Thanks for reaching out! Glad you got your buttons working! 
You're right there's no resolution changer for rockchip yet (I'm working on one, amongst the chaos haha), so it makes changing your screen around a bit confusing. I've patched the emulators to run at a set resolution in order to optimize performance.
There is an aspect ratio setting in the recalbox menu that applies only to libretro (retroarch) cores, but I don't think it works on the current release. I've patched it in this next release, however, so I expect that will resolve all retroarch cores.
Mupen core screen sizes should be configurable thru the cfg files (read the readme on my github for detail). For your custom aspect ratio, don't adjust the heights listed, only the widths, and be mindful of the custom aspect setting I've added (details in the readme also).
But ppsspp and reicast are currently hard coded to a resolution that can't be adjusted by config files. I wasn't sure if there was going to be a need for this. So what I'll try to do is to re-work my graphics-stack-wrapper patch for the emulators to query a desired resolution inside recalbox.conf to provide the feature you need. It may not be available in the upcoming release, but I'll see what I can do But until then, I expect you should be able to get all but PSP and Dreamcast corrected using the configs.
