Creating an Expo app in 2023

12th July, 2023. I'm going to try creating an iOS app called Paranovel, using Expo. My environment for mobile app dev (Xcode, Ruby, etc.) should be in reasonably good shape already as I frequently develop with React Native and NativeScript.

Creating the app

Go to https://docs.expo.dev, and see the Quick Start: npx create-expo-app paranovel

This runs with no problem, then I get this macOS system popup:

type Props = {
  targetSize: [number, number];
  color?: string;
  angle?: number;
  style?: ViewStyle;
};

const SkewedBackground: React.FC<Props> = ({
  targetSize,
  color: _color,

WARNING: OUTDATED TUTORIAL. I will get around to updating this at some point, but for now I don't recommend following this tutorial to build the apps.

Seen all the tutorials for building RSDKv5(U) on Mac that you can muster but still haven't gotten it up and running yet? Well, I hope you can handle one more, because this will finally be the one to fix it! I can guarantee it because I was in your shoes and had to figure all this stuff out myself. This is a text tutorial for learning how to decompile RSDKv5(U) and run Sonic Mania Plus or Sonic Origins on your Mac.

How to build RSDKv5:

Step 1: Install Xcode and the command tools (the command tools can be installed by running this command: xcode-select --install but only after installing Xcode). If you already have them, move on to step 2.

In computing, memoization or memoisation
is an optimization technique used primarily
to speed up computer programs by storing
the results of expensive function calls and  
returning the cached result when the same
inputs occur again.
