Awesome

Common

• Place tetris.gb in the tools/ directory, and web/ directory
• Former is used for scripts, and tools/cmp.sh, and the latter for web visualisations

Building

• Install RGBDS v0.6.1
• Run make within the disasm directory
• Run tools/cmp.sh to compare built ROM against original ROM

Web

• Start a web server within the web/ directory, eg python3 -m http.server
• Navigate to the root page to see a list of game screens and sprites

Project Structure

• disasm
  • code - dissected and commented asm that runs the game
  • data - large blocks of data, layouts are in .bin files
  • gfx - pngs of 1bpp and 2bpp data
  • include - constants, hardware definitions, ram, macros and structs
  • includes.s - imported definitions, excluding those that need building, eg ram
• tools - misc tools to help with disassembly
• web - the html+js in 1 file to visualise
  • docs - reference images, and flow .drawio

Note on improvements

The project serves to describe everything that makes the game function as it does. Some things are not completely clear from the outset. If you need a full guide on a particular concept, eg sound engine, or some part of the disassembly needs further clarification, please feel free to raise an issue
