3.5” LCD display setup

[screw]

Hi
I recently purchased a 3.5” lcd display as I wanted to make my raspberry pi portable. The thing is it’s a generic no brand. I’ve tried A LOT of things, different drivers etc. no matter how hard I try I cannot get this thing to display retropie all it is doing is showing the boot read outs. It may be a waveshare clone it may not be all I really know is that it is not hdmi it plugs in to the gpio header. All help is greatly appreciated.

Other information:
Raspberry Pi 3 b
Retropie version 4.4

Thanks
