Better than BO 2 ? <| sep |> Hitler Did Nothing Wrong <| sep |> So has Robinson . He played like 5 minutes tonight . <| sep |> The thing about challenges like this is that they generally boil down to mimicking the aesthetics of NES games , which is all well and good and there are plenty of people who are already making games with NES aesthetics at varying degrees of faithfulness but it ' s only part of what makes them NES games to begin with . Remember that the strictest hardware limitations such as the limited processing power of a 1 . 8 MHz modified 6502 CPU , or the highly restrictive bandwidth for transfers between the CPU and VRAM are the hardest for a developer to wrap their head around and the hardest to simulate , while several of the most wellknown and most readilyapparent restrictions are also among the easiest to circumvent on real hardware . For example , the smoothness of animations , both sprite and background , involves a complex and unavoidable tradeoff between tileset flexibility , ROM capacity , VRAM bandwidth usage , and cartridge complexity , ultimately arising from the fact that the CPU can realistically transfer less than 256 bytes per frame to VRAM while the screen is active and this tradeoff has consequences for other decisions as well . Meanwhile , the limitation of 256 unique background tiles at one time has been exceeded in at least two different ways .
