Using ICU64 to see how games work

Here's a group of videos demonstrating some of what I've discovered using ICU64

(like JavaScript, C64 also stored stored ints as floats)

Thanks to ICU 64 I was able to discover a myriad of information. I've created a map using WebGL 2D which I follow along in this video

This 2600 game isn't using ICU64, but I did modify the game a bit thanks to someone releasing the assembly code with comments. Used it to noclip which allowed me to see room inter-connections.
