Realtime Romhacks Ep.01 - How to hack the scrolling in Konami Wai Wai World with NES Assembly.
7Realtime Romhacks Episode 1.
In this hack I show you how to change Konami World so it scrolls when centered, instead of when walking against the edge. It's not meant to teach 6502 ASSEMBLY, but to show the process of Romhacking, mistakes and all. I'm hoping it can open the gate for people that aren't sure where to start.
