Help on framebuffer copy on small LCD (NanoPi NEO)

Hello people,

I'm using Armbian 5.30 - kernel 3.4.113 on a Nanopi NEO. and I'm relatively new to this stuff, so please bear with me.

I successfully managed to install an LCD screen on SPI (ILI9341) using this command:

sudo modprobe fbtft_device custom name=fb_ili9341 gpios=reset:1,dc:201,led:6 speed=16000000 rotate=90 bgr=1

So far so good, but the resolution of the screen is too little and can't load anything - for example Dosbox. I would want to replicate the trick that already exists on Raspberry/Raspbian, and that is to framebuffer a higher res screen (at least 640x480) on the tiny LCD's resolution of 320x240.

This is the program that is used for Raspberry, for reference:

Can someone please tell me if is possible?

Thank you
