Unless ofcourse the original code is one piece of crap spagetti without any documentation. The biggest problem isn't porting it, the biggest problem is finding someone to do it..

Shows what you know.

A couple of facts

1 - The PS3's CPU is too slow for full-speed PS2 emulation - no matter how good your code is. Sony couldn't achieve it either (with their highly optimized codebase that targeted every SPU at the PS3's disposal) and dropped the entire idea - what makes you think a couple of amateur homebrew coders can beat Sony at their own game? So far, their efforts have been absolutely terrible on PS3 - nobody is up to the task of doing this.

2 - A straight port of PCSX2 would have the performance of a Pentium 4 running PCSX2 - that's the kind of 'CPU horsepower' your PS3 has.

3 - Nobody is going to spend/waste his time writing custom Cell/SPU code for the limited userbase the PS3 CFW scene is. For that matter, I doubt anybody is going to write a PCSX2 dynarec for PPC.

No dynarec = terrible performance. Even with a dynarec - there are so many things weighing against this (only 256MB main RAM - only 256MB video RAM - a crap main CPU that has the performance of a Pentium 4 2.4GHz CPU - a weak GPU - lack of decent dynarec capabilities on most PS3s) that this is just an insane crackpot idea.

If PCSX2 will ever happen on PS3 - it will have the performance of a Pentium 4 running said emu. That's it - bottom line - don't waste your time requesting this, don't waste your time talking about it - people that normally would jump up to the task won't bother wasting their time with this.

Lastly,

4) - I think that the PCSX2 team - like the Wii64 team - has pretty much given up on PS3 at this point after the early 'hype' in late 2010 dissipated, and nothing will ever come out of it. So don't hold your breath waiting for the 'official' port. The PS3 is a weak pathetic machine compared to modern-day PCs - the code will run like absolute crap on it.

PlayStation 3's Cell CPU achieves a theoretical maximum of 100 GFLOPS in double precision calculations.

six-core PC processor reaches 109 GFLOPS (Intel Core i7 980 XE) in double precision calculations.

1. And you know how many resources Sony has spend on trying to get it tow work? You know exactly the reason why Sony stopped work on the emulator? Let's not forget it's in Sony's interest to NOT have the emulator working so they can sell the HD collections.. But you're right Sony developers should know more then some 'amateur'homebrew developers.. But then again, see what 'amateur'homebrew developers can wring out of old hardware which no-one deemed possible (like the Philips Odyssee or C64)..

2. Yep a straight port without optimizing would run like **** (just see what happened to valve when they started to port Left4Dead to linux, started out at 6fps, and now it runs at 315fps)..

3a. You mean YOU aren't going to write PPU/SPU code because of the limited userbase. People are writing n64 emulators for PSP and others are writing emulators for even smaller communities.. So never say never, people have written a lot (diffucult) applications which where only for a very small amount of people, there are always people who are interested in getting it to work, otherwise you wouldn't even be able to run your CFW on the PS3 anyway.

4. What do you call a modern-day PC? that's where the problem lies, you might call the latest ivybridge with the highest CPU a modern-day PC, others might call a PC from 2010 still a modern-day PC (or hell even one from 2006).

The chances someone will even try to port the code is slim, but who are you to tell others not to ask or discuss this..

@SuperDre Dont even waste your time with this guy. It seems whenever he posts hes running someone down letting them know just how stupid they are if they not up to his "brand" of thinking.

Homebrew coders are definitely amateurs compared to real professional developers - ESPECIALLY the people in this scene. Trying to deny that is being in denial. There's nothing a homebrew coder can do that a seasoned industry professional couldn't. If they can, they get bought out by companies.

That's why you will find that most of the really good 'emulators' written are often done by people who either

a) work for the big-name companies directly but keep themselves anonymous (like the Quake2x port for Xbox 1, like pSX done by PSXAuthor).

b) eventually get to work for those companies (like Sardu, like Mooglyguy, like zsKnight, and the list goes on, on, and on).

3a. You mean YOU aren't going to write PPU/SPU code because of the limited userbase

For the record, the 'PPU' is just like every other bogstandard processor - there is nothing special about writing 'PPU' code - it's the main CPU and any application you write for PS3 is 'PPU code'.

Second, SPUs are best thought of as specialized vector processors - it all sounds cool that you have 6 SPUs to work with, until you find out you can't really use them for scalar code - until you find out that every time you use them, there's IPC overhead to deal with.

You think you can just wave a magic wand, sprinkle some 'SPU code' around (whatever you think that means) and everything will just run all fine and suddenly slow code magically transforms into fast code? You need to actually have a PURPOSE in your code to be able to offload stuff to SPUs - otherwise you're just going to shoot yourself in the foot and end up with an even slower program.

Unfortunately that's where we are at on this forum yeah - I don't blame you guys for being end-users, but I do blame you guys for not having the willingness to educate yourself.

I repeat - thinking that somebody is going to make a PCSX2 port for PS3 that runs at fullspeed is going full retard - period.

The chances someone will even try to port the code is slim, but who are you to tell others not to ask or discuss this..

Who am I? I'm a guy who has dedicated more than two years of his time to keep this 'homebrew scene' from totally dying out - that's who.

And I'm telling YOU - and your kind - to stop 'hoping' that somebody is going to do this - because that day is never going to happen - and when it does, it will probably run like **** and be abandoned within a few months.

So stop deluding yourself and stop being 'unrealistic' as to what can be achieved.

PlayStation 3's Cell CPU achieves a theoretical maximum of 100 GFLOPS in double precision calculations. six-core PC processor reaches 109 GFLOPS (Intel Core i7 980 XE) in double precision calculations.

I asked mudlord if I should even dignify this crap with a response - he told me not to - but I guess I'm stupid like that - I will try to debate and get you people to become realistic in some way even though it's a waste of time - other people will just call you 'idiotic end-users' behind your back and leave it at that.

If you people want to 'debate' this **** with me, here is what you do -

Get off your ass, stop being a lazy 'know-it-all' end-user, stop playing 'backup games', and start PROGRAMMING for PS3 - that's right, PROGRAM for a change. Start with some ports, see for yourself how well your precious PS3 runs code. Then find out that there's no easy way to run dynarecs at this stage for CFW PS3s - then find out that an LHS costs you 500/600 cycles - then find out that your 3GHz CPU with 'a theoretical 100 GFLOPS' runs more like a Pentium 4 2.4GHz CPU (for the record - this is a CPU dating back to 2001/2002).

It's not about how many double/float calculations can be done per second, it's about how fast your Cell CPU can push all those instructions through its deep, deep pipelines. It's about how long your Cell CPU takes to start resuming work after it trips over an LHS. And to give you a short answer to all that - the Cell CPU runs like absolute crap and ends up barely outperforming a Pentium 4 because of that.

Good luck BTW trying to find yourself a run-time profiler to be able to produce 'optimized code' well enough so PCSX2 will run at fullspeed on PS3 - note - you will have to go buy yourself a DECR to be able to use something like SN Tuner. Thats the thing Math just bought a few months ago - that will set you back a good few thousand dollars at least - and it's illegal to buy for an end-user or for a developer to sell just so people know.

[DEFAULTDNB]

I agree with @Squarepusher2 : its never going to happen, esp not at full speed.

You guys can dream and everything, but its never going to result in anything useful.

Discuss it by all means, but don't discredit @Squarepusher2 , after everything he has contributed.

a Pentium 4 really how can Pentium 4 run games like bf3 or uncharted resistance or la noir

LOL, you're funny... You forget that enough homebrew coders ARE real professional developers during office hours....

but ok, you're the master....... we're not worthy....

Yes, I'm sure they're all coding PCSX2 for PS3 in their lunchbreaks as well.

Last response you idiots will receive. Seems all the people (actual 'devs') that tried to tell me 'don't talk to end-user idiots' were actually right after all.

Wake me up when you idiots will actually start putting some work in, start learning to program and finding out just how good your precious Cell CPU is.

I'm sick if your ugly attitude.

Every single thread you post in usually ends in a trail of battered heads following the long-awaited 'my last response to this thread' post. You know what your problem is? You seem to concern yourself more with 'owning' fellow forum members than educating or informing them.

I'm sick of you treating everybody like they're worth less than you.

Wake you up when we start putting work in? How about you wake US up when you're ready to show our users a little more respect.
