PS2 games on the PSP

[johncrosby]

Hello. I am working on hacking a variety of playstation/android/mac systems and thought of an interesting concept: a PS2 on the PSP.
In order to do this, the PSP has to have an older custom firmware.
This process will take approximately 64 Gb of memory.
1) install Windows Vista onto the PSP following this link's suggestion: google: windows vista on psp
2) Install PCSX2 onto windows Vista: Google code: PCSX2 svn (current revision is 5076)
3) Install Windows Visual C++ , Nvidia Graphics Nforce, and any other visual enhancing program, as I can't remember the entire process at this time
4) Purchase a PS2 and Games to legally acquire the bios and the roms,
5) Mont the games and files onto the Vista Portion of the PSP harddrive
6) Load PCSX2 and run games including codebreaker

This is a theory that I would love to test once I pay off more of my college debt and can afford the sd card large enough to hold the massive Vista updates and Games.
If anyone can try it and get it to work, it would open a new world of gaming to an about to be dead system.
Again just a theory, but I hope this works.

While the idea is nice i doubt it would work at all. the PSP just isnt powerful enough to run sucgh content efectivbely. first off you are EMULATING a PS2 on an Emulated Windows install. first off the windows 7 program will run very slow at best secondly trying to emulate anything under such a system would slow it down that much more. If you wuish to waste the money to try be my guest but I can already assure you that you will fail to get anything running smoothly.

It would be easier to convert the PS2 software into PSP eboots. The PSP is simply too weak to run any OS other than its own. Ever try using Windows 95 on PSP? Its a pain in the ass.

Windows 7 would be a bit much, and programs only run smoothly on the windows Vista 32 bit operating system. 64gb memory cards would also not be a waste even if it failed because I own more games than that on my actual PSP, so it would just alleviate the use of the UMD, saving battery life and processing power. It would not be an Emulation on an Emulator however. It is a direct installation of the operating system. Unlike Wine or Darwine, you are not running a windows application through a application, you are running a C++ or Java program natively on the operating system This is how I run a Ps2, Wii, Psp, and all lower consoles on my mac to Begin with. I install the complete Windows Vista operating system on the Mac and run all the emulations I want at full speed with full resolution. In fact, once everything is set up, it only takes about 5% of my computer's processing power. Comparing the stats on my computer to that of my PSP, 5% of my computers processing power/ram constitutes only 25-50% of the PSP's capabilities. Hence, it is not impossible to do nor would it take too much power for the PSP, as long as the programs are coded and supported Properly. The only thing stopping me from figuring it out is finances funding the card, again because college bills and a family to support, I try to be thrifty.
See, because the native operating system takes 40 gbs to set up properly so the psp becomes a full functioning Windows Vista Computer, i think the space required is the only Hard difficulty. Another problem becomes the Nvidia graphics needed, I don't know about graphic card in the PSP right now so I would need the matching Nvidia driver. I post on the forum for others to purpose different solutions to the end goal of a portable ps2 that plays psp games as well without hardware purchases.

I have only seen others use Windows Vista Running as the root operating system and it ran at full speed, I would be interested in trying it myself to figure out what makes it slow and see how to improve it if it does run slow, but I do not have the funds till later. The eboot is another great option. I was hoping by now someone would have cracked the internal coding to make eboots run as if they were a psp game, however I have monitored the type of work required in getting full isos to run smoothly and I do not have the skill to eboot it. If someone has figured it out, I would love to get it to work myself.

It's difficult to get the PS2 emulated on a PS3 without hardware. How could it possibly be done on a PSP?

[scarmullet]

When you compare the specs of the two systems

PSP
CPU: 222mhz
32mb RAM @ 2.6 Gbit/s
111 MHZ GPU

PS2
CPU:299 MHz
RAM:32MB
GPU:147 MHz

The PSP is too slow to run PS2.

[johncrosby]

I must disagree. according to Sony and IGN specs the PSP has
CPU 333Mhz
Media Engine of 333 Mhz
2 Graphic cores:
one for 3d engines and one for Rendering and Surfaces at 166 Mhz
32Mb RAM
GPU: 2 MBVRAM at 166 MHZ with 32MB main RAM and 4 MB DRAM

The psp has the power without over clocking, though I think the .Eboot method would be better than my original idea.

[RandQalan]

This all a great idea but do you know how to code for psp and about the PS2 enough to even attempt this
BTW I really hope so

[indirect76]

Despite the fact that the two systems have similar specs, they have different CPUs and GPUs. Full speed emulation is simply not possible. This business of converting PS2 eboots to PSP eboots sounds far fetched as well. I don't mean to piss on anyone's Whaeties, but that's how it is.
