Project 64 On the iPhone...?
 
Hey I was just thinking about how cool it would be to have a Project 64 app on the iPhone. Apple would probably not approve of it being an actual app but you could make it underground and able to work on unlocked iPhones. :cool:

sorry, never going to happen

It is possible for someone else if a latest source code is released on project end, but with time narrowing down options to priorities such as continued stability and functionality (and some other features also wanted) tense requests like that lose chance in the hands of the creators.

One of the greater difficulties would be re-engineering the hardware interaction between both the iPhone and the emulated such in all major processes. Because analyzing source code worked on for years by someone else is risky for proper maintenance and dangerous for bug-fixes and what is currently under work: It is probably wisest to leave portability to others who are interested. If this project was less famous this would all be less tense.

Uhm... would an iPhone's hardware even be able to support this?

HatCat 22nd February 2009 07:18 PM

It shouldn't be impossible to try? There are memory emulators that run on other handheld devices.

Obviously three-dimensional geometry is not supported by the default iPhone. Maybe it would be possible to modify your own device (likely re-manufacture) and engineer your own rendering device to install to it. In the long run it would probably be best to just port Project64's graphics plugin simply by redesigning on yourself that gives null video output or configured maybe to just translate active memory into pixel maps...I guess that's what zilmar's CFB plugin does?

also very sorry should have noted the 1.4 source code is definitely an option, posted like it wasn't

Does it have enough processing power? If it's anything near that of the DS, it's impossible. Then again, saying that, the DS can't even browse the net, so I'd say it's worth a try.
But, I don't think the PJ64 team should bother with it, they have enough on their plate. Maybe some other dude out there will?

If you want, just ignore my bumblings on about the DS :)

HatCat 23rd February 2009 12:24 AM

Right as I said.

And of course I don't know. If it is not obvious I simply try.
But I don't think processing power really narrows down possibility. We know the DS is not well emulated? Basically there is only non-commercial support. Generally even the DS has speed issues in emulation where functional; there are bound to be extreme counterfactors apart from procession durability.

Just don't do any graphics rendering. Either manufacture a form of the device that supports it or just have a plug-in that gives no rendered video output or possibly just CFB output. Basically we agree that this would be disappointing if done.

Heads up!
 
Here are the iPhone's specs:
CPU 620 MHz ARM 1176, underclocked to 412 MHz
GPU: PowerVR MBX Lite 3D
(The GPU is able to support 3D geometry isomapping)

Now I have some experience with the iPhone's SDK but as Iconoclast said before, it would be quite difficult to convert the C format programming of project 64 to that of the iPhone's when I didn't write the program in the first place. However, it is not impossible especially if I had help.

The main problem lies with the graphics plugin (As Iconoclast said before). A likely solution to this is to simply port over a plugin such as Zilmar's. But it might be easier to simply write a new one adept to the iPhone's specs; this would probably be best since the iPhone app will be a dumbed down version of the original.

Either way this is getting a lot more attention than I thought it would so it might not be such a long shot after all.

hmmm

Well if PJ64 was made to support linux, then it is possible it can be adjusted for this portable emulator. I wonder how well this would actually work;)

HatCat 23rd February 2009 03:53 AM

3D geometry isomapping? If I understand this phrase correctly I think it should be possible to emulate via wireframe rasterization (where you see the edges and vertices of the geometry just not the faces), and then it may even be easier to add on some installation that will map textures to faces from TMEM.

Converting between languages is another story since C other 3GLs they just translate to assembler operations to the same result (a binary) so the porting would be more challenging in adjustment to the hardware's ability to emulate another target rather than the current language used to describe it. At least that's my first thought...hoping I'm not missing something critical in what you imply.

@Mdkcheatz the hardware probably becomes more primary to this concern than software like the operating system, but the engine considerations to a Linux port of Project64 today are called Mupen64Plus.
