I'm sorry, but as we don't know for sure yet, this is the only thing you'll get. Alot of things can be the cause of this. All I'm saying is that malloc isen't totally wrong, but it could very well be that he noticed the difference between 1.0 and 1.5 and just assumed that it runs code. (Sorry malloc, but I don't know you, and I don't trust you :))

What we know for sure is that the PSP dosen't crash as said in the previews post, and it dosen't freeze as brightness and dimm mode is working. Some other things has been tried, but we I haven't come up with any conclusions yet.

PinkPeach, could you compile one of the simple graphic samples
of the SDK like the one with the balloons, or the dragon (I know they
work ok). Because if there's any debug info, or access to files or to 1.5
specific calls in your elf, it will not work on 1.0. If you could do that and
upload the elf somewhere, those with 1.0 would be able to see that
it works ok :)

I hope PinkPeach will be able to upload a better sample, and that everybody
will be able to see it works ok.

But then, what to do next ?

We can't install 1.0 on a 1.5 because 1.0 is not available in an install file.
And we can't even install 1.5 on 1.5, if the sfo is changed to 1.6, and the
.pbp launched, there's a CRC error during installation, so even if we had
the psar of a 1.0 it wouldn't work...

I was wondering if somebody really installed the leaked firmware, and
had time (before the psp dies ??) to look at the firmware version in the
information menu of the psp ... This leaked firmware looks like it has
been encrypted with the correct keys, and so, **should** execute on
a 1.5, allowing the installation of a previous firmware... even if it is
buggy...? (the leaked firmware SFO is not configured as an update,
but as a program -> no UPDATE param in the SFO, so there is no need
to edit it to make it work on a 1.5 like we need to do with the update SFO
of the 1.5 firmware install (put 1.6 instead of 1.5), and so there shouldn't
be any CRC error during installation...)

I'm so close to install this leaked firmware on my psp (or on one at the
office), but as anybody else, I'm so afraid of killing the psp...

The leaked firmware is just dummy data, so I would not try to flash it with that. ooPo and gorim had their experience with that :-/

@malloc:
why don't _you_ just upload your "working" samples to some place instead of asking other people to do it? or even a small video of the balloon sample running on a retail PSP would be some kind of prove that you're not just full of hot air? (get it? balloon? hot air?)

I don't upload anything, because I'm trying to help, but I want to stay
100% legit ! I don't want to loose the game developper job I love to prove
something ;) It's too much risk... (There's Sony NDA I've signed, and
copyright issues here...) I will not give any information that would break
this NDA, or provide any copyrighted material.

That's why we need somebody who doesn't care about those issues to
provide the elf if he wants to...

But still, using only available public information, we can still do things ;)

Otherwise, yes I could provide the full SDK, the DOCS (I have them at
work, and use them every day), tell anyone how the PSP works internally,
how to use the APIs etc... I probably know well everything a PSP
developper can know about the machine, I know the APIs, I coded a
full 3D engine on it, optimized using the co-processors in assembly etc...
But if I do that, or only give 1% of the above, tomorrow I'll loose my
job, I'll have Sony lawyers after me, and this whole PSP Homebrew
developpement thing would probably be closed by Sony !

We don't want that !

All we want is to find a legit way to develop homebrew programs on
this cool machine :)

heh, oh well... looks like it does work... you should have pointed out that it HAS to be the ELF and not the PRX...

Sony didnt give anymore info than what can be seen on public slides, ie no register/opcode listings etc, no code examples, and why would they show stuff like that on a seminar ?

Bugging malloc for elf's done using tools under NDA will solve nothing, case closed.

I think the games speaks for themselves in that area.
I guess you are easily impressed then.

Confirmed as working ? We dont have any proof still. I still wait the day at least a picture to see a simple demo running on a PSP 1.0 kinda.

what does the texture.bin do?
we can convert it with BinToElf....
(just an idea)...

Disassmbled the DATA.PSP in posted EBOOT and tried changing a value passed to sceGuColor(0xffffffff) to something else was assuming this set the bckgrnd color(Could be wrong). Still nothing still get black screen.

cyod, don't expect anyone to post an ELF, compiled with the SDK, public. It won't happen, so stop asking for proof/elf/whatever.

I agree with cyod on that part, if you post something you should at least give proof that it work. There is so many useless hoax its getting pathetic.
IE: Post if it work or dont post at all. See it another way, this thread doesnt bring developpers anything usefull for personnal howebrew coding... (at least for now). Its only 2 persons bragging how they got an SDK and dont give anything. Of course this is interessing, if this not another hoax (like the usual).

the information gives insight of the design of the system, and you'll need to know it, or wait for someone else to do the development for you.

My PSP 1.0 ready to test. Someone give a SDK compiled elf. : / Maybe Malloc show take some video/pics to show us it work : )

I've deleted the links to the software as it was found to have been built with the official toolchain. A bit late, I know... but better late than never.

In the future, please refrain from requesting or providing these files here. What you do outside of these forums is something I can't control, but when you're here please try to obey the rules.

Thanks!
