I'm the author. I disagree with this statement. It takes a considerable amount of effort and research to reach cycle-accuracy, especially on the PPU side. Understanding how the PPU pipeline works will take you more time than everything

I'm the author. Everything you need is on the NESdev wiki or it's linked there. A couple of particularly helpful resources are linked in my README. The PPU diagram and the 6502 reference were especially useful. I definitely encour

I'm the author. The reason for the single letters is that those are the actual names of the 6502 registers. Glad you like it overall. :)

To be fair I don't implement all the mappers, but I'm pretty confident the core parts of the emulator (CPU and PPU) are as small as it gets.

Thanks (for calling me the right person). There is a price to pay for power in C++ though. Keeping the code beautiful and readable is often a challenge, as the syntax gets convoluted very quickly. I'm not the biggest fan of the Standar

It's not atomical. Note that the PPU is constantly updated in the middle of the CPU instructions in a way that respects the timing of the original hardware. The relative order of operations between CPU and PPU is respected.
