Help for create a prx

[jakbest]

Hi, I'm jacopo I'm new in this forum and I am an italian.
Now I study the MIPS r4000 for decompiling prx for create my cfw PSL (if there is another method for create a cfw, can u explain it to me?) I want to create an xmb in game with a vlf i have some images of my project:



and now i would like an advice to how can i create it? with the decompiling of impose prx or with a plugin? now for the 2nd option i don't know how to create a plugin which start with the press of home button and stop with home. Can i replace the "Setup callbacks"? Thanks for all answer there are very important for me!

P.S.: possible no abbrevation, thanks.

Use vlf lib. it creates the Vsh Look and Feel.

You want to create CFW?
Do actually know what CFW means since there are only a few people in the world who are able to create a CFW?

You have to use kernel mode if you want to capture the home button.


PS. please use correct english... it's kinda hard to understand.

If you want to make a CFW, look into dark alex's 1.50 cfw Proof of Concept. It's the basics.

Maybe Ahman can help you with loading your modules into the upper 32MiB of the Slim so you don't eat into any unallocated free space in the lower 32MiB, like he's done in IRShell when multitasking.

Getting the Sony XMB modules to load this way might be too difficult. If you code the interface and functions your self then it shouldn't be very hard. Just unregister the exit handler and detect the home button.

You should also check documentation about ELF format.
