The hotly-anticipated “Super Mario 3D All-Stars” collection finally released on Friday for Nintendo Switch, but a few less-than-scrupulous players are experiencing a huge bug.

The collection – which contains “Super Mario 64,” “Super Mario Sunshine,” and “Super Mario Galaxy” – leaked online several days prior to its official release, allowing players with modded Switch consoles. Now, it appears that anyone playing the game this way is experiencing massive crashes, a side-effect of using illegal means to access it

A Twitter user under the name “Robin64” explained that the most recent Switch firmware contains a specific “module” that the emulators in the “3D All-Stars” collection use to run the games, Nintendo Life reports. Modded consoles use custom firmware to allow the system to run pirated games.

“Ha, looks like people running into crashing issues when quitting Mario 64 or weird skips and hitches in Sunshine are simply playing on custom firmware,” another user, writer John Linneman, tweeted. “I saw some folks talking about this but couldn't reproduce it - now I know why.”

As tends to be the case with modding issues like this, the issue is likely to be fixed for most players in the near future. Some have already posted a fix for the firmware hiccup.

The fact that “3D All-Stars” uses emulation, as opposed to properly porting the games to Switch, has garnered controversy from many players. The use of emulation has also exacerbated issues many have had with the game’s $60 price tag and limited run availability.
