There's also a video of the game here: https://youtu.be/OGxj_g1ImhM
3. DIFFERENCES FROM THE ORIGINAL
There are several differences that all have to do with Apple II hardware

There are actually 2 programs in this. The 1st is the game, and it's in
src/apple2.
* audio.inc - Routines to make the speaker beep
* defs.inc - Constants and definitions used throughout
* game.inc - The in-game logic, AI etc. The bulk of the "game"
* input.inc - User controls for game and editor
* level.inc - Decompress a level and place the keys
* logo.hgr - 8Kb splash screen in HGR format
* logo.inc - File that simply does an incbin on logo.hgr
* mminer.asm - Where the game starts, initial setup, etc.
* mminer.cfg - ca65 configuration file
* roaudio.inc - Frequency and timing data for music and SFX
* rofont.inc - A ZX Spectrum font
* rolevels.inc - Level layout, tile usage, sprite positions, etc.
* rosprites.inc - Sprite definitions
* rosystem.inc - Helper tables (multiplication, color masks, etc.)
* rotext.inc - All text used in the game
* rotiles.inc - Background tile definitions
* screen.inc - Code related to drawing tiles, sprites, etc.
* sprite.inc - Code for making instances of sprites, coloring them, etc.
* text.inc - In game text and print functions
* ui.inc - User facing screens (title, scroller)
* variables.inc - All variables (scores, instance buffers, positions, etc.)
* Willy.inc - All logic relating to the movement of the main character, Willy

The second is the ProDos loader that will auto-load the game. It's in the
src/apple2.loader folder. It has these files (all provided to me by Oliver
Schmidt)
* loader.cfg - ca65 configuration file
