GP32 A Good Pc Emulator


Blah said:
Well unlike nearly every other modern architecture, the x86 architecture is a CISC architecture, meaning that it has a large, complex instruction set. The simple fact is it is more work to write an emulator for x86 processors than others.
Modern x-86 processors are very risc like. Furthermore, just about ever emulated processor is a cisc processor and not a risc processor. There are a few risc processors that mame can emulate (but VERY slowly), then there is the ppc emulator used to emulate ppc macs, but they are terriby slow. From what I understand, it is VERY difficult and slow to emulate a risc processor with a cisc processor. I think it has to do with the number and size of the registers (at least that is the case of emulating a ppc with i386).

I would love to see a new PC emulator where you will be able to select CPU processor just like WinUAE selects from 68000 to 68060. If it's also aimed for speed, I beleive we would be able to run those 286 classics preety well. The problem is who's gonna start working on such a project? I for once were dreaming of start coding but this will probably happen in 2015 from my side ;P
 
A PC emu aimed for speed could be doable, to handle games of the 80s likely; PocketDOS (closed source shareware on WinMobile) works pretty well (much faster than DOSbox, but less compatible too, and less features) but runs best up to 600MHz.. still, at 200-300MHz it can pull off a few 286 games, depending on the year. You're not getting EoB1 on 200MHz, but you can get Duke Nukem and even more advanced stuff just fine.

I started a DOS emu years ago and got so far as XT and such working before I ran out of time; someday I'd like to pick it up again and work on 286 and XMS/EMS memory and all that, but it'll be awhile yet.

Once Pandora hits, though, I'll see if I can bust my ass into coding again. Anyone know when Pandora is coming?

I believe the WIKI page said something like april/may, but I suspect that its speculation.

I, for one, think that is a really optimistic forecast being used to stifle gp2x growth. Few people want to buy a new system with another one just around the corner unless it's at fire-sale prices. It's funny, a company finally gives the community what it says it wants, and then abandons them pretty quickly despite supporting the community with new (as in not used) consoles and new designs every few years. Could it be better, probably. But trying to be everything to everyone usually ends up not working because it doesn't excel at anything. So, Pandora will probably put the nail in the coffin for Gamepark and probably fall apart itself leaving us with nothing.

I think its a little different than how you discribe it. The guys making the Pandora are primarily the distributors for the GP2X in europe, as far as Ive seen they havnt stopped selling them. I expect they wont stop either. Basically it comes down to this, if the Pandora guys drop it after it releases and they cant get anyone to by GP2X, GP32 then thier out of a job. So with the risk's they are taking, im sure they are going to make sure it succed's to the best of thier ability and they arnt going to release a piece of junk. You forget these are the guys that have help propel GP32 and GP2X to the state they are in.

I strongly disagree with the statment that Pandora is trying to be to much and thus not good at anything. All your aluding to is the fact is has mutliple user inputs. As I see it as long as they are placed in a usable manner then how does it hurt? If all you use the DPAD and the buttons then thats all you use. The extra stuff isnt going to kill you and it doesnt effect the system to be there. Its not like the Pandora is trying to cook your dinner and play games.

Finally lets get this out there the Pandora design is not that complicated. It's a SOC! Basically that boils down to plugging everything into the main chip and most times the manufacturer will give circuit diagrams. The GP2X is the same thing. I believe the most difficult part of the design is meeting EMC requirements.

I agree with this point, but most people and reviews don't. For us classic gamers the KB allows us to use software for classic computers, but other people see the keyboard as an intregal part of the design. So it (the KB) get s reviewed on the merits of the kb. Since the kb isn't very good as a regular kb it ends up being a negative point at least in the review.

This machine is basically a small pocket computer, not a pocket game system. It's in the price range of a small pocket computer, has the capabilities of a small pocket computer, looks like a small pocket computer, has the touch screen, ports galore (and I really thing the power cord needs to be moved to the back), a kb etc... The problem is, is it's not a very good pocket computer and a very powerful game system can be had for less (like the PSP).

Finally, I really don't have anything against a new game system, but I feel like the GP2X is not even close to being tapped (at least for home brew games) and still has an untouched core for almost all of the emulators. Most of the emulators could get a significant speed boost by using the second core. There are lots of people buying gp2x's now (the new version), but lots of people are being put off by a piece of hardware that is supposed to ship in the spring and most likely won't. Summer starts in 5 months, spring in 2 (march 21). When you take into consideration that not much usually happens in the spring and summer in the video game industry, there is really no point in pushing for a spring release when most sales happen in the fall. To the best of our knowledge a final proto has not been made and carved in stone. This stuff takes time and I just don't see it happening in the spring. I COULD be wrong, but it just doesn't make much sense, especially when you consider that the spring is historically not a good time to release a new system. Even in our little microcosm of the market, many of us got our machines as presents (I got my gp32 as an xmas present. Look at my join date)

We have RIGHT NOW a fairly capable game system that is pretty good, well supported (for the size of it's market) and it's being abandoned for something that isn't even here yet and most likely won't be here for 8 or9 more months (if at all). So lets be happy with what we have RIGHT NOW

I really don't like the fact the GPXX forum (meaning the website as well as user forums) are being used to push the Pandora. We wouldn't like it if Sony were using this forum to push the psp. This webpage is for Gamepark video game systems (I mean, it is called gp32x.de) and I would like to see it stay that way. It's not my decision, but being part of the community I have as much right to stick up for the GP2X and GP32 as someone else has a right to push the Pandora (which isn't even out yet) with the exception of the website owner and I would think that the site owner is interested what the members think.

Who's reviewing it? No one has one yet, it's all just reaction to the design. Wait for some people to actually use it for a while.

It isn't actually that black and white at all.

christo930 said:

No, UMPCs cost at least two to four times what Pandora does. It's more in the price range of a PDA/PocketPC (which despite its name is NOT a pocket computer) or tablet web device like Nokia N800.

christo930 said:

And has the capabilities of a handheld game machine, including dual analog which no other handheld has. You can't just ignore the gaming controls.

christo930 said:

No, it looks like a DS with a keyboard instead of a second screen. UMPCs, PDAs, and what have you look nothing like this.

christo930 said:
has the touch screen,
DS has a touch screen and it's the most successful handheld on the market right now, maybe ever.



christo930 said:

Ports are par for the course for a platform like this, of course until it's out you can't really say anything. What do you expect?

And the power cord will be in the back. Even if it were in the front (like the PSP...) that'd be a million times better than having it on the SIDE like GP2X.

christo930 said:

No, the problem is that people such as yourself are seeing a design that is different from what you expected and are not willing to give it a chance. Yes, it's true that this aims to be more than just a gaming device but there's no reason why that should take away from it being one as well, and the keyboard can aid in gaming. In fact, a number of the people interested in it want it for emulation of old consoles, no matter how much you think that this isn't why it was put there you can't deny that it's beneficial for this. I'll be the first to admit that the design might have led to some compromises in how the gaming controls work (particularly touch screen, which is probably not going to be that heavily utilized anyway), but until we actually get to use them we'll have no idea how it pans out and we don't know exactly what the final revisions will look like either.

"Very powerful" is entirely meaningless. Is GP2X "very powerful" too? Because it's less than the PSP. No matter how powerful you think either is, Pandora will be the most powerful by far. This is progress.

What do you know anyway? It's really easy to point at emulators and call them subpar but the work necessary for parallelizing them to the point where it can run on the 940T is anything but trivial and will most likely give far less of a benefit than you're anticipating in most cases. The lack of cache and shared bus means that it can easily cripple 920T performance as well as performance of the video subsystem which is also sharing the bus. Not to mention the fact that the 940T doesn't have an MMU, so it becomes a real pain sharing code and data between the two since they're in different address spaces.

Despite the fact that game consoles tend to have parallel components they more often than not rely on a degree of high synchronization, which can often be to the point where it would negate parallelizing it in emulation.

That's just unfounded pessimism, I think you're eager to slash this thing because you're bitter about it.

Which is a totally different market that's ramping up for the winter holiday season...

This is ridiculous. I'm sure they won't have that much problem selling the initial batch regardless of when they release it. I don't think people actually make all their purchases in the fall. Getting this out as soon as possible as good thing (so long as quality control doesn't suffer)

You're basically just repeating the same sorts of things a lot :/

If you look at what people are saying here I think it's pretty obvious that most of them plan on buying this themselves. This isn't a child's toy, the demographic is entirely different.

Who is abandoning the GP2X exactly? Are you going to blame a lack of development on the Pandora because you're disappointed with what isn't being released, when your expectations are unrealistic to begin with? In fact, I would say that the GP2X is overall a very unimpressive platform that's far too weak for its own good and is riddled with design flaws (of which F200 has only corrected one). Saying it'll take 8-9 months is completely contrary from their intentions, and saying it won't be out at all is just incredibly pessimistic. But I am pretty sure you want this to fail so people will focus on your precious GP2X instead :/

Now you're just being petty. Despite the name I really don't think these forums have any brand loyal to companies that have "Gamepark" in their name. Comparing Pandora to the PSP is preposterous and you should be ashamed for doing so. Pandora intends to be a platform for enthusiast developers which more upholds the spirit of what GP32 and GP2X were than they did. If the site owner is supposed to care what the members think then you're on the losing end of this because you are by far part of the minority.

I think you're just bitter because Pandora isn't what you expected it to be and rather than live with the fact that GP2X was never going to see the kind of amazing performance you thought it would you'd rather blame something else for it. Pandora is what people want. GP2X's strengths lie more in a community that has a strong desire to make it succeed than in being a well designed platform.

The dev of Mini vMac announced he'd move on to Mac Classic emulation so I asked him if it would be good enough to emulate Apple A/UX and he said no cause then he'd have to implement PMMU emulation and that would make the whole thing impossibly slow. So it's indeed not all just a matter of 10x the clock speed.
