PSP Emulator?

Lets say we're somewhere in the future and the RFOM exploit proves successful an we can run homebrew. Would there be enough resources to emulate a PSP on PS3?

Re: PSP Emulator?

I think yes!
I mean from the resources...
Cmon its a 8cell CPU, 6 for games?
-i think yes, its possible.
But the biggest question is: Is it possible from the programing side?
I don't think that is possible!

Re: PSP Emulator?

it is possible, but we just dont know how to do it yet. whats needed is a psp emulator then it could be done via linux. but as for the ps operating software its one for the future.

Theres an open source PSP Emu for PC on PSP-hacks that cant run 3D graphics but it can run in 2D. Ive heard some 2D games run pretty well.

Re: PSP Emulator?

Yea it can be done, don't know whether it would get done, then again, they did just about every console for the PSP. The PSP emulator was first developed by Sony for beta testing of games and to help game developers. I think a PSP emulator for PS3 would be cool and I'd have it if it was good and looked good, like it actually comes up as a virtual PSP like in Home, I wouldn't really need it and I don't suppose many would as I and many PS3 owners already have a PSP.

I don't think that is possible!

The CELL is a NINE (9) Processor CPU:

1 General Purpose CPU, used as the Micro Controller.
1 Redundant SPE for backup in case of a manufacturing defect.
1 Backup SPE should one of the six fail, during real time execution of code, or boot-up.
6 SPEs always available for GAMEs - period.

You are not getting all 8 SPEs for use, only six at any one given time.

This is how it would go:

1 SPE fails continually during testing at the factory, that 8th SPE would be activated -via- a forced blown e-fuse, and would now become an active backup #7 SPE.  That former designated BACKUP #7 SPE now becomes one of the SIX always standard, in use SPEs.  You now have one SPE that is shot to hell, and if one more SPE fails, you're just about done with the CELL, unless the now backup becomes a primary one of the 6 SPEs, and you now have NO backups at all.

-OR-

You have all 8 SPEs in good working order, one fails on YOU. This means the BACKUP (#7 SPE) now becomes one of the Primary 6, while the 8th will not be activated, because it was not done at the test bench.  That 8th SPE is only put in use, if one of the SPEs after manufacturing, fails on the test bench.  This can be done by Sony if you have to send the unit back, because your CELL has failed, but only needs one SPE to get in working order.  They will activate the 8th, as 6th (or wherever in-line it should fall), and sent it out as a REFURB.   They won't replace the Mainboard unless it is a catastrophic failure of any component, or if the Cell CPU has more than two SPEs fried.  The CELL cpu will work with 6 SPEs, and the two others burned out, but no more.

You are misinformed as to the specifics of the CELL CPU, and why it has eight SPEs, and why only SIX are used for games, and what the function of the other TWO are, and you totally missed the Micro Controller, which is a General Purpose CPU like the XBOX360s, but not as advanced.

Re: PSP Emulator?

I have to love some Powerslave-overkill.
Personally, I would've guessed that wg had missed the Redundancy SPEm not the General Purpose CPU.
The power to emulate a PSP is all there.
The software would prove a bit challenging to approach.

I can't tell; are there specific instructions that new individuals follow when entering?
Actually, that couldn't work; they don't follow or read any directions given; it must be instinctive.

Re: PSP Emulator?

It would be possible to emulate a PSP with hardware access to the RSX through Linux.   Some things just NEED to be there to make sure it runs at 100% emulation. 

IF it were that easy, it should have been done already, and we have NO REAL emulation yet...  XB1 has all kinds of EMU with it's 733Mhz CPU, but full access to the GPU.   N64 games are sloppy though...

The power is there, the coding genius isn't...   Remember, when you emulate a system, you need to emulate its CPU & GPU with software, and the more software, the more CPU cycles....  The GPU needs to handle the graphic routines, PERIOD, not the just CPU to emulate a GPU to run good.

Re: PSP Emulator?

We just need a Dark Alex for the PS3. In all seriousness it is possible but not in Linux unless the RSX is hacked. Being a slim owner with a big screen tv and a component out cable it is unnecessary.

@Powerslave....it gives me lulz the detail you give sometime.

Re: PSP Emulator?

Powerslave with the upgraded cpu and ram (in the xbox1) does the n64 emulation run better? or is it the coding or gpu?

there was access to the rsx in 1.9 i think but they patched it up. not sure tho if it was full acess

The XB360 has THREE (3) cores in the CPU.  The Cell has NINE (9):

1 General Purpose
8 SPEs (2 backups: 1 MFR defect, 1 for real-time failure) 

AS we see, there are still no worth while linux emulators, because of the restricted RSX hardware.

People keep griping about it, yet you won't see them doing anything about it, because they CAN'T, that meaans; they're not SMART enough, or are lazy and don't know how to code in linux; OR, just want everyone to do it for them...

Powerslave with the upgraded cpu and ram (in the xbox1) does the n64 emulation run better? or is it the coding or gpu?

I never saw that post, but NO, the emulator would have to be written with the ability to detect and use the extra RAM.  So, you have it run either way.  NO one has made mods to the programs for the 128MB, because not everyone will have it, just the "I want that for no reason" people get it...

Re: PSP Emulator?

What i would find interesting though, was for example:

Sometime in the future, if the ps3 gets hacked and we have access to homebrew software. I would really like to see some software that users could run to see IF there playstation 3 has a faulty core. It would test all cores and see if one was blown or all running fine with a backup still in place.

If we get a PSP emulator, does that mean we can play PS1 eboots?

Only with a thermograph...  I saw one, and there are only SIX glowing during game play.  I do not remember where it's at, I tried looking for it for another post somewhere else, but I can't find it.

Re: PSP Emulator?

Yes, that's it.  Look at the PPE, the General Purpose CPU, it's getting more use than the SPEs.  You see six of the SPEs are definitely powered up and in use.  The PPE is the hottest core there, so it is really being tasked, and that's not good, I got a funny feeling about why that is used so much...

Nothing from the Cache, XIO, and nothing from the BEI either...  I don't like the CELL processor man, something it just wrong with the way it's to be used...

Yeah, see this is what I don't like: The PPE, which is capable of running a conventional operating system, has complete control over the SPEs.  It can can start, stop, interrupt, and schedule processes running on any of the the SPEs. To this end the PPE has additional instructions relating to control of the SPEs. Now, unlike SPEs, the PPE can read and write to main memory and the local memories (local stores) of each SPE through the standard load/store instructions. Despite having Turing complete architectures, and here's what I really don't like about the Cell: the SPEs are not fully autonomous and require the PPE to prime them before they can do any useful work.

That puts a lot of load in a single core to control up to eight SPEs...  Not cool..
