PSP2000 Hello world

1. PSP2000 3.60 M33
2. devkitProUpdater-1.4.7.exe 安装到 D:\devkitPro
3. 开始 --> 所有程序 --> devkitPro --> MSys
4. cd /d
5. mkdir /d/PSP
6. cd /d/PSP
7. mkdir HelloPSP2K
8. cd HelloPSP2K
9. vi main.c

/// Hello PSP - My First App for the PSP

#include <pspkernel.h>
#include <pspdebug.h>

PSP_MODULE_INFO("Hello PSP", 0, 1, 0);
PSP_HEAP_SIZE_KB(20480);

// Exit callback
int exit_callback(int arg1, int arg2, void *common)
{
sceKernelExitGame();
return 0;
}

// Callback thread
int CallbackThread(SceSize args, void *argp)
{
int cbid;

cbid = sceKernelCreateCallback("Exit Callback", exit_callback, NULL);
sceKernelRegisterExitCallback(cbid);

sceKernelSleepThreadCB();

return 0;
}

// Sets up the callback thread and returns its thread id
int SetupCallbacks(void)
{
int thid = 0;

thid = sceKernelCreateThread("update_thread", CallbackThread, 0x11, 0xFA0, 0, 0);
if(thid >= 0)
{
sceKernelStartThread(thid, 0, 0);
}

return thid;
}

int main()
{
pspDebugScreenInit();
SetupCallbacks();

pspDebugScreenPrintf("Hello PSP");

sceKernelSleepThread();
return 0;
}

10 vi Makefile

TARGET = hello
OBJS = main.o

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

EXTRA_TARGETS = EBOOT.PBP
PSP_EBOOT_TITLE = Hello PSP

PSPSDK=$(shell psp-config --pspsdk-path)

BUILD_PRX=1
PSP_FW_VERSION=371
include $(PSPSDK)/lib/build.mak

11. export PATH=$PATH:/d/devkitPro/devkitPSP/bin
12. make
13. 查看生成的文件
$ ls
EBOOT.PBP Makefile PARAM.SFO hello.elf hello.prx main.c main.o
14. 连接PSP2000到电脑，假设 盘符为 F盘
15. 将文件复制到PSP2000上（F:\PSP\GAME），创建目录 F:\PSP\GAME\hello
将文件：EBOOT.PBP hello.elf hello.prx PARAM.SFO 复制到目录 F:\PSP\GAME\hello
16. 断开USB连接
17. 在游戏下将可以看到 Hello PSP这个新的目录项
18. 运行 Hello PSP , 在屏幕左上角将出现 Hello PSP 字样
至此，终于将PSP2000的开发和运行环境搭建完毕。
