GodMode9 VS cartreader

GodMode9 is basically a Swiss army knife file browser for the 3DS. In fact, there's also a version for NDS consoles as well. After going through the guide, systems normally continue to boot using the boot.firm Luma3DS file on the SD card root -- there's no reason to remove it. If people followed the big guide, they should not run into a situation where they cannot boot without an SD card inserted. 🤷‍♂️ GodMode9 can dump 3DS and NDS cartridge data, install .cia files, among many other things. It's an extremely important tool to have!

Was it the newest version of god mode 9 you used? Maybe try replacing the payload files with one of the older versions here?

That is GodMode9, a powerful full-access file browser for the Nintendo 3DS. Did your console boot to that when you turned it on? What happens when you press START?

I found a {thread from a year ago with about the same issue](https://github.com/d0k3/GodMode9/issues/694). They found that the issue was the system was brand new. I've been using this same 3ds since 2015. I doubt that's it. I did just buy a new SD card, but I copied everything over to my new one.

Here for GodMode9

This particular copy—which was $38 shipped; I probably could've done better, but it was convenient!—appears to have been owned by a Shin Sakuma (佐久間伸 Sakuma, Shin) who put more than a few hours into it judging from the saves. (Which I backed up using my Open Source Cartridge Reader, in the interest of preservation. 😌)

I use my Open Source Cartridge Reader to read/write N64 controller paks. (And read/write save data from cartridges.)

In the long run, another solution might be to buy/build an Open Source Cartridge Reader and use it in combination with one of the more readily available modern flash cartridges.

I'm not from Germany (I'm from France) but I did modify my Nintendo 3DS with something called Gomode9 to dump my DS and 3DS games, I did bought an external Blu-Ray reader BP50NB40 which can be used to dump PS3 games with a tool called ps3-disc-dumper and I built a Sanni Cart Reader (https://github.com/sanni/cartreader) to dump other kind of cartridge for older consoles.

if your into soldering and have other retro games you want to look into the sanni cart reader https://github.com/sanni/cartreader

If you can solder, sanni cartreader is probably the best way to go. Otherwise, you can pay to have one built.
