Did you use the Screen Receiver to generate those?

How? O.O

The last time I tried taking screenshots from the screen receiver, it only let me capture while the calc was not busy or was in pause mode. When a while loop ran, for example, it wouldn't capture. :(

Also the emulator won't let us send files. X.x

When using the GetKey() function, it allows that interrupt through, and that's the function I use for keys.

Merth, it's not the Getkey() function. The USB connection triggers interrupts that I believe occur whenever the cable is plugged it as long as the interrupt table is intact.

Weird, so I assume in ASM/C it's possible, but not in BASIC?

It only works in GetKey(), so there's something in there. The non-blocking calls don't handle MENU or Screen Receiver. Also, I accidentally down voted your post when I was trying to hit quote. So then I upvoted it.

Hmm.. I wonder... does this mean that in a BASIC program, if I had a getkey command running in every loop, it would capture? I will have to try this when I have time.

Do you mean like:

Code: [Select]
While (TRUE)
If GetKey
...
End

Would it capture that?

I don't think that would be captureable... The Casio-BASIC GetKey is non-blocking, if I recall correctly.

The screen receiver seems to work in BASIC progs only when there is little action. For example when the calc is is a repeat getkey loop then it will send an image, but if there are many drawing operations going on then the screen receiver will wait till the drawing calms down. I'm not sure if it will work when there are math only operations going on.

List of stuff I need to do before September:
1. Finish the Emulator of the Casio Prizm (in active development)
2. Finish the the SH3 asm IDE/assembler/linker program (in active development)
3. Create a partial Java virtual machine  for the Prizm (not started)
4. Create Axe for the Prizm with an Axe legacy mode (in planning phase)
5. Develop a large set of C and asm libraries for the Prizm (some progress)
6. Create an emulator of the 83+ for the Prizm (not started)
7. Create a well polished game that showcases the ability of the Casio Prizm (not started)

Hmm I see now. I assume if there are many draw functions you need to spam like 10 getkey commands in your loop code, right?

Actually I recently found out a little more about how the screen receiver works. It appears to use the dmac to do quick transfers of the vram to the usb. The problem is that the vram to DD (screen draw) also uses the dmac so screen reciever must wait till it is free. What I've seen is if you do a for loop to 100,000 with no drawing with screen receiver running there is little slowdown to your code, but if it is graphic intensive there still is little slowdown, but screen receiver won't do an transfers. Also if screen receiver is already using the dmac then directdraw must wait till it is done. The full dmac transfer takes about 1/22 of a second, but you can have your own code running during this time.

Hmm strange. I think we definitively need a good third-party emulator for screenshots, because currently it's annoying to capture anything X.x
