Castles of Dr. Creep is a 1984 Commodore 64 game written by Ed Hobbs and published by Broderbund Software.

This project is an open source rewrite, allowing you to play the game using an image (D64) of the original disk. Additionally, a Castle Builder has been added allowing the player to modify existing castles, or build new ones from scratch.

Currently it can compile and play on both Windows, Nintendo Wii, FreeBSD, MacOS X, and Linux (Ubuntu specifically has been tested).

Installation

Extract the zip file to the apps folder to your SD card.

In order to run the game, you will need to supply your own Commodore 64 Disk Image (D64) of The Castles of Dr. Creep, which should be placed in the game's data folder. This file may have any name, but the D64 extension must remain.

A Channel WAD is also provided.

History

Ed Hobbs, the programmer of the game, sheds light on the difficulties he faced while reverse-engineering the 6502 object code to C++. In the early days of the C-64 assembler, it was limited and could not handle programs larger than 16kb, so Hobbs had to write and assemble the source code on an Apple II and then transfer the binary to the C-64 through the joystick ports of the respective computers, marking his first experience with a "computer network". Despite the game not being able to run on the Apple II, it still played a crucial role in the creation of "Dr. Creep".

One of the major challenges was to fit the entire source code onto a single 144 kb floppy disk that was compatible with the Apple 6502 assembler. To do so, Hobbs had to remove all comments from the code, leaving no room for them. He maintained a notebook with hundreds of pages of flowcharts and data-layout diagrams to keep track of the code and understand what was happening in the code.

Furthermore, there was no C-64 debugger available, adding an extra layer of complexity to the programming process. Hobbs also lacked a level editor, and had to draw out the levels on custom graph paper and then hand-code the level data.

Overview

The Castles of Doctor Creep is a puzzle platform game in which your task is to escape from 13 different castles that are filled with traps, monsters, and mazes.

Each castle is a series of connected rooms that you travel through; many rooms have multiple entrances and exits. In some of the more intricate castles, you must visit certain rooms multiple times, entering and exiting using different doors.

You can learn more about the game (along with many game tips) on C64-Wiki.

Save game support

D64s will be created in the data\save folder, and all save games will be stored in these files.

These files are compatible with the original Commodore64 game, and in return the original save games are supported.
