pokegb VS metroboy

This is the same person who made pokegb, a similarly tiny Game Boy emulator: https://github.com/binji/pokegb

fair point, the actual source is ~5000 bytes not counting whitespace, maybe should've said that instead. You can see some of the unobfuscated source here if you're curious: https://github.com/binji/pokegb/blob/d73d6ac6ec76abf8a4a9904c992e9b17c49992d8/main.cc

pokegb.cc (as 3 pokeballs): 9956 bytes

The posted Github link appears not to work; try this one if you want to be wowed.

If you want to go deeper, you can look at the reverse engineered schematic of most of the stuff except the CPU core in the DMG-CPU-Inside project. You could also consult the MetroBoy project, which builds on the previous project and aims to be accurate pretty much down to the logic gate level.

Well then, here's the ground truth - https://github.com/aappleby/MetroBoy/blob/master/src/GateBoyLib/GateBoyPixPipe.cpp

First I would try to deduce the timing from this gate-level simulation of the game boy, but the master branch was broken at the time, so I didn't manage to compile it. So, I tried deducing it from its underling reverse engineered schematics, but it would take too much time, if it even was possible.

You might find my hobby project interesting - https://github.com/aappleby/MetroBoy

Reminds me of GateBoy, which was posted a while back: https://news.ycombinator.com/item?id=28396927, https://github.com/aappleby/MetroBoy

GateBoy runs surprisingly fast for a gate-level simulation.
