I did our banners. Though I don't have the font Quicktype Mono. Sorry I didn't save the psd. But I can always redo it & save the psd if you want but you would have to edit the text yourself. Here is what I got:
If you want to make a support banner, here's what it should be:
Short height, long width -- Idrc about the exact dimensions of it
Dark blue/gray background
Rain in the foreground
Pokemon logo + "Hyetology" underneath (I use white, Quicktype Mono, all caps, the "H" a bigger font size than the rest)
"An Emerald ROM hack by hinkage" in white, top right corner, with the Steven overworld to the left of it.
