Unlike traditional emulators that mimic console behavior through software, FPGA recreates the original hardware at the circuit level. It doesn't just simulate—it behaves exactly like the original system, delivering unparalleled accuracy, flawless timing, and true-to-life performance.

Can directly interface with original cartridges, discs and accessories because it recreates the console at the electrical + timing level. Everything behaves like original hardware.
Runs in software, cannot directly speak to cartridges or many accessories without hacks/adapters. Mainly designed for ROM files and not physical hardware.

Inputs are processed nearly instantly by the hardware itself. You get a responsive experience that mirrors original console behavior, down to the frame.
Input travels through multiple software layers, often adding noticeable delay between button press and on-screen action even with optimizations.

Recreates the original audio hardware at the signal level, ensuring every tone, envelope, and timing nuance sounds exactly as the developers intended.
Audio timing and mixing can drift, resulting in missing notes, incorrect pitch, or noisy samples especially in games with custom sound chips or effects.

Each processor (CPU, VDP) is cycle accurate, executing in parallel at original speeds. Original CD's operate at critical perfect timing for game compatibility. Even the most exotic programming works identically.
CPU and VDP timing are approximated and often tied to the host system rather than original clocks. CD-ROM² streaming is buffered and abstracted, leading to potential audio desync, loading inconsistencies, or stutter.




With Duo, you have the power to choose how to connect. Bluetooth and 2.4g are built right in. Sync up any wireless 8BitDo Bluetooth or 2.4g controller directly to Duo for wireless play. Up to 5 player support. No receivers required.
You can even connect controllers directly via an original-style port and the wired USB ports, too.


TurboGrafx-16, PC Engine & SuperGrafx are coming to Pocket. For the first time since the original TurboExpress in 1990, you can play the entire 16-bit library of TurboGrafx-16, PC Engine & SuperGrafx games anywhere with Pocket.
