because i dont see any of you trying to develop a NDS emu for PSP.. dont take coders as a joke. sorry for my words before Exo.

like exophrase and others said its impossible to function problary , dont get me wrong it would be cool if it worked but so would rigging the lotterty but it aint gonna happen

hmm? not any time soon.

Yeah Exophase, you're right. DS will NEVER run at full speed on PSP. Only stupid people thinks that this DS emulator is a big deal. It's USELESS, as you said.

And, anyway, WHO WANTS DS ON PSP? I mean, DS have the touch screen, wich will never be emulated by the PSP. This is so useless that reminds me the "periscope in the car" at one Seinfeld episode. :-D

And for the dude who made this emulator, why not spend time making a great Genesis emulator instead of wasting your time?! Just to be an attention whore?

I forgot to say: GO BUY A DS! :-) It's a great console!

to make psp emus you have to make it from scratch so you take the pc out of the equation.

THIS SPECIFIC emu has no chance of getting any farther than a title screen.

I don't get that logic. It was my understanding that this was a port of the emulator, not an emulation of the PC version. As in, the source code was taken and modified to run off the PSP, sort of similar to Daedalus but in a much more basic form. I agree though that it won't get up to full speed anytime soon.

Because porting something is easier than making one from scratch to tailer the hardware.

This was better when it was an april fool's joke :p... no really though its a good accomplishment for any coder to do such a thing, but I have to agree exophase on this one. Anyway congrats on the port but, please try and develop it to a better working emulator.

even if full speed cant be reached at least we have a nds emu.. even though it doesnt work lol.

then i declare i have made a Virtual reality emulator which i brought back from the future, hmm i made it one day... yea erm yea i made one day when i was out fishing yea thell never suspect a thing hehe , get to the point, its pointless,

I have also started on a Wii emulator which works, it doesnt play any games and it moves slow, but by god it works, yet again i lie

just throwing this out there. if a ds emu comes out that works good im gona have to say i told u so.. :p

dude if it comes out i,ll hold my hand up but until then

it ****in flipinn possible for a full speed nds emu just takes time!!!!! like the ps1 wasnt possible and n64 wasnt possible >.< and there is away for touch screen
hold a button and use anloge stick

Do you mean if THIS emulator works good? If this emulator runs 50% of the games out there at 20fps, I'l hunt down a rabid lion and kill it with my bare hands. Then I'll cut off it's head with a plastic spoon and send it to you in a box.

If you mean "if a DS emulator coded from scratch that works good comes out 3 years from now", you get nothing!!!

:rofl:

EDIT: Like I (and other people) said before, the DS has two seperate screens... Each of which has it's own processor that is close in terms of power to the ONE in the N64. Emulating the DS is like emulating the N64 twice over (unless you only want one screen).

When it comes to this stuff on PSP the accomplishment is in getting it to run quickly, not to get an existing emulator (that struggles to reach full speed on a PC..) to run on it. DS emulation will NEVER run well on PSP, and this emulator in particular will probably never even run a fraction as fast as it could.

To whoever ported this, shame on you. You probably just did it for the blind attention, which you're very much receiving. You should know full well that you haven't actually accomplished anything."

Hopefully no one HERE will be ignorant enough to respond to me "oh yeah? look at gpsp!"

Great post Exophase with the exception of one thing. Why did you add that last line about gpsp hahaha. That would have been priceless to see someone say that.

i know its hypethetic but either is fine with me but u still have to kill the rabid lion with ur bare hands :p

That's my problem to deal with :p.

erm look at gpsp .................................................. .................................................. ............................................

ITS F**ING GREAT :thumbup: "ahem golden sun :( TLA" lol cant say anything bad about this emu:) :) :) :) :) take some smilies, smilies attack :) :) :)

He added that bit because it already happened.

It's DS Killing DAY!!!!!!

think about a flash mod psp slim it may work
or if we hack the psp slim finally to do custom firmware


by the way how fast is the ds ram
the ds to me is a crappy version of n64 but still won't mind having a ds

ds homebrew probly work on it to

but like i said before . if this emu ever gets better which i hope it will then shame on all of you just dissing the emu and dissing the porter/developer himself.. because i dont see any of you trying to develop a NDS emu for PSP.. dont take coders as a joke. sorry for my words before Exo.

Your saying it like it can be made over night and NDS on psp is pretty pointless just go buy one.

Second post... ever at DCEmu, and first thing I gotta say: LOOK AT GPSP! :p




...someone has gotta say that, no? Well, anyways, you've told me this a bunch of time, and I know you are right. Right now, I'm thinking... "you're right". :)

DONT WASTE YOUR LIFE MAN

ds emulator? nice u can convert code...now EDIT IT

no i dont think that at all. read this, it was on page 2 of this thread. and im thinking on buying a DS someday wen i make money

he probably will edit.. this isnt going to be the only release u kno..

Exophase, could DS emulation could be achieved with ARM7 emulation being handled by the Media Engine and the PSP's main CPU doing the ARM9 emulation? Would it still be impossible to reach full speed with this setup?

Come on now, lets not flame each other over this, it's fun that someone ported it, we all had our say now let's just get on with it.

personally thats how i feel as well Emeriastone. whats done is done :)

The Media Engine is not that powerful... :p

The Media Engine is as powerful as the main CPU, they're both MIPS R4000 processors clocked at 333 MHz.

well strmnnrmn is trying to get the Media engine put to use for his N64 emulator. if he succeeds when we get to know how powerful the M.E. really is

Exophase didn't use the ME in his emulator mainly due to the fact that it wouldn't give that much of a boost... and here's another example: SNESTYL ME version is only slightly faster than the normal version.

Edit: And it's a core... not a CPU. There's a difference.

i tought it was more like duel core cpu where the me runs @ 111 mhz and the main cpu runs @ 222 mhz i could have been miss led tho and the me only decodes media.

The difference is the ME is only being used to handle sound emulation with the SNES emulator, while the DS has two CPUs that are each doing way more work than the SNES's sound chip so ME support would give a much bigger boost. Also the GBA only has one processor doing all the work so using multiple processors to emulate it wouldn't make much sense.

I don't really have much confidence in it... the main CPU is a huge burden, and synchronizing the two would be a pain (they share fast, cacheless memory). The video alone is at least 2x as demanding, but probably often more (especially with 3D). You could perhaps put the sub-screen on really high frameskip.

I don't really know what DS game code is like either, IE how much it pushes the CPUs. Since it has instruction cache it might be that proportionally more code on the ARM9 is ARM rather than Thumb (unlike GBA), which means more work in emulating. And the memory emulation would probably be more complex because the memory subsystem is more complex. I can get some average load games to use about 5ms per frame on PSP - multiply that by 4 and it's 20ms, way above the 16.7ms per frame you need to be fullspeed and with nothing left over for graphics. Don't even want to mention the heavy load games (urgh, FF6)

gpSP's speed isn't always maxing out the PSP, but a lot of the time it could definitely use a more free CPU time. It's not that it's 100% optimal but I personally only know of so many ways to make it faster, and not an awful lot faster.

Exophase,if you used ME in ur GPSP, would the speed increase?

Maybe, but it'd take a lot of reworking.

Oh and... off-topic: You wouldn't believe this, Exo, but Riviera works on 0.8 beta... with the faulty BIOS, although sound is broken. I almost never check back here so I didn't know about those three games... sorry.

Exophase is right, ports of emulators are going nowhere even more it the emu struggles to get fullspeed on PC

lol this would be a first a current generation hand held being able to emulate another current generation hand held. even though it would be sluggish emulation

it is pretty kool to know that the psp can emulate a lot of systems including its rival console

well still it would be awesome if psp could emulate snes and n64 and of course ds at full speeds. that would have to be a Christmas for psp users
