Drastic to MelonDS

This script will convert the dsv save from drastic emulator to a melonDS save file

How to use

You need python 3 installed.
Specify the input save file

./dr2mds.py "Pokemon Black.dsv"

This will make a "Pokemon Black.sav" file as output You can also specify the output like

./dr2mds.py "Pokemon Black.dsv" -o "PKMN.sav"

How this works ?

MelonDS determines the type of save using exact byte count in the save file

Which needs to be a power of 2 as mentioned here.
In Importing a savefile from another emulator part under How to section

This script calculates the closest power of 2 to the save file and removes the padding.

Other ways of doing this

This can be done manually by removing the padding using a hex editor. Or using dd like this (on linux/macos)

dd if=Pokemon.dsv of=Pokemon.sav bs=1 count=524288

This will make a 4KiB EEPROM save from drastic to melonDS save.
