==History== | |||
As a programmer, I appreciate the difficulty of reverse-engineering the 6502 object code to C++. When I wrote the game, the C-64 assembler was very primitive (it couldn’t handle programs larger than 16 kb), so I had to write and assemble the source code on an Apple II, and then transfer the binary to the C-64 through cables connected to the joystick ports of the respective computers (my first experience with a “computer network”). So even though the game could not be executed on the Apple II, this computer still played a vital part in Dr. Creep’s creation. | |||
One of the biggest problems was that the source code had to fit onto a single 144 kb floppy disk in order to work with the Apple 6502 assembler. The only way to do this was by eliminating all comments in the source code—there just wasn't any room for them. I maintained a notebook comprising hundreds of pages of flowcharts and data-layout diagrams. The nodes of the flowcharts were labeled to match the nametags in the source code. In this way, I was able to visually grasp what was going on in the code, and still fit it into the requisite space. | |||
Furthermore, there was no such thing as a C-64 debugger, which added an additional twist to the programming. | |||
I also didn’t have a level editor. I drew the levels out on custom graph paper, and then used these drawings to hand-code the level data." | |||

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.
History
As a programmer, I appreciate the difficulty of reverse-engineering the 6502 object code to C++. When I wrote the game, the C-64 assembler was very primitive (it couldn’t handle programs larger than 16 kb), so I had to write and assemble the source code on an Apple II, and then transfer the binary to the C-64 through cables connected to the joystick ports of the respective computers (my first experience with a “computer network”). So even though the game could not be executed on the Apple II, this computer still played a vital part in Dr. Creep’s creation.
One of the biggest problems was that the source code had to fit onto a single 144 kb floppy disk in order to work with the Apple 6502 assembler. The only way to do this was by eliminating all comments in the source code—there just wasn't any room for them. I maintained a notebook comprising hundreds of pages of flowcharts and data-layout diagrams. The nodes of the flowcharts were labeled to match the nametags in the source code. In this way, I was able to visually grasp what was going on in the code, and still fit it into the requisite space.
Furthermore, there was no such thing as a C-64 debugger, which added an additional twist to the programming.
I also didn’t have a level editor. I drew the levels out on custom graph paper, and then used these drawings to hand-code the level data."
