Nintendo has issued a 3DS firmware update which fixes a web browser exploit that was being used to run pirated Game Boy Color ROMs since January as well as inject code within downloadable games.
Another piece of code, per Eurogamer, changed the setting on the handheld to make it region-free.
The exploit was only available on older 3DS models and 2DS, not New 3DS or New 3DS XL.
Today’s update 9.5.0-23 closes the exploit by updating the web browser.
