OSK in XMB prx plugin

hotter · Post by **hotter** » Thu Feb 26, 2009 7:20 pm

I tried to use OSK (on screen keyboard) in my XMB prx but it crashes. So is it possible at all to use osk in XMB prx plugin? if so, what could I be doing wrong? prx sould be in user mode or kernel?

I don't think a kernel prx can use the OSK. And in user mode there is no memory to load the OSK in XMB on the Phat, aside from various other complications due to the VSH rendering the menu already.

And how about using the same OSK like XMB uses to change Nickname? I guess it is already loaded... Is it possible?

It'll be way to complex to hijack any already loaded ones.

I don't know if i have well understood, but Torch, do you have any suggestion on how to find already loaded OSKs?

Nah thats way beyond me. You'll have to ask someone with vast reverse engineering experience.

Kernel mode should have 100% access to any type of function. I'm not saying it does, but it should.

Since the SCE OSK can load on the xmb, you might have to have enough memory to load it. Or it may crash. Ill take a closer look at the xmb memory tomorrow. I might have to check the ipl too.

You can call the functions from kernel, but the the GU stuff that it uses needs allocation in user memory.

Right. You also better dump the pre-IPL and check that incase they've sabotaged the OSK from being used by homebrew at boot time.
