Using a different screen from the tutorial for a pi zero 2 emulator

I tried to follow this "tutorial" : https://www.thingiverse.com/thing:1334253 , but had to replace the Adafruit display with a Waveshare display. https://uk.pi-supply.com/products/adafruit-oled-breakout-board-16-bit-color-1-5-wmicrosd-holder https://www.waveshare.com/1.5inch-rgb-oled-module.htm The driver is the same so I thought it would be the same. The original post on thingiverse isn't detailed at all so I followed this tutorial https://www.youtube.com/watch?v=E0IuDpsUiBU , which can be summed up with this txt file https://www.dropbox.com/s/65erp9ujegss8lq/Nanogameboy.txt?e=8&dl=0 What do I have to change ? I finished the software part but now I couldn't even get an output over the HDMI anymore and the screen isn't lighting up.

What OS do you use?
