Open PS2 Loader Project - v0.9

[barf]

Ya, it´s the same as the ps2. still running at 1.1 speed.

How come? PS3 is choking the PS2 libs to PS2 speeds for compatibility reasons?

[WiiPower]

It's because the loader is using usb1.1 drivers. To get the speed from 2.0, you need 2.0 drivers. 1. Nobody has usb2.0 drivers for the usb hardware of the ps3 when it's in ps2 mode. And 2. most likely usb2.0 support is shutdown/disabled somehow in ps2 mode*.
It may be possible to get usb2.0 speed there, but there's a big if for it. And then it's pretty much work to write an usb2.0 driver.

*My knowledge about ps2/ps3 is very limited, most likely somebody here has a definative answer for this already.

[barf]

Probably shut off by the hyper-thing.

Open PS2 loader rev 129

Game: Black
SLUS_213.76

Confirmed working with r122 on SMB and USB as someone else posted in the compatibility lists.
But the game freezes using rev 129

If anyone else who confirmed it working on r122 can try it using r129 too see if they get same results as me.

That's very strange since nothing has changed in core since r122...
But don't be afraid, it seems it's compatible with the next-release core:

About the Mac-related discussion a few pages ago : I know it's not a proper solution but you can run USB Utils without any noticeable problem through Wine...

[sonix]

Ok, I ripped my original Rez copy (PAL) with USBExtreme, my results:

USBAdvance/Open PS2 Loader USBA 0.41: Works fine
OpPS2Load 0.41: Pink screen to white and freezes
OpPS2Load 0.5: Pink screen to yellow to white and freezes

What's wrong?

Well thats what I thought, so found it strange as to why it would freeze. I will play it again today and see if I get same results or not.
Maybe its my rev, will remake it and test again.

UPDATE: Ok I recompiled r129 and BLACK now works fine.

[Bootlegninja]

I guess I need to compile the newest revision soon. Hell, I haven't even been able to test the public release yet.

[WiiPower]

jimmikaelkael don't worry, i will stop nagging you now. Whenever i post something, you can safely assume that's it's not directed at you.

*Udated*

Stupid patch(to slightly speedup network loading):

List of changes to original code:
- Replaced a loop that processes all received data with memcpy(->tiny speed up)
- Changed the buffer sizes to 4096 and 8192(->tiny speed up for mode 2, big speed up for regular mode)
- When receiving data, it writes from the 2nd packet per request on directly into the output buffer(->micro speed up for mode 2, tiny speed up for regular mode which is finally faster than mode 2 now)

Sadly i still don't get smooth video playback with this on the game i tested. I only got from ~52 seconds to ~39 seconds from start of a certain video till a certain point.
