Or is there a rom converter similar to UPD49ROM for the G+?
I admit, I may be retarded here. I tried using UPD49ROM to update the
emulator rom file, but it kept telling me the flash file was not in the
right format. It worked well enough to update my calculator so I'm
thinking this utility only works for the 49G but I may be wrong.
Thanks for the help in advance :)
Debug4x (www.Debug4x.com) has a special 49G+ ROM supplied by HP which
interacts with some unique code in EMU48+
to simulate many (but not all) parts of the 49G+. This special ROM is
updated when they have spare time. You must have this specially coded ROM
to do the emulation, the ROM must run on the special version of EMU48
(called with version names like EMU48 v1.38+).
There are no other emulators for the 49G+ or uploads of the ROM.

Installed it, works great :)

Well, much of the 49G+ ROM still consists of
the same RPL and the same Saturn ML as in the 49G,
with the lower-level ARM code spending most of its time
emulating the Saturn processor, hopefully so well
that except for a special "door" allowing Saturn<->ARM
interaction, you mostly can't tell the difference.
Certainly you would never be able to execute
an HPGCC/ARMtoolkit program on an emulator
which acted only at the Saturn level,
but it appears that somehow the feat of
segregating the Saturn level from the ARM level
is already done by the combination of the modified
Emu49+ application and the special Emu ROM file it uses.
Is it out of the question to be able to update an existing
older-version special Emu49+ ROM file, using the
Saturn portion of a new "real" calculator ROM version,
or could it be done in principle,
if not yet implemented in practice?

Well, I updated my old HP 49G with the emulator ROM of debug4x and it
works just fine, so now I have a 49G running ROM 2.01-1.
At least we finaly got a ROM update for the 49G ;- )

Which ROM?
How?
Did it really work?
Any caveats?

The keyboards are different. What happens with the CAT key for example?
Sticking to your question, this is the code for the CAT-Key (49G) or
the EVAL-Key (49G+):
::
TakeOver
IsApple_ (<- Checks the machine the software is running on )
NOTcase
FPTR 2 85 ( run 'Catalog' if 49G )
' ( run EVAL )
xEVAL ( if on )
DoKeyOb ( 49G+ )
;

P.S. And debug4x sure is a great piece of software, I wrote some nice
applications with it.

> The keyboards are different. What happens with the CAT key for example?
I'm not trying this ROM transfer myself at the moment,
but to give a related note, I use one common archive backup
for my 49G and 49G+, and through model-dependent
user key definition swaps in my STARTUP,
I have made them correspond exactly in keyboard function
(actually I had long ago swapped keys to end up on my 49G
with a key function layout almost like the 49G+ anyway).
Besides potential default key definition differences,
I wonder what else might be affected -- what dimensions
would be reported for screen grob size, are any
built-in functions trying to display the extra lines, etc.
Finally, what sort of test would distinguish for sure
which *physical* model (not just which type ROM image)
is in use, which has similar implications about screen size
(currently I use the dimensions of my screen grob
to find out what I need to know, e.g. LCD\-> SIZE B\->R NIP
gives me the pixel height of my screen on either 49G or 49G+
Actually, the LCD\-> command performs system function DOLCD>
in ROM, which in turn begins with BINT64 BINT131 MAKEGROB
on my 49G (now compiled as 1.24), whereas on my 49G+
it begins with a program which calls the entry point
which tests hardware via BIGAPP? and finally returns
either BINT80 or BINT64, as appropriate.
Thus it would be good to know how BIGAPP? works,
and will BIGAPP? return the right answer
if this special ROM image made for EMU49+ is transferred
into a real 49G; further, is there any other hardware dependency
which might trip up a real calc (or even the original Emu48)
when a 49G+ ROM image intended for Emu49+
is transferred instead to a real or emulated 49G?

Indeed, given your info above,
I can now see this in both my real 49G+ (2.05)
and my 49G compiled version 1.24,
via 161 17 XLIB~ DUP Nosy
Hmm.. does this mean that all 49G+ rom versions have all along
been intended to be capable of making 49G updates as well,
although thus far the only one published,
other than via this trick using special Emu49+ ROM 2.01,
has been 49G version 1.24 (which you have to make yourself,
from a CAS source release provided by BP)?
If so, is anyone planning to make conversion of new 49G+ updates
into 49G updates a more routine matter? (if so, it would always
remain unofficial, although certainly welcomed here, I would think).
About IsApple_ -- is that a non-fixed entry point?
(if so, then one must make model tests indirectly,
by using other stable functions which in turn
deliver model-dependent results).

IIMO the OS think it's 48gII inestead of a real 49g+
thus adapting to the LCD size
What about the Flash and IRAM?
Will they work?

Oh, good -- now all that's left
is for someone to figure out how to transform them :)
Well then, "something's coming,

While the source code is the same between 49g and 49g+, the binary isn't.
Now the patch applied on the 49g+ ROM isn't too complex and I believe it
is possible to reverse it to get a rom that would work on an original 49g
JY
> Just use ROMUPLOAD, no need to transform them.
ROMUPLOAD is currently "Not available"
when attempted on 49G+ (as of version 2.05)
The task at hand is converting a 49G+ ROM file
into an update useful for the 49G;
apparently the only time this has been done before
is when HP created one ROM version for the Emu49+ emulator,
but that version is now a bit obsolete, even for the 49G+
Someone may be working on this project meanwhile;
hope they enjoy success.

Apparently he updated his 49g, but is his update to 2.01 valid, or will
it crash eventually?

right, I updated my 49g with the emulator ROM 2.01-1 of the 49G+. This
is quite easy with EMU48, cause the emulator ROM of the 49G+ works
fine with the emulated 49G. Just replace the ROM-file in the EMU
directory.
Since EMU48 doesn´t contain any ARM-emulation I expect this ROM to run
fine on my 49G.
I haven´t noticed any problems so far but I also admit that I don´t
use the 49G that much anymore (only for SW-Testing of my own SW) since
I got my 49G+.

P.S. if there is need for a detailed explanation how to do it, I write
one if I have the time

Do that please
but 1st of all *test* it to see if it crashes

o Build version 1.24 from BP's CAS source release:
ftp://ftp-fourier.ujf-grenoble.fr/xcas/hpcas/casrelease.zip
(this location will have the recent fix to the "CreateRom"
program, invoked in the very last step).
o Try ROMUPLOAD from the only 49G+ version (2.01?)
for which a special Emu ROM file was ever provided.
There is some question about the latter, e.g.:
http://groups.google.com/group/comp.sys.hp48/msg/22ed9ef8066542b0
No one has as yet provided any general method
for using new 49G+ updates with either Emu4x or HP49G,
although someone may be working on it.

Is there a published list of versions for 49G+
with a summary of what was updated in each version?
Thanks.

Just to clarify, this emulator ROM file (which comes with Debug4x):
4194304 06-07-05 09:09 ROMG+.49G
That's a 49G compatible file, and *not* what you mean above?
And when you said
"the ROM for the 49g+ has specific instructions
that only works on the emulated saturn"
you meant "emulated saturn on the ARM platform,"
rather than on the Emu48/49 Windows emulator?
Thanks again!

Sounds like that might impose some overhead on general operation.
