- b
BIOS
A BIOS (Basic Input/Output System) is the firmware that ships baked into the original game console hardware — boot code, system menus, hardware initialization routines.
- c
Cheat code
A cheat code in emulation is typically a short string (Game Genie, Pro Action Replay, or PAR format) that patches a specific memory address to a fixed value at runtime.
- c
Core
In libretro / RetroArch terminology, a core is a single emulator implementation packaged as a shared library that conforms to the libretro API.
- c
Cycle accuracy
A cycle-accurate emulator reproduces the original CPU's behavior on a per-clock-cycle basis, not just at a per-instruction level.
- f
Frame pacing
Frame pacing is the consistency with which the emulator delivers a new frame to your display.
- f
Frontend
A frontend is the host application that loads emulator cores, presents the game-selection UI, handles input bindings, and manages save data.
- p
IPS / UPS patch
IPS and UPS are two binary patch formats used to ship ROM modifications without distributing the modified ROM itself.
- m
Mapper
A mapper (or "memory mapper") is custom hardware on a game cartridge that bank-switches more ROM and RAM into the console's narrow address space than a flat layout could fit.
- o
Overclocking
Emulator overclocking runs the emulated CPU faster than the original hardware, smoothing out games that suffer slowdown when many sprites or particles are on screen.
- r
Rewind
Rewind is an emulator feature that lets you scrub backwards through the last few seconds (or minutes) of gameplay, undoing your last actions.
- r
ROM
A ROM (Read-Only Memory image) is a binary copy of the contents of a game cartridge or disc.
- s
Save file
A save file (or "in-game save") is the file the original cartridge / disc would have written to its battery-backed SRAM, memory card, or save chip.
- s
Save state
A save state is a snapshot of the entire emulator memory (CPU registers, RAM contents, audio buffers, video state) written to disk in one atomic write.
- s
Shader
A shader is a small GPU program that post-processes the emulator's output frame before it reaches your screen.
