DreamGBA是基于Windows98和DirectX5的GameBoy
Advance模拟器，所有代码均由李可文独立编写。DreamGBA是共享软件，允许免费拷贝和下载。如果您喜欢DreamGBA，欢迎您向作者注册
模拟器作者不提供GBA的ROM映像和GBA的BIOS（运行商业ROM所需）！
性能设定：
DreamGBA1.1版以后将自动跳帧的速度由1.0的30FPS改为60FPS，因此对系统的要求也有较大提升。如果您使用自动跳帧时发现帧数严重不足，请打开1/2 Speed选项，基本上即可流畅运行了
使用60FPS大致需要PIII800左右的CPU（估计值）
使用30FPS需要PII350左右的CPU
如不开启声音需求要低一些
使用方法：
请使用现成的模拟器前端DreamGBA Loader(DGBACFG.EXE)
或者其他兼容DreamGBA的前端，如DreamGBAGUI等
系统需求：
- Pentium
II 450级别或更高的CPU
- Windows98或兼容操作系统（未在Windows
2000/Me上测试）
- DirectX5兼容的显示卡，声卡和输入设备
本版特点：
CPU:
- 100%ARM7TDMI
CPU ARM Mode指令模拟，去除了GBA未用的协处理器支持
- 100%ARM7TDMI
CPU Thumb Mode指令模拟
- 准确的CPU时钟模拟
