      @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:

      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。
