all loading no nonsense loader for PSP

They're the same thing, one's just faster.

I've recently seen Pro Duo and Pro Duo High Speed :?

The High Speed is a tag on branded Sony MS Pro Duo sticks, that doesn't appear on all. That suggests there's an even faster variant to me. Anyone know anything about that, I can't dig up much with a quick Google :?:
 
Yes, Sony and SanDisk have released higher speed versions. But as I asked aerlier, is there any useful difference for PSP? Sure for realtime video-capture that performance boost is welcome, but does a cheepo MemStick function just as well on PSP as an expensive one?

i think the top bitrate of 1500Mb/sec for H264 provided by most psp video encoders is a tad above what a non-pro ms can provide. anyways, for a definitive answer you can ask archie4oz ; )

more like a brainfart :? 1500Kb, 'fcourse.

1500kb/sec will not be a problem for read speeds on flash media, even old cheap ones.

from my experience 1000Kb/sec was the approximate practical maximum of the original (non-pro) memory sticks. though that was on a humble 33mhz cpu palmos4 device. come to think of it it'd be a good idea to actually measure that under more clean conditions...

*runs some test on an old ms over a usb2.0 ms reader (sandisk)*

1.0044 Mbytes/sec

ok, so i was off by a factor of 8 8)
 
A meg a second is crazy... that's only 16 minutes of video on a 1gig card. That's DVD quality video.

Higher speed mem sticks don't make any noticeable difference to PSP.

mech, once upon a time when the world was a better place the lower-case 'b' stood for 'bits'. so that codec bitrate being 1500kb/sec translates to ~180kbytes a sec.
 
darkblu: No need to get condescending mate :) Check your post above mine where you directly mention a megabyte/s - which is what I was replying to.

Also, flash memory cards generally get around 2-10megabit/s, so when you said "from my experience 1000Kb/sec was the approximate practical maximum of the original (non-pro) memory sticks" I assumed you meant kilobytes. I haven't ever seen a flash memory card only get 125kbyte/s.

Secondly, that whole thing about whether a small b or big B signifies bytes or bits is bunk. EVERYONE has their own standard, in my Computer Engineering degree lecturers varied all the time. I agree it should be a standard, but no one can agree.

i wasn't : )

yes, but that was raw transfer rate, not some codec settings.

understandable. apparently the particular flash card interface and what stands on the other side of it make a difference. but those 1000kb's did seem a bit low to me too so i bothered to carry out that test over a usb2 device.

that's why the whole 'once upon a time' which sounded condescending to you - it was more of a general rant than enything else. believe it or not up until the late '80s early '90s people tended to generally adhere to the small-b/capital-B notation much more than they do nowadays. but with the advent of the industry that got lost, and sometime in the early/mid '90 a recall a journalist from a well-respected IT magazine posting an editorial on how he didn't feel compelled adhereing to any standard in his articles - at that moment the notation had already gotten into the shambles it is in today (kilo-what?).

I know... I was pointing out that if anything even went near the limits of the memory stick duo, it'd be insane and useless :)

Oh and it totally shits me as well that no one will agree on a standard for writing bits and bytes... I tried really hard at Uni to stick to one standard, but everyone just kept changing it! I had to give up in the end and accept that most network/bandwidth stuff was bits, and most other stuff was in bytes :) So yeah, i feel your pain.
 
Couldn't be arsed to start a new thread on this, hopefully someone will pick this up..

So, anyone have any idea if a loader for 1.51+ is in the works, or if anyone's even close to finding an exploit? Wouldn't be so interested otherwise but naturally my brand new PSP has 1.51 firmware :) I want them emulators damnit!
 
for the moment absolutely no news regarding that...
but on the other hand, team xcutor has made a flashdevice (they told they wont release it ;) ) that will upgrade / downgrade your firmware. most probably these kind of things will come out in the future when europe has his own share of psp users.
more users = more sales i presume

right now, i must say quite impressed by Hue and PCE (pc-engine emus)
I only play emu games these days, don't even have any psp game
 
The only PSP game I really liked so far was Dynasty Warriors, the rest has all be emu and viddies for me. (Re-watching "Bits of Fry and Laurie" whilst waiting in doctors offices is a HOOT! :D )

Well, considering the recent legal actions Sony has taken against importers, and previous actions against PS2 modchip makers, I would hold back on releasing it as well :)

Oh well, just have to be patient then.

Well I'm totally addicted to Lumines and Wipeout Pure.. for some reason the missus isn't too happy with my PSP ;-)

Is there a C64 emu for the PSP yet? :) I wanna play M.U.L.E. in the tram!
 
Didn't want to start a new thread on this, but spotted this on www.psp-spot.com:

Yoshihiro has now informed us he would like to tell the public that he has been able to downgrade 1.51 and 1.52 PsP's to 1.5. Yoshi has said that this will be released September 1st. The explination he has given us/public for not releasing it yet as it's still buggy and there is some risk of it bricking the PsP. Hopefully in the next 5 days all the bugs will be sorted, and we'll have a stable downgrader. So for all the frusterated 1.51 and 1.52 users, don't upgrade yet! The next week is definitly going to be interesting indeed..

Here's one 1.51 owner hoping this is for real :)
 
It seems from what I read somewhere on the web that sony will open up the PSP for homebrew development anyway sooner or later (and it seems not that much later), so hopefully we'll soon see a way to run free software without resorting to downgraded firmwares, dirty hacks or bug exploits.
