thx! should i worry about godmode then? i honestly dont even have it on my 3ds so im not familiarized with it
also what if maybe the parental control message is to warn about its usage or smth like that? my friend has pretty much used fbi before...
So a friend of mine gave me his 3ds xl which he didnt use for a long time for diagnosing what was wrong with it (im not knowledgeable in the scene but because i still use a hacked 3ds he thinks i can do something) , he said it had been hacked...
I may try the new ram site, and download more RAM to my Switch. Not sure if ddr3 is the right ram
for it tho. Edit- no it uses floppy Ram, just like @AncientBoi
