Run ISOs from Ethernet
Run ISOs from Ethernet –
Is there any way to do this?
Or nobody had interested in developing?
I think it would be easier to develop now that we can load games even from USB HDs! The only thing that must be done is to "emulate" the ps2 partition filesystem (it can be done just like they do to emulate NTFS, FAT and ReiserFS paritions from (iso?) images in programs like VMWare, can't it?)
I am only staaaarting my ps2 developing, and I'm faar from having knowledge to make something like this.
But nobody ever had this idea?
(My english can be veery confuse, since this is not my first language. But I hope you understand it :P)

yes i had –
When i saw hdloader for the first time i thought it was exactly as you say, similar to SMS when you play videos from ethernet i thought ps2 could browse the games on my pc (through network).
Strange nobody did that.
If I had enough knowledge in PS2dev for doing that...
It's not that it's impossible, the problem is that the data transfer speed from ethernet is even slower than USB.
This is not true. The Network speed is definately quicker than the usb1.1 of PS2. I have made some speed tests that proved it. I connected the PS2 to my router and measured the speed while playing a movie with SMS from my PC. Also take a look at this Post
I agree that LAN connection may be as feasible for game loading as a USB drive, although my reasoning is somewhat different.

This will also vary widely depending on how the drivers have been optimized, and the throughput potential at 'the other end'. For some old USB storage devices that speed is quite horribly low. Much lower even than what the PS2 drivers limit it to.
The only fair way to compare the real throughput capability is to make some real tests as to what speed you get for the same file being copied both ways. Using uLE this is easy, as it gives both short-term and long-term speed averages during copying.
For copying a 134MB AVI from my USB HDD to the internal PS2 IDE HDD:
Average speed = 505 KBytes/sec with peaks up to 515 KBytes/sec.
For copying the same file from my PC over LAN to the same PS2 IDE HDD folder:
Average speed = 1430 KBytes/sec with peaks slightly over 1500 KBytes/sec.
So for my stuff LAN beats USB by a factor of appx 2.8, which is quite impressive in this context. So all the time delays experienced when launching a game from that USB device could be divided by 2.8 if loading the same material over LAN instead. Except that we have no CDVD emulator capable of doing that .
Of course, there would be many problems in developing such a program, including the hassle of preventing the games and their driver modules from interfering with the Ethernet interface. But the same kind of problem (just for different interfaces) also applies to the existing implementations of HDLoader and USBExtreme, so I'm sure it could be done.

I definately agree with you dlanor. But I think It should be an easy task for the company who developed HDadvance and Usbextreme (they have already developed 90% or more of the project only the lan driver remains). And this should be an allaround solution for every model of PS2. But PS2 is an almost dead project for everyone the money is on PS3 now
What do you mean by "the company".

(eg: HDAdvance is definitely a stolen version of HDLoader, slightly edited.)
The only really good version of such code in a finished product is that of HDLoader (stolen for HDAdvance) and of ToxicOS (the continuation of the HDLoader project by its original author Sjeep and his associates). But these are fully commercial projects and no followups can be expected unless the creators see significant profits in developing such.

That's how it goes with commercial projects, so the only hope for such a development is with an open-source homebrew project, such as the ongoing project discussed in the thread "HD Homebrew project", which could very well lead to a spin-off version using LAN for game images instead of HDD, once the main CDVD emulation hurdles have been solved. But that still lies in the future, so we'll just have to wait and see...

That's all true.
Ethernet seems to be even better than USB for launching games. I think it would be a very good idea for the "HD Homebrew project" to implement Ethernet support for their CDVD emulation...
What I don't know is the progress of that project.
