3DS:Alternate Exploits/3dsropxploitinjector (basehaxx)

Required Reading

Basehaxx, discovered and released by MrNbaYoh uses a flaw in the games Pokémon Omega Ruby or Alpha Sapphire, achieved by editing the save file for the game, to launch the Homebrew Launcher.

This method requires custom firmware on one console. You can then use the cartridge in another console to launch the exploit.

This method will modify parts of your save file. If you care about it, create a backup in Checkpoint first.

What you Need

• A second 3DS with custom firmware (the source 3DS)
• The game Pokémon Omega Ruby or Pokémon Alpha Sapphire as a cartridge
• The latest release of basehaxx
• The latest release of Luma3DS
• The otherapp payload (for the region, device, and version of the target 3DS, pick 11.9.0-42 if your console is JPN or USA and has a version >=11.9.0-42, EUR consoles above 11.9.0-42 have to pick this if old model, or this if new model)
