D Byte Pusher

An implementation of the BytePusher virtual machine, written in the D language and using the Derelict SDL 2 bindings.

Building

dub build

On Windows you will need a 2.0.2 or 2.0.3 SDL2.dll inside bin/.

Usage

You can start DBP from the command line, passing the path of a memory dump (.BytePusher), but you can also run it directly by double-clicking it.

You can always access the main menu by pressing ESC. SPACE pauses and resumes the execution.

DBP has a feature to automatically pause the execution once a HALT instruction is reached (a JUMP to, and the PC pointing at the current adress). If you try to resume the execution by pressing SPACE then the PC will be increased by one instruction. It's useful for debugging, but may result in unexpected behaviour too!
