#BSNES ACCURACY SOFTWARE#
Unless the software does everything in the exact same way the hardware used to, the game remains broken. One can imagine the frustration of instantly losing three hours of progress and being met with an unbeatable game. Yet once you reach stage 6-1, you can quickly spot the difference between an accurate emulator and a fast one: there is a switch, required to complete the level, where the game will deadlock if a rare hardware edge case is not emulated. At first glance, it appears to run fine in any emulator. This is an SNES platformer with no save functionality, and it's roughly 2-3 hours long. So the question becomes: if we can achieve basic compatibility, why care about improving accuracy further when such improvement comes at a great cost in speed? Two reasons: performance and preservation.įirst, performance. In truth, most software runs with great tolerance to timing issues and appears to be functioning normally even if timing is off by as much as 20 percent. Apparent compatibility is the most obvious measure of accuracy-will an old game run on my new emulator?-but such a narrow view can paper over many small problems. Put simply, accuracy is the measure of how well emulation software mimics the original hardware. In this piece we'll take a look at why accuracy is so important for emulators and why it's so hard to achieve.
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.
#BSNES ACCURACY PC#
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. He wants to share his thoughts on the most important part of the emulation experience: accuracy. Today we present another point of view from a gentleman who has created the Super Nintendo emulator bsnes. Emulators for playing older games are immensely popular online, with regular arguments breaking out over which emulator is best for which game.
