I am not sure this kinda topic is allowed here or not.
But anyway
First: Currently it doesnt support new 3DS/new 3DS XL and only works for 4.0 -- 9.4 system fireware
Second: Download this Launcher.dat file #mce_temp_url# and put it in the root directory of your SD card
Third: Insert your other region game into 3DS game slot
Forth: Run the app Download play and send it to background
Fifth: Open your browser, clear browser cache and history(everytime), type go.gateway-3ds.com
Sixth: After 5 seconds black screen, you will be able to see your other region game running
ps: the fifth step may encounter errors, just try several time.
