Open PS2 Loader Project - v0.9

It's just a warning about an unused variable, that couldn't be much more minor.

Quick question, shouldn't the games be loading faster over SMB?

I know my connection supports 100mb\s on the lan, and my HD can do at least 30-60mb\s, but it seems about the same as before(ie, from disc) speed wise. ?

I have port forwarding setup, but maybe it's not quite right, I've forwarded the port to my PC's IP, do I need to do anything else, maybe forward back to the PS2 as well, or setup port triggering?

I've also noted weird activity, I'm seeing numbers that don't match what I setup in OPL, I have an IP monitior, and the access is happening on different IP's than I setup. (ie, I never, see the IP my PS2 is supposed to be using access my PC. Nor the proper port.)

OPL rev404 SMB (SlimPS2)

Any thoughts?

Edit:

I tried port triggering, and I did see the right address, and port, I guess this is right. I didn't see any real change in speed though.

I wish I could say the same here.

For some reason all my attempts to use VMC on USB consistently fail.
And I'm using exact copies of VMC files that work fine with the SMB and HDD cores of OPL.

Maybe someone could upload you a VMC maker and OPL compiled to see if it is your compiler.

I already have 'VMC maker', and tons of working VMC files for my games too, as used with other cores. (And with HDD core of my v7 nearly all games work with VMC.)

The problem with USB tests before r428 was simply that the VMC code for the USB core was bugged, which crazyc fixed in r428.

But your point about my compiler setup is still valid, as it does seem as if my elfs behave differently in some respects from those others compile, indicating some difference in the libs used to compile them. And comparison between my elfs and those of some other developer might be a good way to pinpoint the cause (though still difficult).

Don't worry about it, that's benign. I'll add a cast to make it go away later.

Have you seen this post? http://psx-scene.com/forums/showpost...postcount=3337 (Open PS2 Loader Project - v0.9)

My setup was also working perfectly with USBA-format games but when I added the CD and DVD folder it stopped working.

Hope it helps.

Best regards.

Hi bateleve,
Thanks, I have seen your post and already tried your suggested changes to smb.conf but unfortunately they do not cure my issue.

My issue is a little different as the USBA games are still working with the existence of the DVD folder, it's just OPL is not showing any of the games in the DVD folder.

Thanks anyway.

Edit: Now that I've worked out the proper naming convention for ART this is now working from my NAS, so it's just the DVD/CD folder that is now not working (Haven't tested THM).

In theory, yes.

But unfortunately, the PS2's I/O hardware isn't fast enough to maintain the bandwidth capacity of 100Mb/s.

Not only that, but many of the drivers available for the PS2 are definitely not well built (for speed).

This is very true. One of the most efficient programs of all for fast transfer over LAN is the HDLD_svr server for installation of games to an internal HDD of a fat PS2. The 'safe' TCP versions of that server can reach around 2MByte/s (16 Mbps) while the UDP-only server is supposed to reach over 3MByte/s (24 Mbps), but I never got that one to work right.

For normal file transfers I usually get the uLE FileBrowser to copy stuff over LAN to internal HDD at rates of a little over 1460 KByte/s (11.4 Mbps) but for most other usage the effective rate is controlled by how you need to dispose of the transferred data. So if you are copying data to a USB drive instead, or to PS2 MC, then the transfer rate will be much much slower, as those media can't accept data written at a decent rate. The best of that bunch is probably a USB HDD, but with the PS2 USB interface and drivers that won't write much more than around 150KByte/s (so 1.2 Mbps).

No specific rate can be stated for gameplay reading the ISO over LAN though since that depends entirely on design details of the game itself, and what kind of data caching it implements between the raw cdvd read operations and the final disposition of the read data (for graphics rendering, audio effects, and whatever). But we can at least be certain that the average transfer rate will be lower than that of the fastest pure HDD game installation servers, and such speed can only be expected as momentary transfer peaks, since much of the data disposition methods require a slower rate anyway, not to mention the loss of CPU time (both for EE and IOP) due to all other work involved in running the game engine.
