Neo2USB vs SNES2Neo: Which Adapter for Neo Geo?

Compare the Neo2USB and SNES2Neo adapters for Neo Geo. Learn which one lets you use your original controllers on MiSTer FPGA or modern SNES pads on your AES.
Quick answer
If you want to use original Neo Geo controllers on MiSTer FPGA or PC, get the Neo2USB. If you want to use SNES controllers (wired or wireless) on your Neo Geo AES, CD, or consolized MVS, get the SNES2Neo. Both offer roughly 1ms latency but serve opposite directions.
One adapter goes in, the other goes out
The Neo2USB lets your original Neo Geo DB15 controllers work on modern hardware like MiSTer FPGA and PC. The SNES2Neo does the reverse: it lets SNES controllers (wired or wireless) work on your Neo Geo AES, Neo CD, or consolized MVS. They are not interchangeable, so your choice depends entirely on which hardware you want to connect.
Latency is similar, but the trade-off is compatibility
Both adapters advertise roughly 1ms of latency, so input lag won't be a deciding factor. The real trade-off is in controller and platform support. The SNES2Neo works with virtually all SNES wired and wireless controllers (including BT and 2.4GHz dongles) and uses the Neo Geo CD button layout. The Neo2USB uses open Daemonbite firmware and provides all four directions, Select, Start, and four action buttons, but it does not support 6-button arcade sticks out of the box.
Trade-offs at a glance
- Platform direction: Neo2USB: original Neo Geo controller → MiSTer FPGA or PC. SNES2Neo: SNES controller → Neo Geo AES/CD/MVS. Choose the direction that matches your hardware.
- Controller compatibility: SNES2Neo works with virtually all SNES wired and wireless controllers (BT and 2.4GHz). Neo2USB works with standard Neo Geo controllers but not 6-button arcade sticks without modification. If you need 6-button arcade stick support on PC/MiSTer, the Neo2USB may require extra soldering.
- Button layout: SNES2Neo uses the Neo Geo CD controller button layout. Neo2USB passes through the original Neo Geo layout. If you prefer the CD layout, the SNES2Neo is set up that way by default.
Product facts
- SNES2Neo Ultra Low Latency SNES Controller Adapter for Neo Geo - Retro Frog: The SNES2Neo allows you to use virtually all Super Nintendo wired and wireless controllers on your Neo Geo AES home console, Neo CD or consolized MVS system. It works with wireless dongles for both BT and 2.4GHz controllers and uses the Neo Geo CD controller button layout. If you already own SNES controllers (or want to use a modern wireless SNES pad), this adapter opens up many more controller options for your Neo Geo hardware.
SNES2Neo Ultra Low Latency SNES Controller Adapter for Neo Geo - Retro Frog - Neo2USB Ultra Low Latency Neo Geo Controller Adapter for MiSTer FPGA & PC - Retro Frog: The Neo2USB is a DB15 to USB converter that uses open Daemonbite firmware and provides on average 1ms latency. It supports all four directions, Select, Start, and four action buttons, but does not support 6-button arcade sticks without additional soldering and reflashing. This is the simplest way to use your original Neo Geo controllers on MiSTer FPGA or PC, but you may need extra work if you want to use a 6-button arcade stick.

Which adapter should you buy?
Best for
- Gamers who want to use original Neo Geo controllers on MiSTer FPGA or PC (Neo2USB)
- Gamers who want to use SNES controllers (especially wireless) on their Neo Geo AES, CD, or consolized MVS (SNES2Neo)
Not for
