Not necessarily, the main CPU of the DS is just an ARM946E-S, which is a 32-bit CPU, and it runs at 67MHz. The secondary processor is an ARM7TDMI, which is the same CPU that the GBA uses (hence the backwards compatibility). It runs in both 32 and 16 bit modes, and has a clock speed of 33MHz. Most computers being sold today use dual core 64 bit CPUs running at over 2GHz, and many computers currently used in homes use a 32 bit CPU running at over 1GHz. At that speed, it wouldn't really be a problem to emulate both of the DS's CPUs so long as you weren't multitasking. It also doesn't have that much memory, at only 4MB. Most typical computers these days have at least 256 MB of memory, not to mention HDD based virtual memory (and many argue that for Windows, all that and more is necessary ). The real trick in making the emulator run is to emulate the CPUs correctly, which can take time to figure out, and to properly run the firmware. After that it's just a matter of tweaking the bugs out.

Also, there IS a FFIIIDS ROM available on the internet. A friend of mine has it, but as said before it won't run on any current DS emulators.
