In the last four years - yes, you're the first.

BTW, I still believe that the F1=Help makes sense because most Joe Average Users will press the F1 when launch it for the first time - even without reading documentation - just due to common behaviour of other (DOS/Win) applications.

done in SDL port (when Petr will update CVS)

I might do that, along with the hopefully now 100% operation 65816 core.
I've added it in the same way the memory.[ch] files were done.  I have the
original 6502 code as cpu-02.[ch] and the new 65816 code as cpu-816.[ch],
816*.[ch], and opcodes.h.  The 65816 code is essentially a direct pull from
the XGS/32 source, so I need to make sure I edit each file and put some
credits in there for the original author.  I've considered merging the files
into just cpu-816.[ch], but that isn't entirely possible the way opcodes.h
is used.  Someone might want to take this 65816 module and change create a
6502 equivilent.  Basically, every opcode (in all 5 CPU modes of the 65816)
has it's own function.  An array of the functions is created and the main
CPU loop just calls the appropriate index (based on the offset calculated by
the CPU mode).

Somehow I doubt that I'm the first to come up with the key mapping ideas I
have.  But it's nice to know it's "in the works" so to speak.

if you got bored by patching each new version of Atari800 for your
changes then clean them up and submit for inclusion in the main source 
tree.

BTW, I just found this in the original David's USAGE:

"Note: The function keys will eventually be changed to a more logical
order."

So perhaps this is the call for reassigning the keys as you suggested?

I'm assuming it had to do mainly with speed.  Rendering all of that would
take nearly twice the overhead in the program, plus it would only benefit a
select few that really wanted it.  It could be done as a compile-time
option, I suppose.

Of the 228 color clocks per scanline, the narrow playfield uses 128, normal
uses 160, and wide uses 192.  The remaining clocks are the border.  The
default display list, if I recall, starts with 24 blank scanlines (hence the
3 112's/0x70's at the beginning).  So, technically, a 384x262 (or 384x312 on
PAL) mode should be physically possible on the Atari hardware.  Not that
anything uses that, but if we're going to emulate the system, why not
emulate it all the way.  Right?

What exactly is maximum possible screen size of Atari XL/XE ?  I remember

[Atari800-users] 65816 module progress and more

[Nathan H. <ma...@ma...>]

As a few may be aware, I have been working on porting the 65816 CPU
emulation from the XGS/32 (Apple IIgs emulator) project.  I seem to have it
done, but I have discovered a flaw with my plan.  The current Atari800
project relies upon unused opcode values in order to use native C code to
emulate certain functions of the Atari system.  There are no unused opcode
values in the 65816 CPU, so all of those "escape" functions have to be
disabled.  There is the possibility of somehow tying these "escape"
functions to the COP instruction, but I have not looked into anything like
that.  Instead, seeing as how the only "escape" functions that are being
added are to enhance screen/keyboard/disk I/O, handle printing, and
introduce an H: device (that doesn't work with any version of SpartaDOS that
I've tried), I was thinking of adding a virtual PBI device (similar to the
MIO or BlackBox).  Being a virtual PBI device, activating the appropriate
device bit could  trigger "intercept" routines that perform the appropriate
functions in native C.  Of course, a dummy PBI ROM would be coded to allow
software to "see" it and respond accordingly.  For that matter, the
MIO/BlackBox ROM image could be used for this function.  Instead of
partitions on a real hard drive, individual ATR files could be used to
represent each partition.

Also, I've noticed that the current antic.c code is not written to display
the entire 228 color clock scanline as the ANTIC/GTIA actually create it.
Is there any reason why we clip the left and right sides?  It'd be cool, but
not required I guess, if the entire display (including the full borders) was
available for those of us capable of and/or willing to enable a large enough
display.  512x384 would cover it as 228 color clocks expands out to 456
"pixels", and NTSC/PAL goes to 262/312 scanlines.  Anyone else interested in
the full display?
