Tutorial: Create Moving Screenshots of a TI-nspire
Screenshots and better instructions coming soon!


This can also apply to other emulators, such as WabbitEmu, config just has to be changed.
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.
