Intro to ROM Hacking: Ghost House
09 June 2020
A long time between updates! I've been distracted by working on ScummVM's Macromedia Director engine, but it's mostly bugfixing and I couldn't find a good focal point. So on a whim I made this! The previous video took maybe a week, this was a good test of writing/filming/editing in two days.
In this video Scott takes apart "Ghost House" by Sega, and figures out how to remove the obnoxious screen flashing effects by reverse engineering the Z80 code. This contains a full step-by-step explanation of how to use the MAME debugger for hacking ROMs, even if you don't know assembly language!
