@steward 感谢司徒的研究，发现了一个大BUG，中断号偏移计算错误，现已修复，打补丁如下：

@steward 我只想跟司徒大佬学习一下！😃

@ubuntu

还有一个IM3的模式设置位😲

@whycan 已加

@heidan 可以了太感谢了

@bedrock 好的，谢谢

分類的部分 要看源代碼才會知道 有一些老玩家會知道 MIPS模擬器的意思是使用MIPS汇编做加速 專門跑在MIPS CPU上面的模擬器 例如:reGBA模擬器 是GBA模擬器(ARM晶片) 但是 reGBA是MIPS專用的模擬器。

有些源代碼會包含ARM MIPS X86，但是 不是每個模擬器都會有全部平台的支援，開源模擬器 的缺點是 幾乎沒有說明文件 所以搞起來 比較累，很多東西 都是要看源代碼才會知道是支援什麼平台，不過比較新的模擬器 RetroArch 是使用C/C++ 寫的 因此 很多CPU都可以跑，缺點是過於肥大，大致上是這樣的情況。
