Emulators for Mac OS 8.6

Hi all:

I've been searching for a while for a NES and SNES emulator for OS 8.6 but none of the ones I try work:

Snes9x says it can't find DrawSprocketLib--DSpFindBestContextOnDisplayID, but I installed the Apple game sprockets. I don't know much about OS 8.6 so maybe I'm missing something.

Graybox: I try to load a ROM but the Open dialog box doesn't even come up...?

Can someone please help me out?

Any luck using this one below? (as I'm not Mac user)

Alternate link :
NES : Nestopia
SNES : SNES9X

Thanks for the links, but both of those require OS X. I am running OS 8.6, which is not compatible with OS X.

Did you try them though? (As I looked the posts below in that pages, that there are some users using older version of Mac)

As I expected, they don't work. I tried.

You can find a lot of Mac emulator here, but OS X it's needed. More here, and some don't need OS X
