Comes with a PICO-8 license. 1024*768 10 inch screen for a pixel-perfect 6x scale.

Where did you get this?

On the Pimoroni store

Just bought this, Can't even run pico-8 on this thing, so dam difficult without instruction....

That's very weird that they advertise "bundled with PICO-8" but don't include a pre-made SD card. The 2020 instructions don't mention PICO-8 installation either. In what form do you get the license? Is it a serial number on a piece of paper? The product page mentions a "cheat sheet"?

This old RetroPie tutorial was intended specifically for Picade, if that helps. It was written for people with some Linux experience, and I haven't tested it in ages. Seems like there's an opportunity for Pimoroni to do what ClockworkPi did and automate the installation with a bundled script.

I like Pimoroni stuff and I have two Picades. Now I'm jealous I don't have one with a PICO-8 sticker on the box. :P

Have you checked out the official tutorial

Is your problem building the kit or installing the software?
