alt Hacker News...Forth? Wow. I wonder how much code change was necessary between the various systems. It's hard to imagine a Megadrive Forth compiler, but then again, the game was on several other M68k systems so maybe it wasn't as hard...

It's.. not a compiler (besides I had Forth on my C64). Maybe one can call it a translator to ad-hoc bytecode. I also had USCD Pascal on that C64 which translated to bytecode. This was more JVM-like. So nothing hard about it.

It is really, really easy to write a Forth interpreter (You can write a simple one in an afternoon). It's often the first software written for an architecture. The structure of Forth means that the hardware-dependent parts are contained in a small number of words (sort of like functions in other languages but not exactly). Forth can be implemented on tiny microcontrollers; a Megadrive would be luxury.
