BSNES SLOW SERIAL
BSNES SLOW ARCHIVE

Overall, it can be seen from all three videos that in general, a good emulator can emulate the underlying hardware with extremely high fidelity for the vast majority of games and gameplay.ДЇidelity isn't a burning issue in modern 8 or 16 bit emulation. So the issue is not the processing power required but simply the fact that the Snes9x and ZSNES developers focused on different features. Now, the TAS videos run doesn't display the same problem, but that was probably run from Snes9x, not ZSNES(technically from a custom Snes9x build supporting re-recording). SDA don't actually accept emulator runs, so the video there is from an actual SNES.

BSNES SLOW ARCHIVE

Here's a ZSNES emulation of the LTTP intro, which you can compare with the Speed Demos Archive run. The more you have to synchronize, the faster your assembly line has to move to keep up.' It completely negates the benefits of pipelining and out-of-order execution. Synchronization is the equivalent of stalling out and clearing the entire assembly line, then starting over on a new product. Take the analogy of an assembly line: one person unloads the boxes, another person scans them, another opens them, another starts putting the item together, etc. Attempting to rely on today's multi-core processors leads to all kinds of timing problems.

BSNES SLOW SERIAL

An emulator is an inherently serial process. The primary demands of an emulator are the amount of times per second one processor must synchronize with another. These are little details, but if you have an eye for accuracy, they can be maddening. On the former, the triforces will complete their rotations far too soon as a result of the CPU running well over 40 percent faster than a real SNES. As an example, compare the spinning triforce animation from the opening to Legend of Zelda on the ZSNES and bsnes emulators.

But emulating those old consoles accurately - well, that's another challenge entirely accurate emulators may need up to 3GHz of power to faithfully recreate aging tech. 'It doesn't take much raw power to play Nintendo or SNES games on a modern PC emulators could do it in the 1990s with a mere 25MHz of processing power.
