Ok.  Many people mailed me suggesting I post this list to 
the whole IML.  When Imagine 3.0 is available I'll repost
an updated list.

 
If you have any problems with this modification:
1) Don't Blame me for your Guru.
2) Send me E-mail with your config (a2000,040,Retina,etc..)
   I'm curoius to see what causes Imagine to fail 
   with this modification.
 
 
 
Ok, here's how it works...
 
Get a filezapper type program. (NewZap DPU FileZap Hex etc...)
 
Look up your version of Imagine on the chart below.
(If your version is not listed, Email me and I'll see if I can 
make one for it.)
 
Edit the executeable at the bytes indicated in the chart. The block #s and
byte #s are shown in decimal.  The hex numbers in parenthesis are the hex
versions of the block numbers.  The bytes to modify are, of course, in hex.
Replace the resolution you  find there with the resolution you want.  Then
save the new file. (I don't have to remind you to keep a backup of Imagine
on hand!)
 
Notice that Imagine automaticly doubles the vertical resolution for use in
interlace mode.  So, if you want vertical resolution of 462 then you must
tell it to give you 231.  (231 = 00E7 in hex)

Impulse told me, in the past, that Imagine is made to run ONLY on a 
640 x 400 screen.  I was told that if I changed it, I would do so at my own
peril.  I pass this information on  to you.
 
One Final Note:  Imagine PC users have a whole different program than Amiga
users.  This modification will not work on the PC version.  I would guess
that a simmilar modification for the PC version would be more  complicated,
given that VGA modes are more complicated than Amiga modes. I would be very
interested to see someone try though.   Imagine Imagineering on a 486DX2/66
with a 1024 x 768 editor screen. Now imagine Impulse telling you it will
never happen.
 
Thanks to Juha Kallioinen of Finland for the PAL numbers.
