Hacking Most Stable NDS Emulator?

[Tom Bombadildo]

i don't understand. is the DS much more powerful than the PS1? the PS1 seems way more powerful and the PSP can run it

The reason the PSP can play PS1 games is because it uses the same MIPS architecture. Creating an emulator for it was simple, and Sony did it themselves.

The DS, on the otherhand, uses a different architecture and is being coded by homebrew devs who may or may not know all the ins or outs of the Vita's hardware. You also have to remember the Vita was only hacked 4 months ago or so, creating a full speed emulator for anything as complex as that is going to take a lot of time.

The psp runs the psone games because the system was designed by Sony to be able to do that and it was with some manipulation that we are able to feed Sony's psone player an eboot file to run, there wasn't really a psone emulator made from the ground up on the psp.

As for the hardware the psone has a single 32bit CPU along with 2mb of system memory and 1mb of video ram
The NDS has a 32bit Arm7 running at 33mhz alongside a 32bit Arm9 running at 67mhz and had 4mb of unified system memory

All in all there is a lot more to emulate when it comes to trying to get a DS emulator going not to mention having to code things like the 2 Video outputs and a touch screen input along with the normal button inputs so there is a lot more complexity required on top of the additional hardware.
