Ok, firstly, I'm on a New 3ds ver. 11.0.0-33U, and i'm attempting to use FBI to install a GBA ROM (namely, Metroid: Zero Mission). I'm 99% certain that the ROM is legit. However, whenever i attempt to install the .cia file, i get the following message: Install failed! Metroid Zero Mission.cia Source: SOURCE_AM_START_CIA_INSTALL (0x13) Module: MODULE_NN_OS (0x6) Level: LEVEL_PERMANENT (0x1b) Summary: SUMMARY_WRONG_ARGUMENT (0x8) Description: DESCRIPTION_INVALID_COMMAND (0x2f) As far as extra details are concerned, my method for accessing the Homebrew Launcher is via entering the following URL on my 3ds's Internet Browser: https://yls8.mtheall.com/3dsbrowserhax.php and clicking on skater31hax The version of FBI is use is FBI 123.123 If anyone can assist me, it would be much appreciated. Also, I should mention that more or less the same error appears if i try to install anything else, too.
