Problems with the emulator...

(v006 and most likely earlier - A Culliney)

* Certain programs (Computist's Nibbler, Sword of Kadash Master copy
for example) don't work with the emulator because of a problem with the disk
emulation.  The Nibbler for instance gets stuck in a tight loop:
	1: LDA $C08C,X
	2: BPL 1
It's a busy loop while the MSB is 1.  Someone needs to hack around with this
some more.  You can check it out by dropping into the debugger (F7) when the
Nibbler hangs.  BTW, other emulators have the same problem.

* scandir() freaks out when there's a bad symlink in a directory.
work around: remove bad symlinks from disks directory. (libc.5, maybe glibc?)

* lores graphics colors are always in color mode.  I'm too lazy to bother
fixing this one.  Same goes for dhires graphics.

* dhires graphics color artifacts are not emulated correctly.  This
is my current holy grail.  Although colors seem to be off in ApplePC,
all the subtle artifacts are emulated quite well.  If only the
source were available!...

* key handling is quite ugly, partially because the SVGAlib version reads
scancodes, and the X11 version tries to be compatible with this...  It all
should work on US keyboards at least...

* Hmmm, what to do about the backspace key in //e mode.  Most of the time, the
//e seems to want this to be BS (0x08 | 0x80) when you press the key, but I
have noticed that at several programs (e.g. Freewriter for ProDOS) that
expect DEL (0x7f | 0x80).  I can't figure out what's different.
The (maybe) good news is that running the same problem occurs while running
the programs under ApplePC.  At least it's not just me.  Could this be some
sort of undocumented softswitch setting?  HACKAROUND: the PC Insert key is
always DEL...
