HD Homebrew Project Developement (Old Thread)

Many useful PS2BIOS related thing can be found nearby at http://ps2dev.psx-scene.com/
And PS2BIOS dump tool can be found there. I used it to dump rom0 via PS2Link. But DVD player is not there, it's located in encrypted rom somewhere in rom1.

well doesn't the driver for DVD play load from the MC once it is installed (with the update)? So could one just have the app rewrite this driver there?

I'd love to help with testing and some dev (teaching myself C/C++) but I just moved and my PS2 got some major abuse and won't read any CD/DVD discs... tried cleaning and realigning the sled but look dead to me...

I don´t know if transfer files betweeen PC and PS2 are slow (0.7kbs) because everybody are using a old source to make transfers using ExecFTP, Ps2vfs, hdl server... but if possible to transfer files from PC to PS2 using full ethernet capacity is possible, it can be a good upgrade. It is possible?

And any possibilty to support DVD5 and DVD9 movies?

My earlier post says it all: not likely, too much effort and beyond the scope of the project. I would rather work on getting PS1DRV working with the HD than DVD video playback, and I am not quite good enough with reverse engineering to be able to say that I could get the PS1DRV working.

On the slow transfer speeds, that can likely be explained by how the I/O bus in the PS2 works between DEV9 and the rest of the SBUS. 0.8MB/sec is pretty good (About 10Mbit, once overhead is accounted for), and realize this: When reading from the network to the HD, you read data from SMAP, send it over the SBUS to the IOP, and then send it back over the SBUS to the ATA bus (through DEV9 again). It is hardly surprising that the network speeds really suck, especially if you sync things up after every read and write. The connection to DEV9 probably isn't that great.

yes i have a modchip as you can read from the signature, anyway non ps2disc are being detected as dvd video and at boot up as not valid ps2 disc obviusly and psx games as psx games also before bootup, anyway hdl detects them correctly as not valid

Gran Turismo 4 NTSC USA - rental
Disc Read:
validPS2: Yes, discType: DVD, Dual-Layer
Layer Break: 1317056, Total Length: 2594960

This is interesting, because this hints that GT4 is actually pretty small (5GB roughly). It would almost fit on a DVD5 by itself.

HDL does more extensive detection than I do currently, so of course it will be more accurate. I am just returning what the PS2 claims the disc is, plus my extra detection for DVD9 discs.

UPDATE:

I got proper access setup to the CVS server now (the build bundled with MacOS X 10.2 is broken, whoops), which allows only anonymous read-only access through the pserver. If you have a unix-like (Linux, BSD, MacOS X) environment, or the command-line client for Windows, you can checkout the latest source with the following commands:

cvs -d :pserver:anoncvs@mzed.homeip.net:/usr/local/cvsroot login
(It will ask for a password, just hit enter)
cvs -d :pserver:anoncvs@mzed.homeip.net:/usr/local/cvsroot co HDDemolisher

If you use a graphical client, the server is at: mzed.homeip.net. The user is: anoncvs. There is no password (blank) for the user.

I have taken measures to ensure that this machine can remain available, and secure enough that I can be confident in making it public. Do not abuse the server, or I will wind up taking it down and finding some other way to host it. Be good.


ADDITIONAL ADDITIONAL:
Another thing you can find in the CVS tree is the latest ELF builds. Under the dist/ directory is the latest build I have produced before committing changes to the CVS tree, so it will always be as recent as the source code available.

If we can install Final Fantasy XI Online on the HDD and run from the HDD without the disc using a Final Fantasy XI Online copy and a modded PS2 (Matrix or DMS), okay, we will have the problems to connect, but I´m just talking about installation of FFXI Online and execution from the HDD, why we cannot execute programs like HDLoader from the browser? The only way is having ELFs hidden for the browser and executing from Memory Card or hd0: using DMS Explorer... Why not execute from the browser if with the ATAD patch from the modchips, it is 100% compatible? I hate that.

No.

[spawner_brasil]

No.

Sorry, but for me it is lack of ability.

what do any of your questions have to do with any of the development going on in this thread?
