我猜我找到了PS模拟器pcsx-rearmed在树莓派中运行效率不佳的原因了

wonder1999

这和模拟器版本无关，根本是在系统的kernel上。有兴趣的同学可以自行查看 dev/shm/runcommand.log中这个模拟器的运行记录。
保证几乎如下:

有人看出问题了吗？

问题出在这段呗，系统内核的问题。警告:内存未被直接映射，损害模拟表现

wonder1999

没错。而且这是因为系统内核的原因造成，所以大家应该都是这样

ygm1335

这应该算是个比较严重的bug，希望新版本能够修正

wonder1999

强者便是如此-搞定!

刚刚搞定，下载编译用掉4个多小时
换来不残疾了，哈

模拟效果都流畅了？

求公布方法啊

ygm1335

太强了。。。求公布

wonder1999

等我做段时间测试。 。
