The more complicated and fast the original hardware, the more resources that host running the emulator needs to use. Put simply, LLE generally tries to re-implement the way the hardware works in software. These terms stand for Low-Level Emulation and High-Level Emulation. The Audio plugins and Controller plugins are far more similar to any other emulator past, present, and future, so generally aren't as diverse or complicated. The bulk of this page will be regarding the RDP plugins, which are simply called the Graphics plugin. This means many plugins were developed to be fast and accurate running one game, but would sacrifice accuracy of other games to do so. This means many different people have been able to try their hand at handling the Reality Display Processor and Reality Signal Processor which both make up the Reality Co-Processor that handled the graphics in the N64, which was one of the hardest parts of the N64 hardware to emulate quickly and accurately on computers when the N64 released in 1996.
This was originally a way for closed source emulator developers to allow other developers to handle emulation of the different aspects of the console, while the closed source core handles the emulation of the main CPU of the console. Nintendo 64 emulators use a plugin system.
