The Castles of Dr. Creep: 3 Open Source Clones Compared
The Castles of Dr. Creep is a full open-source reimplementation playable on Linux, macOS, Windows and Wii (also sold on Steam), adding a built-in castle Builder for creating or editing levels and local two-player co-op, while keeping its D64 save files compatible with the original Commodore 64 game. The Castles of Doctor Creep is a different kind of project: an EasyFlash cartridge build meant to run on real or emulated C64 hardware, which adds save/load support (not thoroughly tested, per its README) to the original game rather than reimplementing it, and requires supplying your own original C64 disk image plus a separately created 'remastered' disk (Castles of Dr Creep 3 ReM V2) in order to build.
