Nintendo DS Emulation Hits the PSP - DeSmuME Test Release

[sappo]

Posted this on qj.net, posting it here:

"Yeah, someone finally ported DesMuME to PSP and the newbs are just going wild over it. "omg everyone said it couldn't be done but someone did it and we sure showed you!" I could have told you from the start that this could be done - actually, I was nigh certain that someone would eventually do this. Does that mean that it qualifies as "DS on PSP"? Not at all.

Unfortunately no one seems to understand that this will never be fullspeed, and the compatibility will probably remain terrible. People think that porting an emulator is a big accomplishment - well, it isn't. 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!"

Yeah, I always thought that you were great. Now I have the certainty.

And, GPSP rules That's a REAL emulator, not this strange and useless thing.

GO BUY YOURSELF A DS, if you want to play it :P

@ALTIMITHacker
Static recompilation for DS games? On PSP?
ROOOOOOOOOOOOOOOOTFL! :rofl:

Finally someone with sense in this thread!

Cool for you to double-register, ALTIMITHacker :P

Your quite the negative type Exophase. I didn't say such an emulator could be created easily, in fact, I clearly said it would take the skill of Sony itself. And with the increased RAM, it would be nice to load the image onto it directly, which may not fit on the older PSP models. I know that you like to see it as a challenge and therefor run away saying "too much graphical emulation, can't be done", but clearly it can.

You too are a coder, and you should realize that under the right program, almost anything can be done, though highly unlikely. Im not one to say that since it has lower specs, it can be emulated easily. Im one to say that since it has lower specs, it is possible to emulate it. You have to understand that what homebrew developers sometimes go for is the understanding of progress achieved. It is normal for people like us to try and create that perfect program even though its viewed as a dream. This would definitely be a far reach from reality because like many have said, this is something that would be extremely difficult to emulate at fullspeed. But if the developer wants, he can go for it. There is nothing wrong with it, considering that it is possible to emulate. I feel that it is possible to emulate at fullspeed, which im sure you can not accept because of how unlikely it is. But that is something you have to come to terms with.

Exophase: I must say it is Shame On You for being angry with someone who ported this. Why would you turn a blind eye and be furious? Have you gone mad? This is the type of thing that leads to a dead homebrew scene. Spoiled users. This person didn't even advertise the release that strongly at all, it was just picked up by QJ and it hit the news from there. In some ways, I hint jealousy from you. Not because he ported this, because it is true that anybody can port this to a PSP. I hint jealousy, more exact, fear from you because you know that a real coder could pick this up and decide to start one from scratch. If than happens, it could have great potential, which you so strongly argued was impossible. Sometimes your wrong Exophase, but you can't try to prevent being proven wrong. That just makes it all the 'Wronger'. lol

Lets try to keep the flame to a minimal amount. There is no benefit to saying that "it would be so hard to code, it is impossible". Like V3N0M said, it would be interesting to see how far this emulator could go.

Ya...I don't double register thank you.

lets just see what happens in a few months to see if this goes anywhere..

Agreed ^.^

I cant really believe some of you guys who been visiting this site. You all have been eagerly posting or awaiting for others to post stuff for the handheld. Maybe some of the stuff here isn't as good or polished as the others but it's the community that keeps everyone coming back or at least the fact that there some people actually posting stuff that others could for free. I thought people here encouraged each other to make things possible that wasn't entirely "feasible" or "impossible" to begin with. So when I see all this bickering over something that's supposed to be an "expiriment", it makes this scene seem like it's full of people who just piss on anything they don't like or can do themselves - which I know is not true. I would like to think that I bought and kept my PSP because even though it wasn't exactly the killer handheld on release, it was the possibilities generated by having such an strong homebrew community that kept system users interest between big releases. So to see people stomp on a release even when there are design challenges (doesn't it sound like a PSP?) won't keep me surprised if we don't see progress from other people to advance "ports" into other things. Things that we might find real cool to have, like a DS emulator on the PSP. And if not, so what? It's really not like anyone's paid for using it or hearing about it's release. Did some of you forget that some people supposedly have left the scene because of this same thing? Some of you should really lighten up. Sorry to everyone else who took the time to read this post.

I don't think other coders quit because of flaming, but nobody can really confirm that besides the coders themselves. But Anyway, what you say is true. Im getting the feeling that this place is turning into QJ, they just don't appreciate anything anymore, always negative.

only time will tell for this project, it seems pretty useless, however give him the benifiet then rolf at him when he fails, theres more inprtant things on PSP Deadaleus is coming along great and GPSP ^^Exo

Your quite the negative type Exophase. I didn't say such an emulator could be created easily, in fact, I clearly said it would take the skill of Sony itself.

I'm realistic. I'm saying it's probably beyond feasibility altogether.

And with the increased RAM, it would be nice to load the iso onto it directly, which may not fit on the older PSP models.

First of all, images of DS games are not ISOs. Second, this isn't useful - do you know why? Because unlike GBA Nintendo DS games can't see their game media in the address space and have to explicitely load it. This takes the cost of a load from the card so having to load from the PSP's memory stick instead is a negligible difference.

I know that you like to see it as a challenge and therefor run away saying "too much graphical emulation, can't be done", but clearly it can.

How do you know that clearly it can? You claimed full speed, that's all this is about. Just because you keep saying it's possible doesn't make it so.

You too are a coder, and you should realize that under the right program, almost anything can be done, though highly unlikely.

No, as a coder I have never believed that. This isn't winning the lottery, feasibility is much more discernible, something is either possible or not. Sure there's a lot of grey area where people don't know, but this doesn't really fall under that.

Im not one to say that since it has lower specs, it can be emulated easily. Im one to say that since it has lower specs, it is possible to emulate it. You have to understand that what homebrew developers sometimes go for is the understanding of progress achieved.

I feel that it is possible to emulate at fullspeed, which im sure you can not accept because of how unlikely it is. But that is something you have to come to terms with.

You just keep saying the same thing over and over again, that you believe it's possible but very difficult, when you have nothing concrete to back this up...

Lets try to keep the flame to a minimal amount. There is no benefit to saying that "it would be so hard to code, it is impossible". Like V3N0M said, it would be interesting to see how far this emulator could go.

Let's try to keep the intelligent deducations to a minimal amount too apparently...

Sure you insist on what you think.

The FREAKIN' RAM doesn't GIVE any BENEFITS to emulation!

Do you want to swap everything in RAM? It's no use. It doesn't speed up things.

Also, you're talking about something EVERYONE doesn't even know about.

The increased RAM is probably an UMD Cache, as it has been said on the PSP Dev forums (where Matieulh and others are).

Also, the only way to use that RAM is by using a firmware that allows access to it. It will not happen, because Sony will not make a two official firmwares, and also, it wouldn't be a wise move to create two different hardwares, it would be a real problem for games developers.

And no, before you even think it, no, probably no CFW will make possible to use it. Because, as many people said, there are probably two mirrored 32mb RAMs instead of only one, so no luck in using it, as it will not be a single 64mb one.

Why two 32mb RAMs? Simple, because in doing so, developers don't have to touch nothing. Memory addresses will be the same for PSP Old and Slim, and they won't have to touch the second RAM.

And please, reserve that "---------------------ALTIMIT has spoken." only for you

Oh, and remember, I'm seeing forward to see the next version of this emulator from you, seeing how many good dev ideas do you have

Hey Sappo:--------Altimit has spoken

Cool. At least you haven't replied with another crazy dev idea for this emulator

yea i kno dat daedalus is more important ATM but gpsp? when was the last time he ever released anything.. at least to the psp public and not gp2x. seriously, we r all dying for gpsp 1.0 or 0.9.5 ...

at least someone is doing something. y does everyone have to say "o this emulator is crap, its not gonna go anywhere, it doesnt work, the coder just wants attention, it will never work not even in a million years, its a port and it will never work, buy yourself a DS if u really wana play" WHY DOES EVERYONE CARE SO MUCH IF THEY THINK ITS GOING TO FAIL! the coder is doing this as an experiment and we should all respect him even if this emulator doesnt go anywhere, he made PSPTUBE didnt he??? yes we should thank him for that. there is nothing wrong with people being curious of how far this can go. so....

Spoiler!

STFU
