Posted: Wed Sep 20, 2006 1:04 am Post subject: HowTo add Kernel access under FW2.50/2.60 VSH (eLoader-TIFF)

sample
Download-Link : http://rapidshare.de/files/33680044/25_26_VSH_KA.zip.html

main.c
add line extern void kernel_ent(u32 Temp);
and write Kernel access in a function
use kernel_ent((u32) &your_function) to call it

Code:

// -------------------------------------------
// Kernel access under FW2.50/2.60 VSH
// use Noobz's eLoader(TIFF) 0.9.8
// -------------------------------------------
// Game mode Kernel access by hitchhikr / Neural.
// VSH mode Kernel access by moonlight
// Mod. by 0okm
// -------------------------------------------

// -------------------------------------------
// Include
#include <pspkernel.h>
#include <pspdisplay.h>
#include <pspdebug.h>
#include <pspctrl.h>

#include <stdlib.h>
#include <stdio.h>
#include <string.h>

PSP_MODULE_INFO("25_26_VSH_KA", 0, 1, 1);
PSP_MAIN_THREAD_ATTR(THREAD_ATTR_USER);

#define printf pspDebugScreenPrintf

extern void kernel_ent(u32 Temp);

void Dump_kmem(void)
{
int handle;
handle = sceIoOpen("ms0:/0x88000000-kmem.BIN", PSP_O_WRONLY | PSP_O_CREAT | PSP_O_TRUNC, 0777);
sceIoWrite(handle, (void*) 0x88000000 , 0x400000);
sceIoClose(handle);
}

void Dump_klib(void)
{
int handle;
handle = sceIoOpen("ms0:/0x88800000-klib.BIN", PSP_O_WRONLY | PSP_O_CREAT | PSP_O_TRUNC, 0777);
sceIoWrite(handle, (void*) 0x88800000 , 0x100000);
sceIoClose(handle);
}

void Dump_boot(void)
{
int handle;
handle = sceIoOpen("ms0:/0xBFC00000-boot.BIN", PSP_O_WRONLY | PSP_O_CREAT | PSP_O_TRUNC, 0777);
sceIoWrite(handle, (void*) 0xBFC00000 , 0x100000);
sceIoClose(handle);
}

int main(int argc, char* argv[])
{
pspDebugScreenInit();
printf("\n");
printf(" Kernel access under FW2.50/2.60 VSH\n");
printf(" use Noobz's eLoader(TIFF) 0.9.8\n\n");

printf(" Game mode Kernel access by hitchhikr / Neural.\n");
printf(" VSH mode Kernel access by moonlight\n");
printf(" Mod. by 0okm\n\n");

printf(" FW ver is 0x%.8X\n\n", sceKernelDevkitVersion());

SceCtrlData pad;
sceCtrlSetSamplingCycle(0);
sceCtrlSetSamplingMode(0);
u32 oldButtons = 0;

printf(" Pass [TRIANGLE] to Kernel mem. Dump\n");
printf(" Pass [SQUARE] to Kernel lib. Dump\n");
printf(" Pass [CIRCLE] to Kernel boot Dump\n");
printf(" Pass [CROSS] to EXIT\n\n");
while (1)
{
   sceCtrlReadBufferPositive(&pad, 1);
   if (oldButtons != pad.Buttons)
   {
      oldButtons = pad.Buttons;
      if (pad.Buttons & PSP_CTRL_TRIANGLE)
      {
         kernel_ent((u32) &Dump_kmem);

         pspDebugScreenSetTextColor(0xFFFF0000);
         printf(" Kernel mem. Dump Finish\n");
      }
      if (pad.Buttons & PSP_CTRL_SQUARE)
      {
         kernel_ent((u32) &Dump_klib);

         pspDebugScreenSetTextColor(0xFF00FF00);
         printf(" Kernel lib. Dump Finish\n");
      }
      if (pad.Buttons & PSP_CTRL_CIRCLE)
      {
         kernel_ent((u32) &Dump_boot);

         pspDebugScreenSetTextColor(0xFF0000FF);
         printf(" Kernel boot Dump Finish\n");
      }
      if (pad.Buttons & PSP_CTRL_CROSS)
      {
         sceKernelExitGame();
      }
      sceDisplayWaitVblankStart();
   }
}

return(0);
}

Makefile
in line OBJS add kernel_ex.o
in line LIBS add -lpspvshbridge

Code:

TARGET = 25_26_VSH_KA
OBJS = main.o kernel_ex.o

INCDIR =
CFLAGS = -G0 -Wall -O2
CXXFLAGS = $(CFLAGS) -fno-exceptions -fno-rtti
ASFLAGS = $(CFLAGS)

LIBDIR =
LDFLAGS =
LIBS= -lpspvshbridge

EXTRA_TARGETS = EBOOT.PBP
PSP_EBOOT_TITLE = FW2.50/2.60 VSH Kernel access
PSP_EBOOT_ICON = ICON0.PNG

PSPSDK=$(shell psp-config --pspsdk-path)
include $(PSPSDK)/lib/build.mak
