thank you Ibocan for your message. This crash maybe useful but the problem is that i do not know how to continue from now on!
This is the reason why i am asking help in this thread from people who are more experienced from me!

Before you crash the game, please do
Code: Select allbpset 0x088B5E54

Then please run your stuff and then type
Code: Select allhwprint
step
hwprint


But there is not much hope :/

i tried once but i got this message when i got into memory card to run the game.

Code: Select allhost0:/> bpset 0x088B5E54
host0:/> 0x088B5E54: 0x0000000D '....' - break      0x0



But after i tried again by reseting vsh and then write again bpset 0x088B5E54.
this time it did not crash on the menu but it crashed on the game as it was normally doing.
then i typed the rest of the commands you told me and here are the results i got.

To make "step" you should delete breakpoint.
#199825 by stavrosomo
Thu Nov 15, 2012 8:10 am
you mean that i should first write this before i run the game
Code: Select allbpset 0x088B5E54


then i should write "hwprint" after the crash happens
and then i should restart my psp and then do "step" and then again hwprint?

sorry i am asking fool questions

frostegater or anybody else, can you please help me continue? Tell me if there is somebody who can help as i am still waiting for so long for just a simple answer. If i knew what i am going to do then i was going to ask.

My instructions were not complete:

Before you crash the game, please do

Code: Select allbpset 0x088B5E54



Then please run your stuff and then type

Code: Select allbpdel 0x088B5E54
hwprint
step
hwprint


Again, your exploit is most likely not expoitable.

I told you to display registers with hwprint but it actually doesn't display the registers we need.

I don't remember what is the instruction to display gp registers...
