similar to what bleemcast did for playstation on dreamcast emulation, (can someone explain on how this works?) would it be possible to do the same thing for example by running a 360 game on a ps3. i know its wishful thinking but it was just something i was wondering since its been done before.
I don't think so.. For one, the PS1 and Dreamcast were a generation apart in both time and hardware while the PS3 and 360 are nearly equal hardware-wise. It just wouldn't work.
wouldn't that make it easier? being that they are both in the same generation? Or does it need to be that the stronger system would be able to run the weaker system's games?
It will make it 1000x harder. To emulate hardware (via software) you need some serious horsepower and a lot of development time. That's why we only have "near perfect" emulation of most consoles up to 16-bit and basically Playstation (although I've never tried the latter). The other machines require a lot of horsepower, and a lot of time to refine. The horsepower is there, but the time hasn't been. Even when we see good 360/PS3 emulation (playable in 5 years, good in 10?), you won't see one emulated on the other. It will only be on the latest hardware. For example, look at the PSP trying to emulate the DC. PSP is far newer hardware. It's just not strong enough.
The Ps3 and 360 have roughly the same power, in total. They achieve similar goals via different manners however. Emulation by definition needs more cycles on the host machine in order to emulate the hardware of the second machine in question. With this example in mind, the PS3/360 wouldn't have enough cycles available to it in order to immitate the behaviour of the other.
not to go to far off topic on my own thread but at some point in the future by way of home brew or official patch would it be possible for a non b/c ps3 to play ps2 games. beats me how it can play ps1 games ( i assume with out the ps1 hardware built in). I know the 20 and 60 gig versions have the emotion engine built in, however the ntsc 80 gb achieves this through software emulation without the emotion engine. is there hope for my 40 gb to one day play ps2 games?
Nah, a PS1 emulator is easier to do than one to emulate the PS2. Not to mention, PS1 emulation is a known world for many years now, while the PS2 still isn't fully emulated, not even on a ultrapowered PC. Emulators are more complicated to work on than most people think.
It already is possible as the 80GB PS3 has PS2 emulation. However, it's pretty shoddy (again, what I've heard, not tried). Considering that Sony has access to all documentation and then some for the PS2, they're going to be able to write the best emulator. It's unknown whether they've given it their all or not. My guess is not. Another good example to illustrate would be Xbox emulation on the 360. It's good, but it's not perfect (depends on the game), and these machines are a full gen apart... the latter w/ far more memory.
Saturn emulation is relatively good these days too. What I've heard is that you need approximately 10 times the clock speed of the emulated console just to emulate the CPU, which would kinda make sense considering the emulated consoles at the moment. Of course, there are the Jaguars and Saturns that are a nightmare to emulate considering their deviant architecture (and the PS2 is also quite a mess architecturally), and you also have to consider the varying efficiencies of different CPU types (see also: Megahertz myth). For example, even though the Xbox has almost double the clock speed of the GameCube, because the GC processor uses a much more efficient RISC architecture than the x86 architecture used in the Xbox (and all PCs since the 80s), the difference is not as big as you would think.
SSF010 on the PC is one of the most accurate emulators I have ever encountered, and it's for the Saturn. It plays everything I throw at it and sticks really close to the original feel, down to the scanlines - no fancy user-selected resolutions on this emulator. You also get pretty precise emulation for most components, so it runs all/most games of the saturn perfectly!!!!! The speed is also fully playable on my setup, with everything turned on maximum accuracy.
What's your PC spec? The last one I had (a somehwat old P4 3Ghz setup... pre-Core) chugged. I had to play w/ a frame skip of 1 which killed it for me. I might try it again, but I don't like the fact that it doesn't support the Arcade VGA card. Scanlines are nice, but allowing user-defined resolutions isn't that hard. Keep in mind though, SSF's author is amazingly dilligent. He's been working on it for years now, where most would've just thrown up their hands.
Indeed, an unrealistic feat as previously thought, but a single man's dedication has proven otherwise =) I recently bought a "cheap" computer. I tried fitting as many good component as my budget could afford though (500 euros final price, tax inluded) I have an ASUS mobo on the low-end side of things, so a single PCI-E and 2x ram slots, populated by 1066 Mhz effective-able RAM modules (ie 533Mhz real speed - their original speed is 800(400mhz) but they re called 1066+ because they re made for the purpose of OCing them - this is important because making sure you have a 2:1 ratio between RAM and FSB does make a whole lot of difference, it's like gaming on a console effectively in terms of gameplay, because everything is correctly timed so caching is minimal) I have a Core 2 Duo processor, 55nm Wolfdale at 2.93 Ghz, and an ATI HD4850 graphics card (got it on offer for 65Euros). Mind you, my setup can run Unreal III at 60+ stable frames per second with everything maxed out - it didnt break a sweat however while using the Saturn emu. Please note that SSF makes good use of multi-core processors so there's no surprise there. Naturally, the first game I tested was non other than Radiant Silvergun (sorry for the cliche) followed by Panzer Dragoon Zwei and Azel - all stellar games running as they should. Uru ruins in Azel never looked so nice in the sunset
I should bust it out again. My PC is somewhere in that realm, accept I have the latest AVGA (which is based on Radeon HD2100 or some shit). I need to look that up. It's hooked up to an Arcade monitor, so all that stuff really doesn't matter. If I need to "compute" on it, I just use VNC.
