it's the DS profile exploit installer if you have 4.x mset in sysnand. GW menu (launcher.dat) also has this.

 

if you sysnand is 4.x, then you have 4.x mset i.e. system settings.

 

I have a circa 2014 Gateway 3DS, games worked fine until my young nephew this week decided to format the system menu and input his username/birthdate etc....don't ask why, my own fault letting a young kid play on my system unsupervised , the system is still on firmware 4.4.10 but when selecting the DS Profile Exploit it loads his profile, I have back up of my systems SD card but I assume the GW exploit has been deleted.

As I can't find my Gateway 3DS blue card I thought maybe I could use a old Acekard DSi card but trying to run the fake DS game installer I get black screen error that the 3DS needs to shutdown, does firmware 4.4.10 block the Acekard DSi card?, any other method to get the GW exploit installed?

any advice appreciated
