Sorry for the noob question, I've gone through dozens of threads but it's still confusing to me: I have a N3DS US version, 9.0, Gateway 3.2 with the 4.5 System Settings fix. I want to be able to run DS games, either old cartridges I have or a DS flash cart. My understanding is that if I run a DS cart, I will lose the exploit and have to re-do that each and every time I want to get the Gateway exploit back. Honestly, I found it a pain the first time and prefer not to do it each time. I've read about using a ROP installer, a few have said that running it twice and changing the profile name will get the exploit to "stick", but I wasn't sure if that applies to the Gateway exploit. I also believe I read I can use flashcardtimewarp.cia to get my Blue card to function as a DS card with my 9.0 system. Could anyone kindly advise what's the easiest way to run DS games with my current setup? I don't mind running a simple installer to regain the exploit each time, but if there's a way around this, it would be awesome. Thanks for any help.
