I was speculating about the Nspire, having found out that it uses an ARM chip. Since that is the case, comparison to other ARM devices should be fairly close, correct?

The point is, if they are truly in perspective to each other, the DS is significantly less powerful than the nspire. For instance:

Nspire has 150 MHz processor (according to ticalc.org) DS has two: 66Mhz and 33Mhz.
Nspire has 16MB of ram (not flash), DS has 4MB.

This means that almost anything that can run on DS (not touchscreen dependent) could run on the Nspire! For example: SnemulDS (SNES), A billion different NES emulators, and various other homebrew.

Also, since they are both ARM, could a call style setup like the one in TI-Boy for the 84 be used for GBA? I feel much more uncertain about this one, but it may be a possibility so I'll throw it out there.

Thanks in advance!

Doesn't the DS have some sort of video card or chip to process graphics, though? We must not just take the processor and memory into account, but the entire hardware as well.

That said, the GBC emulator runs 6x faster than normal if you turn off speed throttling, and calc84 was still new to ARM assembly when he wrote it, meaning who knows if he won't discover any better optimizations.

Calc84 also did some 3D stuff. The polygons were not sorted but they supported 16 grays with dithering (meaning about 32 shades) and still had about 70 fps.

From what I've read from googling, the second CPU is sometimes used for Graphics, and I can find no technical specifications that say there is an actual GPU, but there might be one built into the processor.

Good to know about that 3d thing! Personally, SNES emulation has me the most excited, and has almost no 3d capabilities whatsoever (discounting Super FX and the like, since they are apparently VERY hard to emulate)  and simply has sprites with multiple backgrounds to make up separate layers.

I just had a very curious idea: DevkitPro on the Nspire. Probably a stupid idea, but it could be interesting.

Stupid mosquitoes! They just came back in my area.

Keep in mind that the DS does have built-in 2d rendering hardware though, which is probably used in its SNES emulators.

Sound emulation could be very possible, but for SNES it may be hard to reproduce the sound exactly. Plus we have yet to discover how to output sound through the link port anyway (84+ keypad). In Star Ocean the main issue was graphics compression used I think. It's what caused the most issues when emulating it.

I think other games might be fine, plus they would fit well in the calc resolution, except maybe Secret Of Mana, which used a much higher resolution width (512 pixels) and would most likely need to be scaled down:

I didn't have slow down problems in SoM/SD2, even on my Pentium II 350 MHz. I used Zsnes, though. Snes9x ran choppily on my old PC.

As for Ndless for mac, Idk if it would be easy, you would probably need to ask an expert Mac programmer. I think on United-TI forum there was talk about porting Ndless to Mac and Linux, but since Ndless 2.0 will most likely obsolete Ndless 1.0 soon, they might prefer to wait until it's out.

Wow, these are cool ideas!

I like the usb sound card one.  Could that work?

Mhmm that's great! I should mayeb get one at one point. Is it easily findable in offline stores, though? Because you have to remember about 95% of the users on this forum are under 18 and their parents won't let them buy things online or they can't buy online at all.
