yes, i just had to reassigned it to read/write privileges...

Does anyone know why sceIoOpen() with PSP_O_WRONLY flag doesnt work in flash0 ? I tried sceIoOpen("flash0:/test.txt",PSP_O_TRUNC | PSP_O_CREAT | PSP_O_WRONLY, 0777); But test.txt is only created if i open it in ms0: sceIoOpen("ms0:/test.txt"...

Do i have to load the vertex i want do display in user mode ? How do i do that?

Well, i am trying to draw a polygon in the XMB, using GU. So i am using part of the code of MDL, with list in user memory... But when i initialize the psp, it crashes. Here is the source code: http://codepad.org/PHcBqWKz Edit: I guess the problem is in allocating list in user memory. I did this, but...

I will just had to add this !(pad.Buttons & ...) to all the buttons. Btw, why isnt this working: int pad_ = 0x100000; if(pad.Buttons & pad_) {...} The inside of the brackets isnt being processed. I know this uses a bit mask, but they say Buttons is unsigned int. So the problem here could be ...

It doesnt work jojoris
EDIT: Solved. I just had to do:
if(pad.Buttons & PSP_CTRL_RTRIGGER && !(pad.Buttons & PSP_CTRL_SQUARE)) {...}

and this would only be processed if the user didnt press square..

but the problem is that if i only put:
if(square pressed) {...}

and if im pressing square and say triangle the code inside the brackets of the if statement is processed anyway and im pressing triangle too...

Is there a way of saying:
If(square is pressed and the others buttons are not being pressed) then...
?

Help

Well i just it could be done, but seems impossible. I tried GU, but can't get my image displayed, could you help? The screen just go blank and nothing happens... #include <malloc.h> #include <pspkernel.h> #include <pspdisplay.h> #include <pspdebug.h> #include <stdio.h> #include <stdlib.h> #include <...

Can you use the oldButtons (or paddata_old) method to avoid the psp executing the thread faster ? I can use it, but in this case of hooking it isnt working. I tried to use this (but it crashes and shutdown): int vshReadButtons&#40;SceCtrlData *pad_data, int count&#41; &#123; int ret, int...

now i have a weird problem when activating usb. If i toggle usb with my prx and then turn it off, all goes well. But if i toggle the usb again, the xmb automatically starts a usb connection itself (usual usb connection) and gives internal error 80243101. I find out that the problem was activating th...

Is it possible to blit images to XMB with OSLib? I know that it is possible with GU, but it seems kind of hard to learn... So if you know something about it, please tell me

maybe, i´ll try it.. It works! Thanks iceman755 :D

Well i finally solved my problem. I was making a prx similar to the vsh menu. If you press select the vsh menu comes in the xmb. And if you press a specific key, the psp activates the usb mode. I discovered that if usb is toggled and the vsh menu is in the xmb, the psp will freeze when suspending, b...

Hey, im developing a plugin that can toggle usb. Its working well, i can detect the psp on pc, but the problem is when the psp goes in standby. If i dont activate the usb i dont have problems. But if i toggle usb and after a while the psp goes in standby, the psp freezes and then shutdown. My questi...

It works now xD Tks cory1492.

Take a look at some of the file browser examples and see how that works.

Where can i find them ?

Havent found however the function to shutdown the psp completely.
scePowerRequestStandby and sceSysconPowerStandby() just suspend the psp. Btw, how could i explore the prx in flash0, including searching for functions and that kind ? do i have to use a decompiler ?

Well, ive seen what moonlight said about FindProc(). So, we use FindProc() to get the address of the function scePower_0442D852 (which is not in pspsdk) and how the hell do we use that function with only the address? Help please EDIT: Well i accidentally found a source on google and it is working no...

I installed GIMP 2.6 and saved as raw image (ourImage.raw) But cannot open this format with gimp, shouldnt this be possible? Btw, how can i store the RAW image either on MS or embedded? Do i have to do something like that: int fd = sceIoOpen&#40;"ms0&#58;/font.raw", PSP_O_RDONLY, 0...

i found vshblitter, but cannot compile it in kernel mode if i used USE_KERNEL_LIBC = 1 USE_KERNEL_LIBS = 1 I tried without those and it compiled but the prx didnt work, so i will try the links you gave me.. EDIT: Tried the first one, but it is the same. I think the problem here is when i am loading ...

Any function that can reboot the psp? I tried sceSysconResetDevice(1,1), but that doesnt work... Anybody used a different one ?

Now im trying to blit images on XMB. Does anyone here have the sources of the vshblitter. I searched the net, but all links are corrupted... Ive heard about GU in XMB but, i dont know anything about GU

Solved again... I had to put 0x18 on createThread in module_start, instead of 0x30.

Well i forgot to add to game.txt. It works fine. But what function do you use to shut off psp? Does it completely shut off, or it just suspend ?

Solved, i was not putting the blit.c right away. Anyway, the path to the two files are psp/sdk/include Now i can´t display anything on xmb, although it is compiling well. Here is the code: #include <pspctrl.h> #include <pspdisplay.h> #include <stdio.h> #include <pspkernel.h> #include <psppower.h> #...

Solved, i was not putting the blit.c right away. Anyway, the path to the two files are psp/sdk/include

Where do i have to put the blit.h, blit.c so i can compile ?

Are you sure you want the PSP to power off with just one button (L shoulder) held?

No it was just an example. Btw, this prx inside games doesn't work. Yes, turning off the psp completely seems impossible, but im happy with scePowerRequestSuspend();

Solved !! I had to put this on my Makefile LDFLAGS += -mnno-crt0 -nostartfiles Which means i dont need the SDK initialization, since i defined a module_start and the SDK (src/startup/crt0.c and crt0_prx.c) defines the entry point and call your own main. The prx is working, now i will try shutdown th...
