It can be extracted from the memento distribution. Since it runs from memory card, it uses magic gate encryption. Last time I checked the memento files it was based of scph-30003/4 V3 dvd player code, with memento patching in their code. So you should think twice before posting "firmware dumps&...

Unfortunately I don't have a 40G one yet.

But I've noticed that Assasin Creed comes with 1.94 fw, that was not available for download.

just an update :)

there's nothing special about this :P modchips is not the only way to run code on ps2. now that the ps2 is getting older there are rather many ways to do that. 1. modchips 2. exploits 3. pressed discs 4. linux (hum, did i miss another one?) 4. dvdplayer updates and other utility discs are blackliste...

yeah, it's a ps2 homebrew. you run it like you run on ps2. one (several?) of the ways works also on ps3 :)
don't know about ps1 homebrew

i have a bios dumper for ps2 that i ran on ps3 :)
no decryption.

I'm quite sure that the IOP was emulated in jap and us consoles. you can see the "beta" emulator in ps2 bioses (scph75k and 77k), under the name of DECKARD probably they went one more step and removed the EE as well. i think the next firmware updates will have different ps2 kernels, for ja...

When you run a PS2 disc on PS3, sometimes it exits with an error code. Here there are some: 80028F17 - booterror 80028F18 - unsupported disc; eg. Utility discs, BB discs, IQ Remix game etc. 80028F19 - fsck; the internal PS2 disk got corrupted and I guess that you can use HDD utility disc to fix it 8...

see http://www.jp.playstation.com/ps3/updat ... er131.html and http://www.jp.playstation.com/info/supp ... 2.html#hdd
i quote from translated text: "It cannot use PS3 built-in HDD as HDD of PS2"

On japanese site they say that you can install PS2 games to hdd.
They started that in 1.30 but didn't finish.

i seem to remember reading that these were mostly fixes for broken ps1/ps2 games. (along with security) the ps2 bios from ps3 is the same for 1.00 and 1.02 firmwares. it changed only in 1.10. haven't checked yet in 1.11 but i think is the same. and that is for ps2 games. i think the ps1 games (and ...

it's about 91 megs (95358584 bytes) realy. the rest is just padding

unfortunately, the kboot loader doesn't support very well sony ps2 keyboard :(

commenting out _fseeki64 is not a good idea; you'd rather replace it with a fseek64 variant. even fseek will do

We don't know how to REGENERATE (Aka Encrypt) PRX files. The "key" area you see at the start of the PRX is only part of a relatively complicated decryption process (it is merged in with several other "keys" stored in the PSP - and run through the decryption hardware) There are s...

what is in $22? who sets/uses it

some info for low-level devs:
http://ps2dev.ps2-scene.org/COP0_CONTROL.txt is the list of the COP0 Control registers and how they are used :)

the problem with loading network modules is that they are running in user mode. kernel application cannot link to user-mode modules afaik. if our app is running in user-mode it cannot load the modules from flash or ms. so there are 2 solutions: 1. another kernel mode patch added to pspsdk to allow a...

For those interested, PS3 SPU toolchain was released :)

And also a linux build (for ppc64) w/ sources.

It doesn't compile.

:) then get this: http://ps2dev.ps2-scene.org/pspdecrypt_wip.rar
it uses some of the above code (uses decrypt function, but links with kernel semaphore).

Very nice one, Nem!

The trouble comes due to a lack of knowledge of the internals of the psp threading system. Ideally gdb-stub would only work in exception mode and it would directly hook into the thread manager to switch thread contexts on the fly, but something like that will probably never happen :P maybe it would...

not realy related to the subject here are some flags for thread creation PSP_THREAD_ATTR_SCRATCH_SRAM = 0x00008000, PSP_THREAD_ATTR_NO_FILLSTACK = 0x00100000, PSP_THREAD_ATTR_CLEAR_STACK = 0x00200000, if someone will care to add them to the lib... With the exception of *_CLEAR_STACK, what do they d...

It's also worth mentioning that several pspsdk samples demonstrate a clean way to use pspKernelSetKernelPC. that will not save you from troubles when running in kernel mode. every time you create a new kernel thread you have to OR the entry with 0x80000000. and every time you are have a big switch ...
