2d PSP
« on: October 03, 2011, 12:02:16 pm »
Is it possible to emulate 2D PSP Games (atleast simple games) on the dingoo?

PSP: 333 MHz with GPU
Dingoo: 400 MHz without GPU
Got it?
Sorry guys for not caring about dingoonity lately. It was nice to be with you, and maybe I'll come back, but not now...

A machine needs to be several times more powerful than the machine it wants to emulate.

Simple answer: because there's no PSP emulator for the Dingoo.

But how would you want to run psp games on the dingoo? Totally skipping the hardware differences, the screen resolution doesn't match. And applying a software scaler would decrease the speed from 0.0001fps to 0.0000001fps :)

It depends of the software scaler. One which would drop pixels could be extremely fast, and a game running at 0.00010fps could drop to 0.00009fps, but not much slower. But I believe you were speaking about a bilinear filter, which would indeed be extremely slower.

Well while the 2D games may look like they do not require much, they are still coded and programed for the PSP and so still take a lot to Emulate.

For example take old system like N64 you need a higher spec PC to Emulate and play Duke Nukem 3D on N64 than just running Duke 3D for PC yet both games are near enough identical. The same goes for years ago when Doom on PSX emulated on PC took much more spec than Doom on PC yet again the games was near the same apart from the sound and music etc.

What i am saying is metal slug Anthology psp would take too much for the dingoo to Emulate as its coded for PSP, yet there would be no difference in the games graphics and sounds to the Arcade roms that run well on Dingoo, same goes for say trying to Emulate the Sega Megadrive Classics for PSP on a Dingoo yet the SMD Roms would run fine in a Emulator

The GPU debate is not the main one, as maybe the PSP would not hardly use it for 2D

The problem is usually when your emulating a system that is 333Mhz your gonna need a lot more than that to emulate it, this varries from system to system emulated. But i would imagine that even a Dingoo with double its Spec would not Emulate the PSP even if it had say 800Mhz CPU

Of course the PSP uses its GPU to handle 2D too.

Yeah that true...

I guess my point is a lot of the 2D games are not that intensive to do as far as hardware drain, in other words they would not use much of the GPU and a sytem with higher CPU could do the job...

But as the games are coded for the PSP Hardware it would make the game much harder to emulate.

so like i said playing Metal Slug 2 PSP if someone gets a PSP Emulator for future homebrew consoles would run a lot slower than the Metal Slug 2 Arcade rom, yet both games when playing (apart from few options) would be near enough the same thing.

In a nutshell the bottom line would be that i dont think any homebrew handheld would emulate the PSP to a good enough and playable level, maybe the Pandora could but how many people own them.

If games that were first developed with certain lower-end consoles or arcades, are ported with the PSP, shouldn't there be a diff in technical output as the ported game are optimized for the psP's hw which is a higher in spec..

F &KK Off, it's not that I can't understand why such hardware can't ever emulate sonycrup, it's that I have little knowledge on gaming handhelds recently as I'm still learning crap. .. and I thought dingoo was a decent handheld with almost the same hw on the psp, and creating emulators was crap coding. So, bs, if we can get the source code, whichj will nvr hppn, crap may work with extensive mods.

It's simple. The dingoo A320 has a internal, single-cored JZ4740 CPU with 400Mhz stock clock (running at 336 default) and NO GPU AT ALL.

The Sony PSP has a 333Mhz MIPS, single-cored CPU, backed up by a nVidia GPU.

To emulate a console, handheld, device, (put name of electronic equipmente here), you need at least 3x Times the processing power of the emulated device.

If you dont know what a GPU is:
A GPU is a chip/processor created especifically and unically for graphics and physics processing. If a device lacks such a thing, like the A320, then generating 3D graphics is a hard and slow task.
What's more, a 2D game CAN ALWAYS(or not) use special effects that ONLY A GPU CAN PROCESS OR CREATE.

For example: Blur (can be done by processor, slow), Shadows (Slow on CPU too), Shading (Pixel Shader, cant be done by processor), Vertex shading (same as PixelShader), Water reflections (hardly done by processor).

Did you get? I'm not explaining that again.  :-\

What about a PS3 emulator for Dingoo?

Also what are the chances of a Crysis port?

I'm already working on PS3 emu, I'm getting like 0,00000001 FPS but I think with some optimaliztion I can reach 0,000001 FPS. If you don't believe me, well then you're right.

I've done a quick mock up of a Dingoo running PS3 games. As you can see from my picture it's totally capable of running Just Cause 2.

Hopefully this puts an end to all those negative devs who refuse to spend their spare time coding us awesome emulators!  ;D
