+# GB-GameOfLife
+An implementation of Conway's Game of Life for the GameBoy
+
+# Project's Backstory
+I started this as my first real programming written entirely in assembly.
+I thought the gameboy was a good fit for that, with its not too complex
+instruction set. I chose Conway's Game of Life because it's quite a
+classic of CS exercises and I thought it would be simple enough to do.
+
+Boy, I was wrong.
+
+I know the gameboy is far from fast enough to update all pixels on
+screen in between each frame. Who would have thought it would also
+not be fast enough to just update its 20x18 tiles? That's only 360
+bytes! In the v-blank, the time between two frames are rendered by
+the Picture Processing Unit or PPU, and where you have access to 
+Video RAM, there's barely enough time to write to a quarter of the
+tilemap. And that's without reading from it!
+
+But there's hope: first, the gameboy has enough video ram to hold
+two tilemaps, so we can double buffer. Second, the v-blank is not
+the only time where you can write to Video RAM, you can also write
+in between the PPU rendering lines! That requires synchronising code
+with rendering but it should be doable.
