I am an old and sentimental mac os 7-8-9 fan.
For mac os 7-8 I use BasiliskII and that works well.
For mac os 9 I have been using Sheepshaver (qemu works too but sooo sloooow)
The problem is that Sheepshaver will not build on Arch(and derivs). I have looked for solutions but the only thing I can find is that someone made a successful build may 14.
Anyone with a hint?
