Launchbox has nothing to do with game saves, thats a emulator job.

then is there any way i can load a sav file for the game on desmume through retroarch? ive tried tricking it into believing the .sav file included in this file - https://archive.org/details/mcdonalds-japan-ecdp-rom-training-nintendo-ds-cartridge-dump - is a .dsv file and putting it into the retroarch saves for the game, but nothing works.
