If the US release will be shipping with v1.5(?) of the firmware and must already have shipped to stores, is there any definitive word on the differences between 1.0 and 1.5? and why isn't it available for download already?

Just wondered is all...

Just going on what's been posted here.

I suppose it's not *definite* that it will be shipping with v1.5, but it would appear to make sense that bugs in the Japanese release would've been ironed out for the US rollout.

The guy who posted about 1.5 being shipped with US psp never replied when questioned about his source or what bugs were fixed. Id take it with a pinch of salt.

bugs wise, there seems to be a problem after inserting a UMD just after system bootup. The disk cant be read. If the disc is in the system at boot up or after a significant time after boot up it will work fine. Literally, its just as you get into the menu, insert the disc. Ive heard that mentioned by others, but I cant remember where.

Other than bugs, im kind hoping they are gonna improve mp3 playback. Its severly lacking when compared with video playback. It needs to be able to skip to a position within a track and to be able to keep the position when system goes into standby. Its not fun when your listening to a 2 hour radio show, only for the system to go into standby while you are talking to someone and having to fast forward at 1x to find your position for a good 10-15 minutes.

Fair enough. I can't say I've run into any other than the psp not liking large pictures, like some panoramic pictures I've taken.

I don't think firmware ver. 1.5 with PSP-1001K will include all the new features that we have been expecting since the leaked firmware found on Internet many weeks ago.

IGN does not have mentioned new apps other than the one already embedded with the psp-1000k (jap)

so, this makes me think that we "PSP-1000K" users will have to wait few more weeks/months before the "precious" new firmware to be realeased.

The downside of automatic firmware upgrades, is that if we can find a weakness that allows us to do homebrew (e.g., the Independence Day exploit on the PS2), it will be pretty easy for Sony to close it up and distribute it to all the current PSPs that have been sold (as opposed to waiting until another production run, like they've had to do on the PS2). Wow, that was a long sentence.

Just my 2c

Well, its not really automatic currently. But yeah, you may want to get a 2nd launch-day psp and keep it virgin.

Even if you could find what you could confirm is a buffer overflow in the JPEG viewer, what could you do with it? Without knowing how to access the GPU, MS, or even the serial port, what good does it do?

The same question can be posed to those trying to find a way in through these firmware images. Where are you going to get the basic info you need to get something on the screen?

hmm... I swear something odd is going on.

Curious as to what could crash the PSP, I took that above-linked image into a hex editor and made some selective, subtle changes.

Now I can crash my PSP almost at will :\
The PSP will freeze, rendering all controls dead and in 3-5 secs will power down.

The three JPEGs are here: http://pdc.me.uk/psp/freeze/

It takes some time so I just now attempted to write down a sure way of reproducing it.
I powered up and opened a3.jpg by pressing Circle and then once the picture was on screen, I selected the 'Display' option via the Triangle menu.
It froze straight away!
Now I power back up, open a3.jpg, follow the same procedure and there are no problems whatsoever.

Basically, by
1. Opening the JPEG for viewing (pressing circle to open)
2. Accessing the Triangle menu and selecting 'zoom'
3. Accessing the Triangle menu and selecting 'display'
All in a seemingly random order, my PSP will certainly crash pretty quickly.

I appreciate this is an awful method and I can gain nothing from it.
I've had no problems whatsoever with any other JPEGs though.

Perhaps someone with a 1st gen Japanese PSP could have a go,
see if I just have a dodgy PSP! :\ *worries*

Confirmed on the Japanese model.

I took a break from WipeOut and tried your jpg. All I had to do was choose the 'display' icon from the menu when I had the picture selected. Everything froze, controls didn't respond and after a couple of seconds the unit powered off.

Weird.

Interesting - I wonder if the powering off is like a built-in "protection" thing in the case of buffer overflow exploit vectors? or just a quirk...

Probably a watchdog timer. If the watchdog doesn't get touched after a few seconds (ie. the OS is deadlocked) it probably forces a hard shutdown. Inelegant, but not so much so as a reset button.
