Instead of the platform dependent code calling a routine to emulate one tick (sixtieth of a second) whenever appropriate, the main loop of the program is now in platform independent code, which periodically calls platform dependent code to check for events. A visible consequence of this is that the emulation will now stop running in certain circumstances when it used to continue running, such as during the open disk image dialog. The exact situations this happens varies for each platform. </p> <p> * To minimize glitches in sound output when emulation starts, stops, or just isn't running fast enough, the sound call back functions in the various Macintosh versions and the SDL version will now try to play an appropriate transition in each of these circumstances. </p> <p> * In the Cocoa port, when the platform dependent code checks for events, rather than using a time out value, it turns out there is a bit less overhead to check for events, sleep, and then check for events again. This allows matching the performance of the Carbon version, making the Cocoa version more ready for prime time. (Apple has declared Carbon very, very deprecated.) </p> <p> The same fix actually also applies to Carbon. Mini vMac used to use a standard Carbon event loop with a complicated system of timer events only because a manual event loop didn't get quite as good performance. With this change, all ports can use the same platform independent event loop, as described above. </p> <p> <a name="bugs"> <b> Bug fixes in default compile </b> </a> </p> <!-- <p> * None Yet. </p> --> <p> * The Virtual-Key Codes of Microsoft Windows, that are independent of differences in keyboard hardware, turn out not to be independent of the choice of Keyboard Layout. Changing the Keyboard Layout to something other than "US" may scramble the Virtual-Key Codes, strangely enough. Mini vMac will now check the current Keyboard Layout, and attempt to unscramble the codes, so that the Keyboard Layout chosen in Macintosh o
