[解説] SPRX Projectについて

※面倒なのでまだしっかりとまとめてはいません。

新しくSPRX作る場合は
Visual C++ → SCE → PS3 → PS3 PPU Project
Project typeはPPU PRX project

++++++++++++++++++++++++++++++

Project立ち上げた後
ソリューションエクスプローラーからprx.cppを開く
エラーのどれでもいいので右クリックしてエラー元開く
そのエラーページ上部に以下コード貼り付け

#include <sys/sys_time.h>
#include <sys/syscall.h>
#include <sys/ppu_thread.h>
#include <string.h>
#include <sys/syscall.h>
#include <stdarg.h>
#include <stddef.h>
#include <sys/timer.h>

++++++++++++++++++++++++++++++

SYS_MODULE_INFOを追加し、以下コード貼り付け

void sleep(usecond_t time)
{
	sys_timer_usleep(time * 1000);
}

int console_write(const char * s)
{
	uint32_t len;
	system_call_4(403, 0, (uint64_t) s, 32, (uint64_t) &len);
	return_to_user_prog(int);
}

sys_ppu_thread_t id;
sys_ppu_thread_t create_thread(void (*entry)(uint64_t), int priority, size_t stacksize, const char* threadname)
{
	if(sys_ppu_thread_create(&id, entry, 0, priority , stacksize, 0, threadname) != CELL_OK)
	{
		console_write("Thread creation failed\n");
	}
	else
	{
		console_write("Thread created\n");
	}
    return id;
}

++++++++++++++++++++++++++++++

PS3_PPU_Project1_prx_entryを追加し、以下コード貼り付け

void thread_entry(uint64_t arg)
{

}
//This is where all your mods will begin ^_^

++++++++++++++++++++++++++++++

PS3_PPU_Project1_prx_entry内に以下コードを記述する

create_thread(thread_entry, 0x4AA, 0x6000, "Main_Thread");
return 0;

Writing the Memory//I'm not entirely sure if this is correct, but it should be.
1 byte - *(char*)0x0000000 = 0x01; //Yes this is literately how you write the memory in C++.
2 bytes - *(short*)0x00000000 = 0x01;
3 bytes - *(float*)0x00000000 = 0x01;
4 bytes - *(int*)0x00000000 = 0x01;
8 bytes - *(double*)0x00000000 = 0x01;

例

for (;;)//Since the code practically runs once you'll need to add a loop
{
      if (InGame())//Detects when it's InGame so it knows when to run and not every half a millisecond.
      {
           sleep(5000); //Sleeps for 5 seconds then executes your code below.
           *(char*)0x1786418 = 0x40; //Thanks to mango for the player speed offset, This sets your speed x2 so we'll know if it works or not ^_^
      }
