as I don't have to do that too often. ;)

i should say that the gtk with the nice batch file and gui is credited to these authors
original emu - goplat
skin for the emu - xspire
batch file - Levak
Edited readme and batch file soon to be released - jhgenius01

Aah ok.

Just one thing, though, it is recommended to avoid double-posting with extremly short amount of time between posts. Your last two posts are fine, but the http://ourl.ca/6943/115099 one might have been a bit too early

I still have not done this again! I'll see what I can do.
Also I didn't realise I sounded so noobish back then.
Title: Re: Tutorial: create moving screenshots of a TI-nspire
Post by: Jonius7 on February 25, 2012, 08:54:50 pm
I have discovered that setting Calccapture to Greyscale (256 Colors) dramatically increases the file size and also slows down frame rate. In some games this may be ok, but for others, the fps stuttering will be unbearable. Eg: on Cubefield it was bearable, on Gravity Guy it just didn't work.
However sometimes color produces a faster fps rate than it should.


BIGEDIT!!!:
Just added stuff and detail to my moving screenshot I created over a year ago. See first post. Should put this up in the tutorials section.
