A DMP file may also be a crash dump created by Luma3DS, a custom firmware for the Nintendo 3DS. It contains a record of what processes were running when Luma3DS crashed, so a player can determine why the crash occurred. Luma3DS saves DMP files in your 3DS SD card's Luma/Dumps folder.
More Information
When a Nintendo 3DS running Luma3DS crashes, players have the option of pressing A to save a crash dump. This crash dump is saved to the player's SD card as a DMP file. Crash dumps are saved using the filename crash_dump_#.dmp , where # can be any number between 0 and 999,999,999, depending on how many crashes have occurred on your system.
How to open a DMP file
You can use Luma3DS's exception dump parser to examine the data a Luma3DS DMP file contains. The exception parser is a Python program that is available within Luma3DS's exceptions/parser directory.
After installing the exception parser, you can run the parser on your DMP file by:
