GTron 4-in-1 Retro
This is a review of an adapter manufactured by Gtron that allows
you to use your original console controllers on your Wii's GameCube port. When I wrote this review it was one
of the only retro adapters available. While it does work, you can notice a slight lag. As a
result, I'd recommend the other options listed on the main Wii Retro Adapter
To test the adapter, I plugged the adapter into my Wii’s Gamecube
Port 1 and plugged each of the original controllers into the adapter one at a time. Each time, I went
through the same process: I’d use the Wiimote to navigate and select the Virtual Console game, then
once the game launched, I’d put down the Wiimote, pick up the original controller and start
NES, SNES and Genesis (with the 3-button controller) worked
great. No configuration, no setup, just literally plug and play. All of the buttons on each of
the systems were automatically mapped out perfectly and it was exactly like I was playing it on the original
console! I can’t stress this enough: No setup at all, it just worked!!!
The first problem I ran into was with the N64 controller.
The adapter has a toggle switch, so I tried different combinations to make sure I wasn’t doing anything
wrong. I tried plugging it in with the Wii off and the adapter in the N64 position before powering
on. I also tried starting it with the switch in the other mode and then moving it to the N64 position
after booting. No matter what I tried, some of the buttons on the N64 controller would work some of the
time and the analog stick almost never worked. I tried two different controllers and I also tested them
on an original N64 system to double check that they were both in good working order. It seems that N64
controllers just plain don’t work. Other reviews online have had different problems with the N64
controllers, but all agree it’s unusable.
The second problem I ran into was the
Genesis 6-button controller. None of the top buttons were recognized in any game. The back of the box
it came in shows a picture of the Genesis 6-button controller, so one would assume that it should have been
compatible. Unfortunately, other online reviews also claim the 6-button controllers won’t work, so I’ll just
assume it’s not supported.
After I was done testing each controller with the Virtual Console
games, I tried each one with it’s corresponding emulator (my Wii is modded, of course). For NES, SNES
and Genesis (3-button controller), it was literally plug and play, just like the Virtual Console games.
The controllers worked flawlessly with their corresponding emulators and no setup was needed. The only
“config” that had to be done was on the Genesis emulator, but all I had to do was tell it I was using a
Gamecube controller instead of the Wiimote. It was only one quick setup option though and still no
button mapping required...although here’s a tip to anyone using the Genesis emulator: Set up the Wiimote as
“Controller 2”, so you can still use the Wiimote for savestates and emulator control. Unfortunately,
the 6-button controller also didn’t work with the emulator, even after making sure to select the 6-button
controller in the emulator setup.
FYI, I didn’t bother trying the N64 controller with an emulator,
because I’ve never found a N64 emulator that worked well on the Wii.
Anyone who has ever modded the original Xbox and added emulators
knows exactly how long that process could have taken...I was expecting to spend forever setting up button
mappings and saving configurations, but no!!!! NES, SNES and Genesis (3-button) worked
Another thing to note is that since the adapter has a cable that’s
about 6 feet long, it acts as an extension cord as well. This is a big help for people like me that
have gotten used to wireless controllers and forgot how short the cables of the older game systems were (I
remember we used to drag the consoles out to the center of our living room when we played, so the controller
cord could reach the couch) The length of the adapter’s cable allowed me to leave my Wii where it was
under my TV and sit on my couch, with enough slack on the original controller to be completely
There is one other downside of the adapter. Since it plugs
into the Gamecube port, it can only support games that allow being played by the Gamecube controller.
Virtual Console games are compatible with the Gamecube port, but most WiiWare games are not...a total
bummer. I was hoping to play Sonic 4, Mega Man 9 & 10 and A Cave Story, all with the original NES
or Genesis controllers, but no such luck.
My conclusion: I was able to play all the way through Sonic
and Knuckles with the Genesis controller and played all the way through Zelda: A Link To The Past with the
SNES controller. Both worked great and while every once in awhile I noticed some button lag, it’s not
bad enough for casual gamers to notice (although I imagine hardcore gamers would definitely
Unfortunately, if you require N64, 6-button Genesis, or WiiWare
support (or want an adapter without much lag), check out the other options on the main Wii Retro Adapter page.
