Limited Run Games sells cartridge that bricks your NES

When you press the A button on an NES controller, you send a signal directly to the NES that interrupts the CPU with an input, which triggers the instruction to make Mario jump. When Mario jumps, his screen coordinates change, which means the picture processing unit is getting commands directly from the processor to change where the pixels are located, which is outputted over the coaxial cable or composite cable, depending on how your NES is hooked up to your TV. Both are analog signals that get piped directly in, no conversion necessary, so that's why there's no lag whatsoever.

An emulator, even with run ahead enabled, is still running on a PC with a USB or Bluetooth input that the computer polls, rather than the input interrupting the CPU. It works like this:

It minimizes lag by just running multiple copies of the game behind the scenes, with each copy of the game having one of every button being pressed on the next frame, and whatever button you push determines which copy of the game gets outputted to your screen, so that the rendering doesn't have to wait for you. It's a great solution, but it doesn't reduce lag even lower than an old console hooked up to a CRT, because that is physically impossible. Thank/fuck you for getting me all pedantic on this subject.

You really have no clue what you're talking about do you?

That's around 27% of the fun though

The genisis has a massive home brew scene as does the Dreamcast. The dreamcast alone gets more exclusives a year compared to the ps5 !g*mers

The modern part is the port. It's always been an NES game.

Also Yuzo Koshiro is making a MD shooter and it's had plenty of homebrews like Xeno Crisis, Paprium and the upcoming SotN port.

Atari 2600's had crap since the 90's and there are regular competitions for 7800 and Lynx homebrews. Both of them probably have more homebrews than official games at this point.
