[Coco] 6309 microprocessor project: 11-05-2003

[John Collyer]

Thanks Fedor, that is exactly my intent.  I'd like to follow Jeff's emulator
as much as possible because I think it works really good.  Some things in it
will have to change to make it work in win32 though, and I plan on using
directX graphics.  I like to model that part after the nesterJ emulator.
One example of change is how the 6309 Instruction Set Interpreter had to
change for 32 bit flat mode, but kept to the MSDOS version whenever
possible.  For example because there is no size constrictions in 32 bit flat
assembly (no segment registers to worry about) I was able to completely
macrotize the 6309 Instruction Set Interpreter, and it now only has 5 call
instructions and everything else is inline.  This will greatly speed things
up!

John, please do continue with your work on this! I believe there is a
genuine need for a exclusively CoCo emulator that both brings together all
that is now done by different other emulators and supports a whole bunch of
new extras too!

I mean, I like MESS, but the problem is that it does not help you much in
e.g. transferring files back and forth to the PC-environment. Then it is
going back down to Jeff's original DSKINI.EXE and RETRIEVE.EXE. But these
only work when you can get into true MS-DOS mode, which you cannot with
modern versions of Windows... And it would be neat to work with the 6309
instruction set without having to open the guts of your precious (real)
CoCo3 and doing all kinds of scary things to it.

If you can make an updated, user-friendly version of Jeff's emulator that
solves a lot of these problems than I think many people would be very
grateful!

Cheers,
Fedor
