[B2-devel] Basilisk II Eating CPU cycles

[Jimmy <roc...@gm...>]

Hello everyone. i'm not sure if this is the right place to post this message. Please correct me if it is or not; I've been looking around to see where i can and well decided to give this a shot...

I've been using the latest version of Basilisk that is a Universal Binary. It ran pretty good after a few hiccups for about an hour or so till i hit a snag and im not quite sure what it is thats causing this problem. The Basilisk GUI utility as i know is PowerPC only, but the emulator istelf is a Universal Binary, and i believe that may be a problem for my Mac mini not running it properly.

I have an Intel Mac 1.8ghz Core Duo 2006, with 2GBs Ram, and 80GB HD, running OS X 10.6.2 Leopard. I have an inkling this may be partially responsible for the crash, due to Snow Leopards grand remodeling under the hood.

Anyways, when I try to start it up now and run the emulator, the window pops up for a 2nd displaying a floppy, of course, because it cant find a startup disk. The Basilisk emulator itself quits, but the Basilisk GUI utility hangs and actually slows my Mac to a crawl, eating up about 95% of CPU time.

Any way you guys can figure this out? I'd look into it myself, but I'm no where near the programmer expert, I'm only trying to diagnose by intuition.

Thanks in advance,
Matt

P.S. Here's a crash log to help with the diagnosis:
