Hi can anyone create or tell me about a psp game emulator for nds
thanks
#140297 - calcprogrammer1 - Sat Sep 15, 2007 3:08 am
Is this supposed to be a joke?
DS:
66MHz ARM9
33MHz ARM7
PSP:
~200MHz somethin-or-other
Even in just that respect, the PSP is twice if not 3 times as fast as the DS, that's not including RAM, and assuming a ported game (emulation takes MANY times the power of the original system). No, there is NOT a PSP emu for DS, and there never will be (even the Genesis is hard to emulate on a DS, let alone PS/PSP).

so with 66+33=100Mhz, an emulator would run at half speed, right? :p

Not even close, because the CPU architecture of the two aren't the same. For the most part, emulating a system with such different CPUs requires around 10x the processing power of the unit being emulated, so just to interpret the PSP code, you'd need about a 2Ghz processor. Then there is emulating what the PSP can do, such as graphics, sounds, etc, requiring even more.
Face it. The DS is NOT gonna be able to emulate the PSP, ever.

I know of one PSP emulator for Game Boy Advance, but it only plays two games: Lumines and part of Smart Bomb. You will need a SLOT-2 card to run it though.

tepples, you amaze me, no matter what the topic is, you always find a way to advertise your game, do us all a favor and do what a normal person does, and put it in your signature.
disco stew, it is called sarcasm lol
psp speed can hit 333mhz, but it also has support for things like floating point
anyway, PSP emulator on the NDS would be completely worthless, other then for a learning experiment

The PSP is very powerful, but how to emulate two screens, one of this a touch screen on a PSP with only one (not touch) screen?

Actually there already is NDS emulator on PSP. It is far from being finished, and it runs software at 3-4FPS if run on 333Mhz enabled PSP. It will probably never be fast enough to play games. Not to mention the lack of touchscreen.
On the other hand there is touch screen mod for PSP too, to bad nothing really supports it.

Though, for several DS games you don't need the touch-screen at all, like Mario Kart DS or Tetris DS.

Isn't that 2x333mhz (in theory, in the commercial sdk you're forced to use a lower clock?) That's quite a lot more than 66+33 mhz :P
#140407 - calcprogrammer1 - Sun Sep 16, 2007 4:57 am
I don't own nor care about the PSP, therefore I don't know it's specs, just it's somewhere around there from what I've heard. Nintendo always wins.

1 processor at 333, and only commercial developers were limited to 200mhz in the beginning, now they have access to it completely iirc, the homebrewers had access to it for a while

Not even an even a Paint Shop Pro 1 emulation? owww :(

No, the PSP has one CPU
Are you thinking of the GP2X ? (2x200mhz I think, but they can be clocked higher)

The PSP has 2 processors. 1 CPU, one "Media Engine". I couldn't tell you the clock speed of the Media Engine.

From the wikipedia article on PSP:
| Quote: |
| The secondary CPU present in the Media Engine is functionally equivalent to the primary CPU save for a lack of a VPU. The MIPS CPU cores are globally clocked between 1 and 333 MHz. |
edit: formatting ;)

access to the media engine was limited I thought, but it could be as limited as the arm7 is on the DS, I dont know, havent got too deep into PSP coding yet
