Noob question but after downgrading to 9.2, what am I able to get now? I heard of rxtools and emunand but really don't know what they do. I also heard that I can use CFW to get free games instead of using gateways but how do I get it?
I asked a similar question, but found that it was better to do digging before asking here

That should explain to you everything about CFW and the different types of CFW there is out there, explaining all of your question except for the games and emunand.
Setting up the CFW, you have to find the tutorial for that respective CFW for your O3DS or N3DS.
It not really free games, but piracy as it is stealing in a way. To get those game on to your 3DS, first set up CFW, then get the .cia files of the game. with the CFW, you then use a program like FBI to install those .cia files.
Regarding EmuNAND:
Let compare the 3DS to a smart phone.
Let say an phone has 32 gb sd card, and 16 gb internal memory (Which is where the data of the OS is stored).
Vs the 3DS, the SD card is like SD card of the phone, the NAND part of the 3DS is the internal memory part, as it store all the core info of the 3ds.
When people downgrade to 9.0-9.2, people copy and split the NAND into 2, called emuNAND and sysNAND. This proccess is similar to a computer having both Windows and Linux.
The 3DS run on the sysNAND first, then you choose to keep using sysNAND or go to EmuNAND. As such, as long as you keep sysNAND at 9.0, you can do what ever you want to emuNAND and be safe.
