      If it appears in portrait then you have the Portrait mode PmmC loaded, you need to change it to one of the ones listed below

            I don't get it!
            Either way, whichever of those firmwares it comes with, it should show an image properly whether it's in landscape mode or not?
            Let's say it shows the image wrong way round then I can make it the right way round, but why does it show it fuzzy?
            I am a bit confused now!

              It's not fuzzy, it's wrapping around because it it is a 320x240 image trying to display on a screen in 240x320 mode.



              I'll try and show it using text, say you had a text window 8x5 and it contained the following:-



              11111111

              22222222

              33333333

              44444444

              55555555



              If you tried to 'flow' the same data into a window that was really 5x8 it would still fill the screen, but it would look like this



              11111

              11122

              22222

              23333

              33334

              44444

              44555

              55555



              Hope that makes sense



              If you changed your GC to be 240x320 it would look better, but I don't think that's what you are after, you need to change the PmmC.

                Ok.....
                The image is 320x240. If I change it with Photoshop and make it 240x320, would it work?

                  I would expect it would then look ok.

                      Did you also change the command to 240x320, as well as the GC sreen size and position?

                          Can you show me the complete commands you are sending to the display?

                              I asked

                              Did you also change the command to 240x320,
                              You said "Yes"

                                This is what the TXT file gave me after I built it!!!
                                Unless the GC software is not producing the correct code, I don't know what to do!
