【模拟器代码问题】模拟器如何通过代码控制Rom的背景音乐

独孤残云 · 发表于 2009-11-2 22:45:57

求助：模拟器源码中通过哪段代码控制Rom背景音乐的播放？
PS：看过一些模拟器的源码，大概都分为APU、PPU、NES那样几个版块。请大侠告知是哪个模块。感激不尽~~

看了下VirtualNes的源码，是APU那部分，全称应该是Audio Process Unit

能否再详细一些呢？本人比较熟悉上层的编程思想，但对于NES的底层算法机制基本是彻头彻尾的外行。
楼上的大侠可否帮我准确定位一下，是哪个.cpp文件中的哪个函数，感激不尽~~
这里有相应的模拟器源码，就当送给大侠了~~

聲音部分(Audoi Process Unit = APU):
.\NES\APU.cpp
.\NES\APU.h

影像處理部份(Picture Processing Unit = PPU):
.\NES\PPU.cpp
.\NES\PPU.h

如果原碼用C跟ASM混搭也不錯

楼上是高手哈哈

可以的话，希望可以得到krizal团长大人或者哪位大侠的详细赐教，就是指Apu模块下这些函数的具体含义和作用。我对这些NES机制的算法很感兴趣。
感激不尽~~

这是我手中源码Apu.cpp的内容，敬请赐教：
（由于很多专用术语和算法机理都不明白，所以看不大懂……）

, b( @1 K$ H6 a, S# H% s可以的话，希望可以得到krizal团长大人或者哪位大侠的详细赐教，就是指Apu模块下这些函数的具体含义和作用。我对这些NES机制的算法很感兴趣。1 B; S/ Z3 Z/ k
感激不尽~~

恩我對模擬器不是很有研究，
雖然要了解源碼內容，可能不是很困難，
不過還是要花時間，個人目前蠻忙碌的。

給你一個朋友的MSN，你可以跟他討論看看，
他本身是程式設計師，也對FC模擬器很有興趣。

MSN我就PM到你的信箱了。

希望你能有所得。

哈不敢當，我只是個平凡人，

FC模拟器的部分有个人可以帮你忙
ZYH
QQ：414734306
Mail：zyh-01@126.com

他是ZYH Emulator这个模拟器的作者，只是他用的开发平台是VB，不过就6502的实现原理来说是一样的
