Basilisk II is an Open Source 68k Macintosh emulator. That is, it enables you to run 68k MacOS software on you computer, even if you are using a different operating system. However, you still need a copy of MacOS and a Macintosh ROM image to use Basilisk II. ttyqb:makoto@u 22:35:45/021213(...emulators/BasiliskII)>

でも make すると次のようになってしまう。何かなぁ。

Configuration done. Now type "make" (or "gmake").

もしかして NetBSD/mac68k 等なら

Running m68k code natively ....... : no

native で走る ?
