Robert Heaton - tweeting as @RobJHeaton - describes himself as a one-track lover down a two-way lane. I love that kind of linguistic creativity.

But that's not all. Robert also has a heart for developers. Namely, for the very special subset of developers, for whom a very special part of hell is also reserved - developers of Gameboy emulators. 👹

Robert's project Gameboy Doctor is a tool, that belongs to the debugger species, but must have taken a turn somewhere, sometime in evolution. And in a good sense.

The software helps you identify bugs in your own emu faster and easier by letting you run test ROMs, and simply log the register contents after each instruction.

Due to the deterministic nature of our little friends made of silicone and plastic, the respective state after an operation can be compared to the "should-be", and Voilà, ready is the debugging recipe.

Great idea. Ingenious implementation. Real killer for ... Gameboy emu developers.
