I saw somewhere that 3DS games don't work on an R4 cartridge in a 3DS, is this true? And if so, do ANY flash carts play 3DS games? Thanks.


That's a shame... I really don't want to install CFW on my 2DS as I prefer not touching the consoles memory as I like it original. I would refer a way where you could go through some console steps, like Memory Pit for DSi and boot into the SD card, so when I remove the SD card, the console is not changed...Like everyone said, there are a few carts but they are outdated and a few games don’t work. You are better off hacking your system and installing a CFW for 3DS games

Custom firmware is safer than you think. We're not in the Gateway-era anymore where bricks were very common to come across.That's a shame...

You're mostly going to be using CFW to install games and homebrew as long as you know what you're doing. It's either this or nothing.
I suggest you give this a read: https://3ds.hacks.guide

Yes. If you place GodMode9 as "boot.firm", then you can create a NAND backup before going ahead with the B9S hax install.It's been a while so please correct me if I'm wrong, but wouldn't it be possible to use NTRBoot to create a 'clean'/stock NAND dump?
