Strange Sonic Colors Ultimate Glitch is Real, and Makes Colors a Little Too Bright

It looks like Sonic Colors Ultimate is having a bit of a rocky launch. Though we have had a rather pleasant experience with it so far, the Sonic community has been finding and documenting numerous glitches within the game, both large and small. We’ve experienced a few of these smaller glitches, as Dreadknux noted in his review, but there’s been a particularly bad Nintendo Switch glitch that has been garnering lots of attention and controversy.

The controversy stems from allegations that these glitches are being faked in Yuzu, a Nintendo Switch emulator. While that certainly has been true for a few, the most notable Switch glitch (which I like to call the “rainbow Sonic” glitch) is most definitely real, and I have just been able to confirm it.

So how is this glitch activated? It requires a few steps. Firstly, all six worlds need to be unlocked. Secondly, the player has to enter and immediately exit a minimum of four separate worlds. The glitch gets worse when this is done six times. From there, playing any stage appears to activate the glitch. After completing or exiting a stage, the glitch appears to immediately deactivate, and the second step needs to be redone to reactivate it.

If you suffer from epileptic seizures, we do NOT recommend doing this, as lots of flashing lights can be involved. If you don’t, the experience can be…trippy. Characters can glow bright colors, Sonic’s model can be swapped with a shark torpedo badnik, graphics can disappear and become corrupted. Some speculate that it could be a memory leak, though no one at Sonic Stadium has the expertise to say that with confidence.

We’re not linking to a video right now, but this should give you an idea of what it’s like.

What we can say, is that it appears to be a glitch that is difficult to activate by accident. Four people on our staff have access to the Switch version, and none of us have come across it by accident. I had to follow instructions online to activate it.

You should be able to exit and enter a world up to three times without activating the glitch. The Switch this was tested on was a launch model, and was downloaded onto a SanDisk Ultra 10 speed SD card. We haven’t tested it on the Switch’s internal memory as of this writing.

Sonic community Manager MiniKitty has confirmed that a patch is in the works, and that the development team is listening to feedback while assessing it. Hopefully, this glitch will be among the ones addressed.

  1. One problem I have with the game is that Sonic sometimes move on his own and because of that, I died in one of the levels.
