Emulators function using either low-level emulation (LLE) or high-level emulation (HLE), with the former directly emulating the processes of the original system and the latter merely simulating them. While both methods are commonly used and have distinct benefits, the truer 'emulation' of LLE means emulators that use this method require the system ROM of the original hardware to function. This ROM, known as the BIOS, performs system-critical tasks for many systems, with neither the original hardware nor an LLE emulator of that hardware being functional without the associated BIOS file. In the case of the FunKey S, while the majority of its emulated systems do not require BIOS files, there are two that do: the PlayStation and Game Boy Advance. While some PlayStation games can be emulated without a BIOS file and alternate, albeit slower, Game Boy Advance emulators that don't require BIOS files are available, to properly emulate either system using the default emulators a BIOS file for each is required. As with video game ROMs, BIOS files are protected by copyright restrictions and thus also cannot be legally distributed with the FunKey S. Users may extract BIOS files from PlayStation and Game Boy Advance units that they own and add them to the FunKey S emulators for those systems to improve functionality for the former and enable functionality for the latter. Additionally, while Sega Genesis and TurboGrafx-16 games do not require the presence of BIOS files to be accurately emulated, games for their respective add-ons, the Sega CD and TurboGrafx-CD, do. A tutorial for adding emulator BIOS files to the FunKey S can be found here.
