With psp-packer from 4.01M33-2 SDK I get ~PSP file and file works fine! :)
Thx for help.

First of all it SHOULD be a .prx file NOT .elf. You must build with BUILD_PRX = 1 Yes, I did that with prx. On Windows, just drag your .prx on top of psp-packer.exe. The file will be compressed. It will have ~PSP as first 4 bytes The file now is smaller, but the first 4 bytes is still ".elf&qu...

Well I tryed to use it. It hidded all string variables but I searched for "~PSP" and didnt find it, so I guess it is only gzipping prx. And a sad thing that when I added to psp it didnt work, I get error that prx is unsupported type.

Sry for not very clear question... I mean I want to compress and encode prx like some others do. Now when I open my prx in hex editor I see ".Elf" at the bigining and all strings are editable... so I want to make it to "~PSP". I think its the same as firmwares prx'es are comprese...

I have elf file and I need to compress it to prx. how to do that?

Could you tell me more about reversing functions? I need something to hook to.

Hi, I would like to know how to analize vsh_modele functions? is it possible?
Here is vsh_main functions, but how to know what do they do and what variable do they need?
I would like to cooperate with vsh_module :D

I think the main volume is saved in the registry. Try searching in it.

I have one more question, when I change cpu frequency in XMB and go to videos cpu frequency changes back to 222Mhz. why?

Torch wrote:Pretty sure there is NO way to change the UMD mode or anything while the game is running.

I am making a prx plugin on XMB it should make the same as VSH menu... So is there any other ideas how to make "UMD ISO mode" and "USB device" changes work without reboot like in VSH menu?

Original VSHmenu plugin can change settings without restart. It changes cpu, usb driver and umd iso mode. How it do that?

I already using this function but it just write new settings to settings file I quess. It doesnt apply them.

Well VSHmenu writes new settings to config file and somehow applies it (VSH cpu, game cpu, umd iso mode, usb drive). Maybe there is a function?...

It works, now I can change recovery settings, but there is a small problem, when I change them they changes only after restart.
Is there a way to apply the settings without restart?

Thx, I found that file and spotted cpu frequency :)
I wander is there any danger to work with that file? can I brick psp or something?

How to get/set recovery menu settings to/from my program? where are the settings saved?
I would like to get cpu frequency for XMB and games and be able to change it...

Thx very much, this sample helped me.

I am trying to export function from kernel and import it on user mode prx, but make that work. It doesnt work when I am trying to export function from user and import it on kernel mode too. So is it possible to do that at all? I guess it is users and kernels memory issues, because when I export from...

Here is what I was working for all the time. It is PSPconsole v1.2. Usefull: Quickly see battery info. Delete, cut, copy, rename, view properties of file/folder, set them hidden/read-only. View text files. Play C snake, Tetris. Sort your games and homebreews. Use calculator. View calendar. And all t...

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

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?

sceKernelStopUnloadSelfModule() return the same :(

Yes, I am using 0x1000 in my PSP_MODULE_INFO. I have noticed that if I use USE_KERNEL_LIBC=1 USE_KERNEL_LIBS=1 in my makefile, module stops and unloads, but I dont want to use these, because I need lots of functions from math.h and to convert float to string function for this module :( Is there any ...

I am trying to stop kernel module it self and unload itself by using sceKernelSelfStopUnloadModule but i get error 0x80020136. I found that it means "SCE_KERNEL_ERROR_CAN_NOT_STOP". How to solve this error?

How to set, unset file hidden, read-only options?

solved :P

Thx Torch, I am trying to use sceKernelAllocPartition function :) I allocated memory for some chars..... but how to allocate memory for double array? //short int ar[60][34]; SceUID mem = sceKernelAllocPartitionMemory(2, "mem", 0, sizeof(short...

what if I leave my prx as is in kernel mode and just add PSP_HEAP_SIZE_KB(1024); ? will there be more memory bugs with this?

I guess user mode would be better for me because my prx is usable in XMB menu, not in games. But how to disable XMB buttons from user mode? maybe there is a way to start prx in kernel mode and after patchsyscall make it user mode something like that?

well everything seems to work better now, I just have problems with float and double type variables, they are = 0; but when I try to print them I get letter "f". why? :( before adding thouse two lines in make file these variables worked fine.... P.S. what are pros and cons of making a prx ...

This is what I get after psp-size: text data bss dec hex filename 109768 2360 28688 140816 22610 PSPconsole.prx I guess it is realy big numbers for prx, yes? well I dont use USE_KERNEL_LIBC=1 and USE_KERNEL_LIBS=1 in my make file because then such functions as time(), clock() and some other are unde...
