Hello friend! Let me see what I can do... I'm pretty sure that the GameEx Logo X file was done in Google Sketchup. You can learn more about creating your own 3-D images by going here. These are set individually in each emulator's setup. Some theme images are for core GameEx features, and ned to be named the same to work. You can additionally add _Foreground to the page and have it overlayed onto your image. So if you did one for N64, then N64.PNG is the background and N64_Foreground.PNG is the overlay. To apply them you simply open up at emulator's settings and point GameEx at it under "Custom Emulator Background".The flags are for GoodMerged sets (when you extract Super Mario Bros.7z for example, the ones with (J) display the Jap flag, (U) displays the USA flag, etc. You could achieve this simply by putting it on the "background" page I mentioned above, and the rest of the elements on your _Foreground. I hope that's helpful.
