See the sdk provide with the 4.01M33 firmware there is a sample to launch
a cso,iso,ps1 game from a shell program when the program end it comes back
to your shell.

Code:
#include <pspsdk.h>
#include <pspkernel.h>
#include <pspdebug.h>
#include <pspctrl.h>
#include <psploadexec_kernel.h>
#include <kubridge.h>
#include <systemctrl.h>
#include <systemctrl_se.h>

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

#include "rdriver.h"


PSP_MODULE_INFO("BootLoad Test", 0x200, 1, 0);
PSP_MAIN_THREAD_ATTR(PSP_THREAD_ATTR_USER);

   va_list list;
   char msg[256];   

   va_start(list, fmt);
   vsprintf(msg, fmt, list);
   va_end(list);
   printf(msg);

   sceKernelDelayThread(milisecs*1000);
   sceKernelExitGame();
   asm("break\n");
   while (1);
}

int WriteFile(char *file, void *buf, int size)
{

   SceUID fd = sceIoOpen(file, PSP_O_WRONLY | PSP_O_CREAT | PSP_O_TRUNC, 0777);

   if (fd < 0)
   {
      return fd;
   }
   int written = sceIoWrite(fd, buf, size);
   sceIoClose(fd);
   return written;
}

Try to reverse the irshell prx files. Thats if you cant find the way todo so. Its not that easy todo so, including on what you are trying todo.

Wasn't irshell a kernel mode program?
It supposedly runs in kernel memory, which I guess is why some larger 1.50 kernel mode programs caused it to crash.

Yes it run in kernel mode. Ill post a example later then on how to run programs in the back ground. Its not that hard unless you want it to switch back and forth without and changes to happen. You can also output a file with some data on what or where it should be at.

ok now i got it to load an eboot and come back too it but i was wondering using the bootload sample can some explain how it works like does the original game where the second game was launched stay in memory or exit and will it crash the psp if the original one was using alot of memory

also how can i restart the game and have it come back to it or shutdown the psp and have it come back to the game
