FPGA & MiSTer Accuracy
FPGA & MiSTer accuracy refers to the ability of the MiSTer project, which uses Field Programmable Gate Arrays (FPGAs), to precisely replicate the hardware behavior of classic gaming consoles and computers. By re-creating the original circuits at the hardware level, MiSTer achieves high compatibility and timing accuracy, resulting in gameplay and audiovisual output that closely matches the experience on original devices, surpassing most software emulators.

❓ Frequently Asked Questions
What is FPGA and how does MiSTer use it?
FPGA stands for field-programmable gate array, a reconfigurable chip that can implement digital circuits. MiSTer uses FPGA cores to recreate the original hardware logic of retro consoles and computers, enabling high hardware-level accuracy.
What does 'accuracy' mean in this project?
Accuracy refers to how faithfully a MiSTer core reproduces the original hardware's behavior, timing, and peripherals—ideally cycle-for-cycle.
What is a MiSTer core?
A MiSTer core is a software description that runs on the FPGA to emulate a specific system (for example, a particular console or computer). Each core aims to replicate that system's hardware behavior.
What factors influence accuracy and compatibility?
Core design quality, available FPGA resources, timing implementations, and how ROMs/BIOSes and peripherals are emulated all affect accuracy and compatibility.
Is MiSTer perfectly accurate to the original hardware?
Many cores are highly accurate, but perfect replication for every title isn’t guaranteed; some quirks or timing edge cases may differ.
