Hi,

I'm trying to load some POPs from a hombrew without success. I keep getting 8002014E error...

This is the code which im using.

main.c:
Code:
#include <stdio.h>
#include "systemctrl.h"

PSP_MODULE_INFO("usbpops", 0x1000, 1, 1);


int test_thread(SceSize args, void *argp)
{
   char file[256];

   strcpy(file, "ms0:/psp/game/sles01760/eboot.pbp");

   struct SceKernelLoadExecVSHParam param;

   memset(&param, 0, sizeof(param));

   param.key = "game";
   param.size = sizeof(param);
   param.args = strlen(file)+1;
   param.argp = file;

   sctrlKernelLoadExecVSHMs4(file, &param);
   //sctrlKernelLoadExecVSHMs4(file, NULL);

   sceKernelExitDeleteThread(0);

   return 0;
}

int module_start(SceSize args, void *argp)
{

   int thid = sceKernelCreateThread("loadExecVSHMs4Thread", test_thread, 14, 0x3000, 0, NULL);
   if(thid >= 0) sceKernelStartThread(thid, args, argp);

   sceKernelExitDeleteThread(0);

   return 0;
}


Makefile:
Code:
TARGET = usbpops
OBJS = main.o

# Define to build this as a prx (instead of a static elf)
#PRX_EXPORTS=exports.exp
BUILD_PRX=1
#PSP_FW_VERSION = 371
# Define the name of our custom exports (minus the .exp extension)

USE_KERNEL_LIBC=1
USE_KERNEL_LIBS=1

CFLAGS = -Os -G0 -Wall -fno-strict-aliasing -fno-builtin-printf
CXXFLAGS = $(CFLAGS) -fno-exceptions -fno-rtti
ASFLAGS = $(CFLAGS)

INCDIR = include
LIBDIR = lib
LDFLAGS = -mno-crt0 -nostartfiles
LIBS = -lpspsystemctrl_kernel

EXTRA_TARGETS = EBOOT.PBP
PSP_EBOOT_TITLE = usbpops

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


I don't know what I'm doing wrong, as the sctrlKernelLoadExecVSHMs4 isn't documented anywhere...

Using that code, if i call sctrlKernelLoadExecVSHMs2() to load a standard homebrew works fine, but not for a PSX EBOOT using sctrlKernelLoadExecVSHMs4().

Any hints?

After looking strings from some others people .prx to load pops i found they use the key "pops" for SceKernelLoadExecVSHParam structure.

Also there is a strange behavior white the filename string... the "eboot.pbp" string must be uppercase, otherwise it wont load...

Here is a working code

Code:

#include <stdio.h>
#include "systemctrl.h"

PSP_MODULE_INFO("usbpops", 0x1000, 1, 1);


int test_thread(SceSize args, void *argp)
{
   char file[256];

   strcpy(file, "ms0:/psp/game/sles01760/EBOOT.PBP");

   struct SceKernelLoadExecVSHParam param;

   memset(&param, 0, sizeof(param));

   param.key = "pops";
   param.size = sizeof(param);
   param.args = strlen(file)+1;
   param.argp = file;

   sctrlKernelLoadExecVSHMs4(file, &param);
   //sctrlKernelLoadExecVSHMs4(file, NULL);

   sceKernelExitDeleteThread(0);

   return 0;
}

int module_start(SceSize args, void *argp)
{

   int thid = sceKernelCreateThread("loadExecVSHMs4Thread", test_thread, 14, 0x3000, 0, NULL);
   if(thid >= 0) sceKernelStartThread(thid, args, argp);

   sceKernelExitDeleteThread(0);

   return 0;
}

Yeah, I'm pretty sure discussion of this sort of thing isn't exactly kosher here.
