Hacking Porting playstation to Wii

[mastermanna123]

END OF PSX ON IPHONE DISCUSSION.
Now back on topic...

 

[davidw89]

Thanks mastermanna123..nice Grand Theft Auto on iPhone ; D..but i am sure a Wii processor is stronger than an iPhone right?

Point taken Trolly, at least this guy is giving it a go. Even if he fails to port PSX to Wii, at least he tried

If anyone wants to "donate" head over to the forum ; D

 

[ProdigySim]

Am I the only one suspicious of his need of a Modchip to make homebrew?

 

[Lumstar]

You probably will need a modchip to read original PSX discs, if Wii can. It hasn't been proven whether or not Wii reads CD-ROM media when modded.

The iPhone has a 600MHz ARM processor (or PPC..not sure)

 

[Jacobeian]

No, he has made psx, gba, gb, snes, and other emulators for the iphone, as well as some for Gp2x. He really does know what he is doing.

sure he did, "his" emulators are initially GP2X ports of famous emulators (snes9x, gpSP, picodrive from Notaz, psx4all from chui and himself)
this work because both machines are based on a ARM processor and a lot of emulator cores already have been rewritten in ARM asm for performance

but the wii architecture is a lot different and the port will not be as easy as the previous ones... My opinion is that he should probably work in team with tehpola/emukiddid .. his knowledge about psx4all (which is based on pcsx code also, with some compatibility improvment) and their knowledge about the wii/gc hardware should make the things easier

a lot of devs already have expressed their will to port pcsx (or derivative work) on the gamecube and now and the wii, nobody have done anything yet ... why ? because this is not as easy as porting an oldschool emulator, because you can't just re-use the original emulator code and need a major rewrite if you want to achieve decent speed, something that not quite any emulator porters can do

uhm, no. a modchip can't magically add an extra laser to read cds.
the wii uses a dvd laser ONLY.

 

[Relys]

But he doesn't need a chipped Wii to run homebrew...

Actually, the lens is sensitive to 650nm, while CDs are 780nm.

Thus, all DVD drives can read CDs. It's just a matter of software support. If the firmware doesn't support it, software can be written to support it.


Though, the more logical step would be to enable the emulator to read ISOs and load 8 games on one DVD.

 

[Lumstar]

In that case, someone should write an audio CD program. Wii is one of the very few disc-based consoles in history to not include software for it. PSP being another, obviously.

I don't even own any CDs... not even data ones.


Wouldn't MP3 via USB/SD be more practical in this day and age?

 

[Lumstar]

Yes, I agree there. I'm a bit surprised there hasn't been much homebrew for that.

Then again... An SPC player would be more interesting to me.

 

[teq]

I used to know a good site that converted all of the SPC audio to MP3.

Lens is sensitive?

How about those are the wavelengths of light the laser uses?


QUOTE

Can DVD drives read homemade CD-R and CD-RW?
The earliest DVD drives could not read CD-R and CD-RW discs because of the difference in the light wavelength used for reading the discs. Regular CD-ROM drives use a wavelength of 780 nanometers (nm) to read discs, the same wavelength required by CD-R and CD-RW discs. DVD uses a wavelength of 650 nm. Regular mass-produced CD-ROMs are very reflective and can be read at a variety of wavelengths, so the 650 nm is not a problem for them. However, CD-R and CD-RW discs are not as powerfully reflective at other wavelengths, and a 650 nm laser has trouble reading them.

http://articles.techrepublic.com.com/5100-...11-1047035.html

It goes on to explain that standard multi-read drives are equipped with separate lasers for CD and DVD (780nm and 650nm respectively). The Wii is only equipped with a 650nm laser as far as anyone knows, so it's not likely that any reliable CD reading can be feasibly done.

What's more, the sector layouts for CD an DVD discs differ (MODE1/MODE2), and this interpretation is usually done in drive firmware. (For a well known example of this, Wii discs use an entirely different sector layout and can only be read by drives which allow RAW disc data reading, like LG drives) Since there is no 780nm laser on the Wii, it's not likely that the firmware contains functions for reading MODE2 sector data, although it is possible. If there was no firmware support, the two choices would be a modified firmware and mod chip incjected code. Since the firmware is currently stored in a ROM on the disc drives, a custom firmware would not be possible. Mod chips injecting code might be possible, but at this point they only send a few basic commands... I've heard that the debug port interface is hardly enough to actively patch data, and I doubt the drive allows any sort of code-adding feature.

So, sorry, CD-ROM is looking pretty much impossible for the Wii.... Unless the 780nm laser magically appears.

 

[teq]

On the contrary, there is an algorithm in which the same 650nm laser can be used on 780nm pits. The disc is spun at twice the speed it would usually run at and each pit is read twice from two focal points.

It was introduced primarily to store more data on a CD-R than is feasible with a normal CD-RW drives.

The practicality of this algorithm is slim to none, with the advent of inexpensive multi-format DVDROM drives and DVD-Rs.


Like I said before, DVDs with an emulator that supports ISO is the best solution.

David, watch your thread count and where you're posting threads.

The information in your threads is slightly better than SamSam12, but you're posting as many threads as he used to.

Also, this should go in the General section, not the Hacking section.

YOU'RE

Uh... stfu.

A moderator would've told him the same thing, considering the day he posted this thread, he also had 5 other threads on first page.

 

[Shuny]

It look likes moderators didn't punished him / moved his topic ...

That's because nobody responded to his other threads, other than to tell him to stop posting so many.

They disappeared quickly. Had they not, people probably would've gotten more annoyed.

well the Wii doesnt support DVDs either

im sure theres a reason Nintendo chose to do this

it wasnt designed with the idea of all-in-one media player like the other two systems out there

and why would someone want something so simple anyways? you have a computer to play CDs on
