What's New:
- Ignore WDM 0xfc,0xfd,0xff to avoid HOST.FST causing Code Red.
- Fix $C019 reading to match Deater's Midline demo
- Add false reads for RMW instruction, (dloc),y, abs,x, and abs,y modes. Only 8-bit false reads are done currently (this only affect 16-bit RMW, where I know of nothing using the false reads).
- Fix reported bug where long paths in the file selection screens didn't truncate the files so the endings could always be seen.
- Allow 140K .SDK images to be selected in the image file selection screen.
- Fix $C030 speaker toggle emulation to eliminate a 60-Hertz buzz caused by the code being organized around 60Hz screen refresh and not counting on the last toggle correctly in all cases. The $C030 speaker output ramps down to 0 after about 60msec to avoid the annoying "click" 4 seconds later when KEGS pauses sound output.
