Launch SonyOS from homebrew application!!!

placasoft · Post by **placasoft** » Sun Aug 21, 2005 8:26 am

I have started the psp dashboard from an homebrew application. As example it is possble to use our screenshot code in the background. The goal is to launch another firmware that way.
I want to load another firmware from the memory stick. But how I can change "flash0" to "ms0" ... any idea?
Could it work with "sceIoUnassign" and "sceIoAssign"?
Thanks, Team Emergency Exit (McZonk and me)

Yes, but not yet. I'll release it when it's finish ;)

EDIT:

is this ok?

Code: Select all

		sceIoUnassign&#40;"flash0"&#41;;
  sceIoAssign&#40;"flash0", "msstor0p1&#58;", "fatms0&#58;", 0, NULL, 0&#41;;

Maybe someone is interested :

This starts the Os again from flash!

I work with Vampire together, maybe we can make it that you can start 1.52 form MS ;)

very interesting, might have to check it out. Don't see too much use for it other than what your intentions are, though ;)

hmm very interesting indeed. If us 1.0 & 1.50 owners could launch 2.0 that way to use the new internet browser, it sure would be sweet.
One question though, i guess you can only start a firmware that's been decrypted right?
And since 2.0 uses an alternate encryption mode, it's not possible to launch it yet, am i right?
Great work neverthless!
Later,

hmm, i dont really get what this does. i know what you want to do with it. but this just seems to just restart the os. why not try making it launch firmware 1.0 so we can see if this really can work.

if that kid gets that psp emulator for computer running we can just run the 2.0 update on it right and then just get the new firmware off our computers

Want to reassign flash0 to ms0 ?
Will not work since on reboot the psp kernel will change it back to flash0.

Not the right way i think.

I think it is not a kernel loader but only a psp rebooter.

Am i wrong ?

a good way to check would be to change (in the firmware on your ms) the boot up video and see which one it uses

Hey,
it's don't reboot the system! It's starts all needable prx. Well at this time it's not possible to start the OS from MS cause the one prx remap all function new. We need to hijack this function! But I don't know who :/

Rather than only screenshot, when you restart the dashboard, it is possible to grab a video ? if yes, does these function still work in a game, to take video inside a game when we want and drop it in a MS ?
