No doubt my five year old X86 PC could emulate a Sam440ep with AOS4 in 60fps.

The CPU on Sam MBs are about as weak as on the nintendo gamecube/wii game consoles.

The question then is whether AOS4 could run applications just as well through emulation...

http://s1.postimg.org/ose4zycfh/Dolphin_2015_04_10_14_24_32_20.png
Soul Calibur II running 60fps v-sync in 1080p 4xAA and 16xAF. (warning. large file)


But what's the point emulating Sam/OS4 really? What has OS4 that I don't already have on the PC?

Quack III I've already had for fifteen years... It gives around 800fps in timedemo benchmarking so that is out of the question.

Anything?

@Hillbillylitre

Is there a name for this "not teh original Amiga" version of Godwin's law yet? I mean, EVERY thread the last year has derailed into this (and the "should be ported to xxx architecture to survive, a point which I would personally think is mutually exclusive with this "not teh original Amiga").

We use AmigaOS because we like it more than Windows.

Simple as that.

As far as I know, there is no demand for Duck simulators on AmigaOS.

What kind of answer was that? Should I interpret the answer like the only thing is the OS itself?

Pay a insane sum of money to only get a very bad OS when you can get five high-end machines with an up to date OS for the same price plus a huge selection of software to choose from.

Is there any demand for AmigaOS4 then?

Commodore Amiga computers have a historical reputation that can not be changed nor achieve today. That you for your personal feelings and money greedy people trying to suck money out of this is sickening to watch, not only because you are like ticks on the system but also because I feel a bit sorry for some of you.

So it is you who is trying to derail. The Amiga finished its run in 1994 so get over with it.

Well, I thought this was a forum dedicated Amiga computer systems although it seems like fake imaginary Amiga systems have most importance here?

hmmm... pay more money to get an OS WE LIKE or 5 machines with 'modern' restricted OS's WE HATE that require far more resources to run as responsivly.

I'll Stick with OS4 on my incredibly expensive X1000. For anything I can't do on it I have my phone or a 10 year old PPC mac which I turn on maybe twice a year...

You sound like you're a moobunny refugee. The Amiga lives so get over it.

@HL

I'm sure you're very familiar with this site since you've been observing it from moobunny for quite some number of years now.

As a reguistered AWN member, there is no obligation for you to post in threads related to NG Amiga or, as you prefer to say "fake imaginary Amiga", if that's not what you're interested in.

If you feel that there isn't enough discussion related to your own usage here you could always try EAB. They have a dedicated WinUAE section there.

ROFL!

Ok-ok-ok. Just one more post in this thread and I'll get out of here.

If you don't want to use Windows there is always the Mac if you want a more expensive and less functional system, and there is Linux if you want a cheaper system.

but, at the end, is it so difficult make a ps2 emulator for Amiga indipendent if or how it works?

Right now nope ... in future probably.
when gallium will be release and if a good programmer will start make conversions from Xbox 360 ... Wii, GameCube, Dreamcast , Nintendo 64, NDS will come on AmigaOS

About Ps2 the major difficulty will be implement the jit core of the Ps2 cpu did for little endian ... and only a real good programmer can swap to big endian.

I can't recall what, but I hit a wall with both Dolphin and pcsx2 when trying to port then to AROS a little while back. Was a big lib that I couldn't compile if I recall correctly, but its all a bit vague.
Resources are always going to be a problem though for ps2 emulation. Pcsx2 utilizes a fair bit of multi threading, as well as being pretty GPU heavy. Even on systems where its CPU and GPU resources are used more optimally (windows/Mac/Linux at times), it still requires a reasonable machine. My AROS box for example, on the odd occasion I boot Windows on it isn't enough for full speed on most games. While its aging now a core2duo@3.86ghz, 3gig ddr2@1200mhz, and a 1gig gf9600gt, under Windows will give performance multiple times what any amiga-oid system can touch, or even hope to one day touch in the case of ppc amiga-oids, for something like pcsx2. AROS on x86 is probably the only option that could offer playable results, but I suspect even then games will have to be selectively chosen, as some games are heavier than others.


Dreamcast on the other hand seems surprisingly light in regards to required resources.
Probably a more useful/realistic target for the more modestly specced ppc systems.

gallium is already done on AROS, so PS2 emulator i think will run :)

For some games, it'll probably be pretty good, but as I said, even on Windows where multiple CPUs are used, and gfx drivers are 2x as fast as gallium+mesa (for conversations sake, in reality it varies) a 3.86ghz c2d + gf9600gt isn't enough for some games.
Being that the abovementioned system is my AROS desktop I'm expecting to be somewhat limited as far as games that run full speed are concerned when/if AROS gets a pcsx2 port.
I'd still love it to get ported, but Ive used it a bit over last few years so am pretty familiar with its requirements.

It's not the endianness. To write a JIT you have to know both the host and the guest architecture well. The JIT has to emit machine code for the target CPU, you can think if it as translating from MIPS assembly to PPC assembly.

@BSzili

yes , insnt my intention speak about endianess is really difficult for my poor english explain in right way :P
In any case jit is the difficutly ... or some one have to take the mips code from qemu e inplement in the pcsx2 (like the job did for winuae). but we know qemu is not fastest way and need great cpu power... probably the P6T on the 5020 will have the power for this emulator without jit and with qemu core.

Okay, my bad then. WinUAE is not a very good example here, because it had no PPC emulator before. In PCSX2 you already have a CPU core. Ripping it out and replacing it with an other one with a different interface might not be trivial. Take Mupen64 vs Mupen64Plus for example. The interface of the CPU JIT changed a lot, so I can't reuse the code from the XBox360 or Wii port "as is". A good portion would have to be rewritten so it can be used with Mupen64Plus.
