I've been playing Pokemon hg on the Drastic emulator for quite a while now and was wondering if I could migrate my save file over from the in game save state on my phone over to the melonDS in my PC. |

I mentioned "in game save states". Is there a need to modify the save file? |

You should be able to transfer regular save files in .sav format or whatever DraStic does (probably .sav, I have it, but I never checked), but not emulator save states. |

Drastic uses .DSV, so I change that to .sav? |

yeah, and you need to remove the extra crap at the end of the file with a hex editor, so that the size is exactly a power of two. ____________________ Kuribo64 |

Can you please elaborate a bit more on it?
I've transferred and altered the file (into .sav) and it's already on my computer, how do I get the my save to be on the emulator? |

Change its name to the same as the ROM, then place it next to the ROM. ____________________
How to write an emulator
1. throw code to be emulated somewhere 2. make memory system that allows accessing that code 3. emulate CPU 4. have fun implementing all the other hardware -- Arisotura, Tuesday 5th January 2021, 22:00:17 |

I've figured it out, here's list of steps specifically for those who want to transfer saves from Drastic over to melonDS: 1. On your device with Drastic, look for Drastic's file itself (in my case it's Phone Storage > Drastic) and find the backup folder. Inside will be your in game save. It's in the .dsv format. 2. Transfer it over to your PC 3. .dsv files won't work for melonDS, so change the file into a .sav file by changing the ".dsv" into ".sav". 4. Make sure both your ROM and save file have the same name and are in the same directory. Example: game.nds game.sav 5. Still won't work just yet, use a hex editor to open up the file. 6. Now if it's your first time using a hex editor, you might get confused (I know I did). Here's where the cool part about Drastic helped me. If you scroll all the way down, there will be a decoded message besides the binaries, it's going to tell you which parts to delete in case you're using anything except a DesMuMe emulator. Delete that. 7. Save the file and open the game. |

if you use latest melonDS from git, you can just use the import save file option I added ____________________ Take me to your heart / never let me go! "clearly you need to mow more lawns and buy a better pc" - Hydr8gon |
